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 Top Rated Answer

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

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

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.

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.

    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.

    A/C and Heat Problems. Please Help

    Question From fireprowvfd on A/C and Heat Problems. Please Help

    I have a 2007 Chevrolet Silverado that has 31,000 miles on it. I am having Air conditioning/Heating problems. Occasionally, it is like there is no power whatsoever to the console (the switches for the fan, temp, and to select what vent the air blows out of) none of the lights or anything will work. At other times, the console has power, but the blower motor will not cut on. And again, at other times, everything works fine, except the ac compressor will not come on, but the motor works fine. and then sometimes, it works just like it is supposed to. I know it isnt a fuse issue since it works sometimes, any ideas please? Thank you.

    GM has had problems with their clusters... I haven't seen any yet that are this new but the problems could still exsist....

    Try gently banging on the dash when it happens. If it brings it back, you have a cluster or connection problem....

    Instructions on Replacing AC Evaporator Core on 98 Chevy Cavalier, Z24

    Question From jmwkk341 on Instructions on Replacing AC Evaporator Core on 98 Chevy Cavalier, Z24

    I'm completely over-hauling the AC system on a:

    1998
    Chevrolet Cavalier Z24
    2.4L
    Mileage: 166,000 miles.

    Background: The AC Compressor was on its way out so installed a new one and have replaced the Accumulator, Condenser, Evaporator Tube, Serpentine Belt and Belt Tenionser. I had no intention of bothering the Evaporator, but I butchered one of the aluminum evaporator line connections coming out of firewall that goes to the condenser.

    I know that replacing the Evaporator is a big job that (presumably) involves alot of work removing instrument panels, etc.

    I have not been able to find good step by step instructions on the web as to on how to replace the evaporator core, perhaps because it appears to require alot of work and effort to access the part in the first place.

    This is my 1st post, so have mercy upon me.

    Would appreciate any help!

    Thanks, Hammer Time!!!

    This undertaking looks daunting as hell.

    Taking on this job should be good therapy for my anal-retentive OCD nature.

    Not sure if I want to tackle this now or get back to rebuilding the carbs I have totally disassembled on my 1976 Yamaha XS650C.

    I'm having to fight the urge to remove that new compressor I just bolted up and slapping on a $60 Bypass Pulley and avoid the entire AC quagmire until warmer weather approaches in a few months,

    jmwkk341:

    Hammer just found the "daunting" task for you - way to go Hammer!

    Quick read - sorry, I'm way behind. Evaps in a CCOT (clutch cycling orifice tube) system like this car are not usually a problem spot alone. As said the dang alloys are like welded after even less years.

    No oil from old compressor could be normal the noise suggests it was trashed. Do your thing. Read charging procedures up top and I can or someone provide more if you are up to it like total system capacities or educated guesses for how much oil to use for what was replaced and it is guessing unless you start from completely flushed out empty. No dipstick for that and it's imperative to be close.

    Even I own one that when the time comes for a compressor hope I can catch it before a meltdown and when much newer started putting PB on those just in case so evap wouldn't be involved!

    Good luck. "Measure twice, Cut once" as they say

    Response From jmwkk341

    Thanks Tom. I appreciate the offer of help.

    Going into this, I had absolutely NO intention of replacing the evaporator core due to its location. All connections came loose rather easily, but on that last disconnect I just did not take the care necessary to avoid twisting the damn tube coming out of the firewall. I should have used some PB Blaster and put a wrench on the hex connection to immobilize it while wrenching off the black nut on the AC Evap tube.

    BTW, I did have a local shop recover the R134a in the system prior to be tearing into it. Cost me $27.00.

    I have come across a couple Youtube videos on removal of the Cavy's dash/instrument panels and so forth in order to access and replace the factory radio, so I'm hoping that footage will be of some help.

    i do have some questions - I was not able to pour any oil out of the old Accumulator either. Is that unusual?

    When I get to the point of charging the system, how (or) will the lower ambient temps (even in my garage) affect pressure readings and charging conditions as compared to performing this work in warm or hot weather?

    Response From Tom Greenleaf

    OK - A chart and they can be totally wrong for a '98 Cavalier (say all engines) 24 ounces 134a and 9 oz. PAG 150 oil but that's from totally empty and I'm surprised that much. To get oil out of an accumulator drill a hole in the bottom but some is still held up for sure. Heat it if you wish for more. My guess is that plenty of oil settles in condenser but varies by car and designs.

    General: When/if a component is replaced you add how much you could dump out plus a couple for a system with that oil capacity IMO and it is subject to opinion and what happened. A blowout from a rock thru condenser may blow a lot of oil out or any sudden loss.

    Know that normally a plain vacuum pull and that's critical should not remove significant oil. If you don't have your own pump then rent one. Don't just count on a shop down the street as YOU want to see it hold steady and if good you can add thru high side into the vacuum engine off with liquid into that vacuum till it reads positive pressure so NO air gets in. Purge lines with a spit (just a spit) of new gas before hooking them up. Air is the enemy with its moisture.

    Done (retired) from this but still check out stuff live if asked. Hasn't been that hot here in a couple years for that long and the extremes seem to bring out the weak links/leaks in system faster with the higher pressures.

    Just to refresh and remind you once you have refrigerant and a gauge set or whatever you are using is to think hard what is pressure, what is known vacuum and what/where the pure gas is. Be fast but don't choke compressor when charging when all done if forcing compressor to run. Once some cooling at vents is happening the compressor should be getting some lube - critical.

    Hang in there,

    Tom

    Response From jmwkk341

    My new vacuum pump is a U.S. General Two Stage, 3 CFM, 1/3 HP unit that I bought from Harbor Freight.



    Response From Tom Greenleaf

    Great. Anything that can just pull a full vacuum is fine. Really expensive ones are just faster and those venturi ones can't pull the full 29.92 Hg at sea level adjust 1 Hg/1,000 ft. of elevation is ok

    Response From Tom Greenleaf

    Instructions exist but I don't have specifics with step by step and at the age things may break doing the evap and it may not fit right as the original. Damage is done and too bad because depending on what was wrong with compressor you frequent aren't going to get that dang alloy stuff apart without damage to do the accumulator and yes most compressors will want a new one or give you a hard time for warranty.

    If nobody here has the specifics AllData.com will for I think $27.50 but that is unlikely to tell you or discuss a poor fit and it's hard to say depending on any complications. Not to discourage you but A/C is not very DIY friendly without some comprehensive know how or your work so far may be all in waste.

    1. What was wrong with the compressor?

    2. Did it leave debris and how did you guess at how much oil to use?

    That's just the tip of the iceberg and hope you bought a new compressor no a reman,

    T

    Response From jmwkk341

    Thanks, Tom.

    The old compressor had been making a shrill, high pitched metal on metal grinding noise when the clutch was engaged. Also, there was a fair amount of shiny metal shavings around the compressor.

    I was not able to drain ANY oil from the old compressor. Since I'm replacing all components (accumulator, condenser, evaporator and lines) with new ones, I believe the system will hold between 8-9 ounces. I put 3 ounces of PAG-150 into the compressor. I'll add the appropriate amounts of oil to the other components per the GM info that I have.

    I've never performed any AC work before, so this is definetly a crash-course that I have the luxury of taking my time with since this is not a primary or even secondary means of transportation.

    Thus far on this car, I have completely (and successfully) replaced the rear drum brakes, replaced the power steering pump & replaced the O2 sensors. Pretty routine work for most, but is work I've never done before. This is the first car I've had where totally botched self maintenance wont result in me being stranded w/o transportation.

    Yes I bought a new AC Delco Compressor.

    Thanks kindly for the reply.
