2005 impala overheating problem

Showing 4 out of 4 Posts
Question From jwd2256 on 2005 impala overheating problem

Car info:
2005 Chevrolet Impala, 3.8 Series II, 90,000 miles.

I'm having a problem with my 2005 Impala LS overheating. I took it to a Firestone Auto Care shop and they did a diagnostic test on it. What they told me was that i need to repair or replace my radiator, change thermostat, replace radiator cap, and they recommended that i changed the radiator hoses in a few months. I took my radiator to a radiator repair shop where they checked for leaks and cleaned the radiator out, then i put the radiator back in and replaced the thermostat and radiator cap. It still overheats though. The temperature gauge fluctuates a little while i'm driving and if i go up a parking garage the temperature gauge need goes almost up to the red zone. I would really appreciate any help

Response From Discretesignals

If you have the ac turned off and it is running hot, are the cooling fans running on high speed? Do they ever cycle off?

Did you remove the radiator cap and make sure there is enough coolant in the tank after the engine has cooled down overnight? Did you pressure test the system after the radiator repair to make sure you don't have any other leaks?

Response From jwd2256

Yes, if i have the AC turned off it still runs hot and the fans switch on when its hot and then turn off after. I did check the coolant level again and it was full still. I didn't pressure test the system because it costs $90 each time where i live. Firestone never said they found any leaks so i dont know.

If you have the ac turned off and it is running hot, are the cooling fans running on high speed? Do they ever cycle off?

Response From Discretesignals Top Rated Answer

Yes, if i have the AC turned off it still runs hot and the fans switch on when its hot and then turn off after.

These fans are designed to run at two speeds. High and low.

If the fans come on and then go off while the engine is idling with the ac off, your not overheating. If the fans are running full blast and never shut off and your gauge is getting into the red, your overheating.

There could be a problem with the gauge. If you had a scan tool, you could monitor the engine coolant temperature. Fans on those will kick on low speed around 217 degrees F. If the engine temperature gets up to 230 degrees F, the PCM will turn the fans on high.

You can also use a laser thermometer aimed at the base of the coolant sensor to see if the temps jive with your gauge.

overheating with heater on

Question From magicman201080 on overheating with heater on

I have a 2002 Chevrolet cavalier that all of a sudden started over heating with the heater going. heated up to over 200+ degrees last line before fed. shut heater off and temp went down. engine is a 2.2 has 155k miles please help. have had evap problem for some time and replaced all evap parts. now the heating problem starts

Response From Discretesignals

Doesn't really make sense for the vehicle to overheat when you turn the heater on and then cool off when the heater is switched off. Was the ac compressor running when it decided to start running hot? AC compressor will run on some models when you have the mode selected for defrost Does this overheat while your idling or cruising when you turn the heater on? How is the coolant condition and level. Might need to get hold of a scan tool, that you can watch the ECT value on, and see if it jives with the gauge.

Response From magicman201080

no sir the ac compressor wasn't running and the car heated up then shut heater off temp went back to normal range. was told could be heater core plugged. but I don't know fluid levels are at correct level and doesn't seem to change when checked heats up both idle and moving

Response From Tom Greenleaf

? This all began with replacing an A/C evaporator? Almost all are quite involved and most or many vehicles need or allow flow thru heater core and adjust or block temp with diverter/blend doors. Are or did you get heat when asked for or nothing?


The common denominator is the evaporator job then this so somehow something probably went wrong with that job. Both heather hoses should feel warm/hot in hand with any credible engine temp and if one is stone cold something is wrong. Yes a plugged core that is used (if so) as a bypass flow of coolant for engine will matter but all the time not making sense with just request for heat and showing hot.
OK - My question is do you get heat when asking for heat only on floor vent outlets? If not ever we check on why not,


T

Response From magicman201080

car was warm and melted ice on windshield the evap was the canister and surge soloed not the ac. car was running fine now today it overheated and when I shut off heater the temp went right back down to the normal temp around 195

Response From Tom Greenleaf

Let the confusion rule. When you mention an engine heating issue and recent "evap" I think normally techs would take that as A/C not evaporative emissions parts!


