2001 Ford Focus Water Pump

Question From jtr27 on 2001 Ford Focus Water Pump

My Water pump Has Siezed up And I Have Changed Pumps in the past on Gmc Jimmy and Older Ford LTD But not on smaller tighter harder to reach motors How hard is it to get to and while im doing that is it worth changing the timing belt ? 117,000 MILES THANKS FOR ANY TIPS YOU MAY HAVE....

Response From Tom Greenleaf Top Rated Answer

I'd have to see it to know the exact approach. These things can cause you to add all kinds of tools to your collection that work in tight places. Scope out whether you get a shot at it thru the wheel well with tire off.

Definately consider the timing belt as you are about ready for the second one! If it's original you are way overdue, T

Response From Guest

thanks for the advice through the wheel well will definetly be my best approach and timing belt is way overdue let you know how it goes. jtr 27

Question From Guest on 99 GMC 2500 series

I need some advice on what I should do with my uncles truck. He was pulling a trailer when all of a sudden the water pump broke and it overheated soon after. Replaced the water pump and filled the radiator back up and come to find out the water is going directly into oil pan. I assumed there is a crack someplaace. Now this truck is in good cosmetic condition, good interior and starts right up. What are some ideas on what I should look for or to do with it??

Response From Tom Greenleaf Top Rated Answer

Oh Damn! That would suggest head gasket or intake manifold problems or cracks in either. Sorry but NOT a good sign. Lower end of Chev V8s are tough but the top isn't like the real old ones. Hope it's not as bad as I think it might be, - T

Question From Guest on 90 GMC Silverado 1500Antifreez Leak

Hey guys, hoping somebody can give me some advice on what the problem could be . I have noticed coolant leak over the last two weeks. looks like it is coming from the bottom of the engine.. What could it be causing this .. my mechanic seems to think water pump. What do you all think? Thanks for your time

Response From steve01832 Top Rated Answer

Crawl underneath the vehicle with the engine off with a flashlight and look up at the water pump. On the bottom side of the pump you will see a small hole just behind the fan. On GM vehicles, this is the most common place for them to leak. If there is coolant around it or if you see a stain going down the pump from the hole then the pump is leaking. Don't let this go too long because when the pump seal finally fails, coolant pours out of there.

83 gmc truck no heat

Question From jkkennedy on 83 gmc truck no heat

Hello I have I 1983 gmc c1500 truck 5.0 engine I have all of the hose hook up and took of the the heatercore to see if maybe plug blow on one end of hose water came out easy you turn on the heat and the thing blow warm for just a min and then cold air comeing out of it let truck run for 30 min felt the water in the rader it was just warm not hot.

Response From Tom Greenleaf

Coolant must be full at radiator and can take a cycle or two to burp out air after being open. Is heater truly cold or just lukewarm? From cold, upper radiator hose should stay cold to the touch till engine approaches the thermostat's rating, typically about 195F for this engine.

If the hose warms up early then the thermostat is letting coolant pass too early to be cooled when already not warm enough,

T

Response From jkkennedy

The radiator is full and the heater is truly cold just put a new thermostat that is a one 195f thinking maybe this is what it was but no still cold air no heat at all check the bypass door it is hook and working so that not it so what to do next

Response From Tom Greenleaf Top Rated Answer

Does your temp gauge stay steady? Are heater hoses at least warm. Should be about too hot to touch - careful. I think temp blending (for heater) is mechanical (cable) but can't be sure on this one. Rare but there are water pumps that will be directional and wrong or impellers not up to snuff,

2002 Envoy runs hot

Question From Rickster66 on 2002 Envoy runs hot

2002 GMC envoy 4.0 straight six runs at 210 degrees or a little over that. 115K miles. I was wondering if this model had issues with the water impeller was subject to deteriorating?

Response From Tom Greenleaf

That's what your dash gauge says? Does it stay steady there once warmed up or bounce higher and lower? That's about where many would run so is this a new spot on the gauge to you or just questioning it now?


Impeller issues are near always from lack of using coolant with additives and changing it on a schedule. That would probably produce odd fluctuations of temps and difficult for heater to blow hot very well.


Not likely unless long term coolant neglect for that.


You may be just normal for this vehicle. Dash gauges are not meant to pinpoint exact temps so well and if worried check the temp at the thermostat's housing should stay about the thermostat's rating on this layout and definitely while driving along short of super extreme ambient temperatures,


T

Response From Rickster66

Mostly stays at 210 unless I'm stopped in traffic then it will creep up to maybe 220 or so.

Response From Tom Greenleaf

OK - Still could be normal. I'm impressed you are paying attention at all. HT = Hammer Time above mentioned this should know to increase fan speed at some point so there would be some variation of your gauge reading which isn't very exact IMO vs what the vehicle's computer controls are seeing.


Worth knowing or I would make sure higher fan speed does in fact work.
Some trivia on these temps as normal: We know water boils at 212F WITHOUT PRESSURE. Coolant mix really only raises that to about 215F or a tad more WITHOUT PRESSURE. This would be a problem temp if you gauge was accurate WITHOUT pressure but you do or should have about a 15lb pressure cap on the cooling system which raises the boiling point keeping coolant a liquid 3F degrees per pound of pressure. That puts the breaking point at 257F and you don't want to get near that much.
For any reason loss of pressure this would be boiling now and that would be a real problem. Vapor doesn't help much (where boiling) in system then problem would result.


The higher temps of normal really want to operate at the higher temps to get the most out of fast and clean fuel use giving you the most performance designed into it.


The key here is knowing it's normal and you asked and should if not at a site in person with a tech at a check up bring it up for checks of anything you question.


It's hot in lots of place right now. Never mind air temps and forecast temps right over the road with a hot vehicle in front of you at a light or in stop and go traffic you system is really working hard and YOU are no doubt asking for A/C so working harder yet!


It's important to now your vehicle what is normal or an early warning before it's trouble.


Even this old there should be tons of info in a really boring read in owner's manuals. Only real fault is most will suggest anything you go to a dealer that sells them and use only their products - that's expected. The info otherwise is nice to know. Bet not one in 10 people ever touched an owner's manual to their own car.
Yes - you can find most on line so if you don't want to go get it can read it from whatever device you are using and should - anyone should,


Tom

Response From Rickster66

Thanks to all replies!

Response From Discretesignals

Just to add. If you are unsure about the state and condition of the cooling system, have your local repair shop inspect it to be sure you don't have any issues.

Response From Tom Greenleaf

Good point DS - unlocked for time being. OP - yes you should want to know cooling system is good as a preventative check at this age. Know it's good ahead not on the side of a road.


When many now keep vehicles much long as daily drivers a periodic check list of all systems is a good idea much like you would buying a used car even if it's been YOURS for years.


I find this stuff way too common with the rage and popularity of the ever present 10 minute oil change places are not doing folks a great service in 10 minutes. Nice that places fill up low fluids but don't know when one is low it means trouble lurks and they are NOT mechanics - know that!


T

Response From Tom Greenleaf

OK - I'll close as question solved - this time things are normal for just what was discussed. OP may ask any moderator to reopen the thread if wanted,


T

Response From Hammer Time

First, you don't have a 4.0, you have a 4.2.

Your cooling fan is computer controlled through Pulse Width Modulation so the 210 degrees is both intentional and normal. The computer has the ability to speed up the fan at any time it deems necessary.

Response From Discretesignals Top Rated Answer

The impellers are metal. Haven't seen one that had deteriorated the impeller to the point of overheating. What is the condition of the coolant. Seen many water pumps with bad bearings on the trailblazers. Around 210 is normal operating temperature.