So let's start over: Still you say this began exactly when those parts were replaced? I'd just look and see if anything is obviously out of place, check coolant level now and you need to know that it's full in the radiator and engine air free despite this "evap" work shouldn't really have involved draining engine coolant but a wild maybe some wire got involved?


As DS said right away it's not consistent with use of heater and overheating, in fact if you were running too warm even on a hot day requesting heat should HELP cool engine not the other way - that leaves coolant level, plugged core if used as a by-pass for cooling system. I'd have to plain look.


Still - asked you if heater worked on floor vents not if it melted ice on windshield suggests you were using defroster/defog/or a section for both heat and mix with floor vents which does engage compressor if it is even close to warm enough under the hood it will engage compressor.


We need that OUT of the problem if there's a problem at all. Many of these cars do not hold a steady #/spot on the dash gauge and perhaps you are just now noticing?


Various ways when compressor is in a request mode fans come on in many needed or not for A/C and some know it's cold and don't and I'll never know which ones do what all off the top of my head.


Back to topic: If I had to guess you are low on coolant in radiator/engine which will cause bizarre behavior. If it wasn't touched then you need to know why if found low at all,


T

Response From magicman201080

had a service person look at the antifreeze and the level said both level and condition was fine. am going to try driving home later with out the heater on in any mode and see what happens will also stop and have a repairman look at it and see if they say what it is. have little to no money on fixed income and cant really afford this but ...........

Response From Tom Greenleaf Top Rated Answer

I asked for level in the radiator not easy to know if this doesn't have a radiator cap so that info is useless.


When it shows warm to near hot does fan for radiator come on under hood? That you can check. If cool weather some may not need to come on much or at all even sitting still,


T

Response From magicman201080

yes as it heats up the cooling fan kicks on and runs for awhile and then shuts off. was told that is normal operating for that. has no cap just plastic container on passenger side of engine compartment

Response From Tom Greenleaf

OK - That type the tank you see thru is also where the pressure cap is where you would ad BUT if there's a problem or system was drained for any reason you can't just fill the system from that!


Vacuum filled if it was drained or other tricks.


OK - You see if even the hose from that tank to the radiator had a leak it might not draw coolant back from tank to radiator and engine as it normally does when cooling down so air would be drawn back but the tank looks like it's fine - lousy way for car makers to do it that way.


Doubt you have any fancy tools so try this. Cold start, feel upper radiator hose for NO pressure by squeezing it. It may even make a sound of sloshing and air? Now as engine warms up that hose shouldn't have much pressure very quickly but see if it does for another possible problem. Let it warm up enough so hose now has some heat (careful) in it and by then some pressure. If none of that there's a problem to fix first before finding out what else might be wrong if anything.


System idea on this: Coolant expands when warmed up and sends the extra to that tank which is also going to allow pressure by the cap's design. As it approaches the pounds of the rating of that cap it lets coolant in and you see the marks for full cold and hot on those tanks.


Now when it cools the cap again when coolant is shrinking is only going to let back liquid coolant not air so system if perfect and designed perfectly would self purge out air and draw back just coolant/liquid but either anything wrong or not purged of air when working on it, it may never get all or enough air out and there's your reason for erratic temp gauge and heater use.


It stinks but you really may not know if system is full or if touched when the "evap" stuff was worked on and it does take time and some effort for anyone to fill the cooling system up properly - some may get close and think it will self purge out what's left and it never does.


Need to know if you have to take it somewhere and just have it vacuum filled. If so and problem is all gone that was it. Air/vapor will mess up sensors accuracy, real hot spots and perhaps sudden cold readings and so on. Gotta know it's full...........

Response From Hammer Time

Why are we messing around with anything? If the fan is cycling, the temperate is under control. You're just trying to fix something that isn't broken.

Response From magicman201080

hammertime you haveno idea how to fix anything and you are rude and think you know it all you don't need to respond to me anymore ill deal with the professionals that are on here

Response From Hammer Time


magicman201080 You keep running your mouth and you will be looking for another forum.

Maybe you think this is my first rodeo and I have no idea what I'm talking about. You would be very wrong about that. YHour car is operating exactly as it was designed to.

Response From Hammer Time

Maybe you need proof.


Cooling System Description and Operation

Cooling Fan Control

The engine cooling fan system consists of one cooling fan and one relay. The relay is powered by the battery positive voltage circuit and controlled by a switched ground from the powertrain control module (PCM).

During operation, the PCM supplies the ground path for the cooling fan relay through the cooling fan relay control circuit. This energizes the cooling fan relay coil, closes the relay contacts, and supplies battery positive voltage from the cooling fan fuse through the cooling fan motor supply voltage circuit to the cooling fan. The cooling fan motor is grounded through its own ground circuit.

The PCM commands the fan on under the following conditions:

  • Engine coolant temperature exceeds approximately 106°C (223°F).
  • A/C refrigerant pressure exceeds 1310 kPa (190 psi).
  • A/C is requested and vehicle speed is below 100 km/h (62 mph) with A/C pressure above 1413 kPa (205 psi).
  • Vehicle speed is less than 8 km/h (5 mph) for more than 750 seconds. The fan will turn off when vehicle speed is greater than 8 km/h (5 mph) for more than 20 seconds.

  • Response From magicman201080

    was told by a repairman that it is the water pump and that it is not pumping water. the bottom hose is cold and the top hose is hot with no water circulating thank you to the professionals on this site you were very helpful as for others well.............................. enough said about them

    Response From Hammer Time

    If I were you I'd be looking for a different repairman because he is wrong but you'll never come back here and admit he was wrong and you wasted your money.

    Response From Discretesignals

    I agree with HT. Something doesn't add up. If the water pump was bad, the engine would overheat fairly quickly. Also as HT stated the cooling fan would be running high speed and would never shut down. A pump that isn't pumping that great may also cause you to have poor heater performance.

    Which engine is this? The ECOtech or OHV LN4? Take a pic of the faulty pump when your mechanic gets it out. Post it up in here. Curious to see what it looks like.

    Response From Hammer Time

    I don't even get what he is chasing here. It appears to be just the fact that the temp gauge goes over 200. That isn't going to change no matter how many pumps he changes.

    I bet I don't get an apology when he finally realizes I'm right either.

    Response From nickwarner

    As an ASE certified master tech, HT actually does know how to fix something. You have already stated you do not.

    He has tried to explain to you that you do not have anything physically broken on your car that will damage your engine and cause you to need to spend the money you have stated you do not have to spend.

    Your cooling fan is set to come on at a certain temp to draw the engine temp down, and once it has done that to cycle back off to prevent the engine from running cold. There is a sweet spot it needs to run at tempwise. If your car was overheating, the fan would be staying on as the ECM would realize it had not yet succeeded in dropping your engine temp enough. The fan coming off proves it has done this.

    Your heater core isn't plugged if you are feeling good heat coming out of your vents. A plugged core gives off little to no heat. It also cannot make your engine overheat. It is essentially a mini radiator placed there for your comfort, not for engine cooling.

    Your gauge and your computer use two different sensors to read coolant temp. It is possible you have a bad one for the gauge or some other issue giving you these readings, and remember as HT pointed out this car was designed to run 225 degrees at idle.

    But I really think getting lippy with a moderator is a bad idea whatever forum you use, especially if you had actually taken the time to read the posts and realize that all of this has already been explained to you and you seem to either just not understand it or just seem to want to believe no matter what that something is wrong with your car.

    Response From Hammer Time

    Shutting off the heater has nothing to do with your overheating. I'm suspecting you still have air pockets in the system that need to be burped out.

    Don't forget, this engine is designed to run at over 225 at idle so that shouldn't be an issue.

    Response From magicman201080

    how would I have gotten air into the system? nothing had been repaired that had to do with the cooling system

    Response From Hammer Time

    If the fan is coming on and then shutting off, the car IS NOT overheating.

    Response From magicman201080

    was just told that it sounds like a water pump gone bad. don't see any leaks coming from it and antifreeze levels are fine

    Response From magicman201080

    im sorry I sound stupid but when it comes to cars I am. im not a mechanic and have to ask the professionals for help. I try everything I am told to try and still have no clue. if I am looked at as a problem please let me know I will try another site. thanks for all the help. I really do appreciate it.

    Question From fhart123 on dual climate control

    on a 2004 chevrolet suburban dual climate control when in heat mode the driver side will blow cold air and the passenger side blows hot air as it should. Can someone please tell me what could cause this problem ? It has the 5.3L engine arnd 85k miles

    Response From Hammer Time

    Judging by the symptoms, you have a bad blend door actuator on the driver's side.

    Response From Discretesignals Top Rated Answer

    First off, take the radiator cap off when the engine is cold and check to be sure the radiator is topped off.

    If the coolant level is good in the radiator, your going to have to take it to a shop that has an enhanced scan tool that can retrieve trouble codes stored in the HVAC control module and be able to view temperature door counts to see if the actual door position and requested door position jive or not. If they don't jive, it's possible that you could have a faulty air door actuator.

    Question From bambino12 on 2000/Chevrolet/Cavalier/Cooling Leakage

    Hello All!

    I own a Chevrolet Cavalier year 2000, 2.2L engine. It is about 70 000 miles

    There is a leakage in my cooling system.

    Drops do not come either from radiation nor from coolant deposit, nor from the water pump.

    I can see drops coming from a strange pipe.

    Im bad to explain things, I attach a picture

    There you can see the plastic pipe Im talking about. Also, you can see the coolant pond on the floor.

    About a month ago I took my car to service (tunning, refill all levels, oil change, engine wash and so on). I wonder if the guys at the service center forgot to connect something.

    Also, I don't use this car too much, I only use it on weekends. Last weekend I just noticed a bad smell (like something burning) and that´s the way I noticed there was a leakage, it was the smell of hot coolant fluid. I also replaced the deposit's cap, since the previous one just broke, I guess because of the heat.

    I noticed then the "low coolant level" warning light in my dahsboard.

    Thanks all!!!!

    Response From Tom Greenleaf Top Rated Answer

    That little rubber elbow is to let water (condensate) from the air conditioner out in season when they make water in humid weather. The same case (inside car) hold the heater core which is a miniature radiator for heat. If that leaks it could leak engine coolant out that hose but usually there is a sign on the right interior floor or if you look up under there it might show some coolant - is slippery in fingers compared to plain water - wash hands please if you get it on them.

    That's what the thing looks like to me. I could be wrong and a heater core replacement should be verified by someone checking that out in person. Sometimes a hose can leak or have a pin hole that squirts like fishing line and make some place show coolant and the leak isn't there at all!

    I'd have the system pressure tested and point out where you have seen coolant but don't make the diagnosis for them or you just may get a heater core and not need it! Fill cooling system now with proper mix of anti-freeze and water - usually 50/50 - filled at radiator first and then the tank (recovery) that you can see the level in. If this doesn't have a radiator cap it will have to be filled by taking a hose up high off as it may not draw in coolant from just the recovery tank when low enough to make the light come on or if the leak won't allow the vacuum action to draw it back in,

    T

    Good luck,

    T

    Response From bambino12

    Hello Tom!!

    I think you are rightm although my car lacks Air Conditioner system. In any casse I think you and Jim are right.

    Will check the interior floor.

    By the way, this morning I filled the deposit(recovery tank). Im not sure if radiator has any cap.

    Well, I just filled deposit/recovery tank to the indicated level when cold.

    Then I turned on the engine for about 5 minutes.

    I looked at the floor, I noticed drops, continuos, not a line of fluid, just drops but very continuos, I would say about two drops per second.

    It took me some time to identifie such elbow pipe that seems to go nowhere (as Jim said)

    Will check the floor.

    Many thanks!!

    Response From Tom Greenleaf

    That elbow pipe is just a drain for moisture if what I'm thinking and shouldn't have coolant either way as said. If all you have is a pressure radiator (even if not on the radiator itself) cap on the tank you added to then that cap is the pressure cap - if you have to unscrew it, it is the pressure cap and you could leave it loose to stop the dripping or slow it down. That tank is not capable of filling the whole cooling system once the level you can't see is down and you said a light was on which is probably sensing liquid in an end tank of the radiator itself which should always be full even though you can't see it.

    This needs to be looked at and almost certainly is needing a new heater core. They almost always drip into the car when they are the leak as you have noticed.

    If you leave the pressure cap loose that's just a temporary way to slow down the loss of coolant - not a fix. Don't lose the cap either.

    You would get some coolant into the radiator and hence engine by just filling that reservior and start engine for a while - like just enough to show the temp needle coming up and shut it off - just wait till it's cool and it probably has taken back some coolant from that tank. If so - do that a few times till "low coolant" light is out and your next trip should be short and to get this taken care of. Now is a good time to be thankful for not having A/C as that would make the job much more complicated and expensive.

    Hey - if you are going to drive this at all like this pay sharp attention to the gauges. Run heater on full heat request and low fan and if that goes cool on you the coolant is low or boiling - odd but an overheating car doesn't heat the interior thru the heater! This is probably just in need of the heater core right now and if you pay strict attention and do not overheat the car it would really help limit any further problems from overheating.

    Good luck with it,

    T

    Response From Lando10101

    Regardless of anything the system will have to be opened find a good mechanic some of them heater cores require major teardown . Good Luck

    Response From bambino12

    Tom and Lando,

    Thanks again for all of your valuable help.

    I keep note of your advice and it is amazing how much one can learn from this forum.

    Tomorrow I will take it to my mechanic that is less than a mile away from home.

    I pray this would not be an expensive repairment.

    I will report any progress.

    Thanks again!

    Response From Tom Greenleaf

    Thanks for letting us know. This car with no air conditioning should be MUCH easier to do what is usually a difficult job. I doubt it would be cheap but having to deal with A/C components can be more than half the work of replacing a heater core. Either way it's not really a good do it youself job unless you have some strong know how with these sorts of things - it's involved with assorted dash parts to get the case apart and or out to replace it,

    T

    Response From bambino12

    Hello Tom, Jim, etc..

    This morning I just took the car to my usual mechanic.

    He did exactly the same diagnostic as you. It is the heat core. He explained me that this much like a small radiator that works to heat the air for defroster.

    He gave me the option of totally disconnect such damaged radiator, and do some sort of bypass to avoid it and have the cooling system working just fine, at the price of lacking defroster.

    I decided to go the expensive way. He is charging me about $300 bucks for all the job, including a new heat core.

    I sometimes doubt wether mechanics really install original brand new parts. I decided to trust him as he is giving me warranty.

    Do you think I got a good deal? Was I fooled?

    many thanks!!

    Response From Tom Greenleaf

    That sounds great! You can bypass the heater in some circumstances as a temporary measure. It couldn't be something you could live without with any ice or defrosting need though - at least around here.

    That's a nice price. Keep in mind that many cars that have A/C that must be emptied and refilled to do this job and that part alone would cost what your whole job is quoted for. Some of the cores can be fixed but most people today would replace them.

    Good luck. All seems fair to me,

    Response From Double J

    Is that just a small elbow type hose,that comes out the firewall and goes nowhere..
    If so..thats the evaporator case drain...
    The heater core is probably leaking.
    Do you notice any coolant inside on the passenger floorboard under the carpet?
    Any unusual steam coming up thru the defrost duct..film on the windshield?
    Thats what the pic's look like....

    Response From bambino12

    Hello Jim!

    Yeah!!

    I think you are right.

    My car doesn't have Air Conditioner, but it certainly has defrost/ventilation fan.

    And the smell certainly comes from the defrost/ventilation ducts.

    I will check about coolant inside the passenger floorboard.

    Also, will turn on the defrost to see if some steam is forming on the windshield.

    As I use my car little (only on weekends and for very short trips) I have not had time to look at details, but will do some testing.

    So.... is the heater core some kind of device that heats the air for defrost purposes?

    Do you think it would imply an expensive repair? Just don't want me to be fooled by my mechanic.

    Many thanks!!!!!!!

    I will report my findings! This forum is great!

    Response From Tom Greenleaf

    Same heater core for heat or defrost. Not sure if the drain hose is still used for car without A/C or not but it shouldn't be leaking coolant there either way,

    1989 Chevrolet 1500 5.7 Running Rough, dies

    Question From JesterzLaf on 1989 Chevrolet 1500 5.7 Running Rough, dies

    1989 Chevrolet 1500 Silverado
    Engine: 5.7
    Mileage: 148k miles showing

    Where do I start on fixing this. I haven't replaced anything yet, figured I'd get advice first rather than simply throwing possible parts at it to fix it.

    Truck runs great driving normally. When I start it, sometimes it dies, and I have to give the gas pedal a pump to keep it running and it smokes alot at startup (seen smoke when pulling away from a light too). Then when I put it in gear, I have to give it gas to keep it running. At idle or at a light/stop sign, I can feel it running a little rough. I looked under the hood, and the EGR was bypassed, the firewall plugs for the heater hoses were bypassed, the a/c unit was removed (just bought truck yesterday). I didnt hear any obvious air leaking from vaccuum lines. It does have a small chrome breather I know I need to replace. I had parked it today at the revenue office and was in there about 30 minutes. I came outside and popped the hood when it wouldn't start, under the hood seems to be very hot (more than normal) but my temp gauge says I run between 160-210. 210 being the max it got to but dropped quickly and stayed down since. I covered the radiator with a rag and opened it, water wanted to spew out. Once I had it open, I dunno if it was because I slowly opened or if was really something else, but there were bubbles in the coolant. Best way to describe them would be like suds from soap lol. I put the radiator cap back on and it started after a couple cranks. It starts when cold, but after it is warm, it has a hard time starting. Being a new vehicle to me, I'll obviously be switching out spark plugs, wires, fuel filter, breather, oil, transmission fluid, trans filter, and flushing the radiator. Dropped by a friends shop and he said it could be the fuel relay. Then he seen the smoke when I started it and he said it might be something worse. The truck wasnt driven much lately before I bought it. It does have good power and take off. Runs smooth while driving. Thanks in advance for any assistance. If I need to give more info, lemme know and I'll get it to you asap. I looked through other threads and will certainly give a response as to the problems once resolved for others future problems.

    Response From JesterzLaf Top Rated Answer

    Update: did all those I mentioned before, plugs/wires/fuel pump relay/etc and still having problems. I followed the vacuum diagram and reconnected all the vacuum lines to where they need to go. The EGR diaphram is good. One new thing I noticed, the muffler looks like the pipe was shoved in in the front. When running, smoke comes out of both the muffler front and the end of the tailpipe. Maybe the exhaust is choking it? Friend is going to work that problem at the shop. When I started it up today, the truck idled kind of like with a lope, then leveled out and idled perfect. After a few minutes, it started loping again and eventually stalled after a few minutes of it loping. There is also a vacuum tree with one inelt behind the throttle body that was blocked off at the end of the hose. I looked at another truck, and instead of having the vacuum tree, it had a plug in that place.

    Sorry, trying to be detailed as possible so I could get some help. I would just take it to a shop but I'm disabled veteran still fighting the VA for my benefits and barely staying afloat. Any help would be greatly appreciated.

    Response From Hammer Time

    First make sure you have no vacuum leaks, the EGR isn't sticking open from carbon and the EGR base plate isn't rotted out. Once all that is eliminated and you still have a problem, you may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
