1997 Pontiac Grand Prix - Running Hot

Showing 2 out of 21 Posts | Show 19 Hidden Posts
Question From upmm019 on 1997 Pontiac Grand Prix - Running Hot

I have a 1997 Pontiac Grand Prix GT - 3.8L - Non-Supercharged.

Car has about 120k on it but the motor was replaced recently.

Car is running hot and I'm not sure where to start in regards to getting it fixed.



Temp runs up to the red before the fans kick in at all. then when they do... the temp goes down to the blue. It never runs any cooler.

I just put about 2500 dollars into the car and really cannot afford to get much more into it.

I checked the coolant level and it's full.

the fans come on but not until it's super hot and when they do come on I cannot say they are super loud, etc.

What should these cars run at normally for a temp after being warmed up?

When should the Fans kick on?

any other suggestions?

The car is my sons and I've told him if it gets hot to just turn on the heat to bring it down. He has been doing that often so it's time to figure out the problem and have it repaired.

Any help would be wonderful...

Response From Hammer Time

One thing you will find with these cars is that they will run a lot hotter in slow traffic situations with the A/C off. That is normal and intentional. The fans aren't programmed to come on until approx 226 to 228 degrees if the A/C is not on. If the A/C is on, they run all the time.

Cruising on the highway, it should stay around 200 degrees..

Response From upmm019

My son drove it yesterday and we drove highway speeds in SD (65mph) and he had to turn the heat on to keep it cool.

that is not normal at least in my non-mechanical background.

The thermostat was replaced new with the new engine about a month ago along with the water pump.

I'm wondering what my next step is here.... new radiator? new temp control? new fans?

I can only tell you that last fall I took the car (before all of the engine troubles) to have the coolant flushed as it was all gummed up inside... Almost looked like cottage cheese at the top side. Not sure if the prior owner or someone mixed dexcool with regular antifreeze or what....

When I looked at the coolant the other day it was not like that but it did appear to be dirty looking but then again I don't think the garage put the true dexcool back into it... I think there is some new alternative to the dexcool and it certianly was not the green stuff.

my other car that has a v6, its not a pontiac but that vehicle never runs over 210... probably not a fair comparsion but I don't think it should get that hot but perhaps I'm totally wrong.....

Response From Hammer Time

Mixing coolants won't hurt anything at all. It just won't be a 5 year coolant any longer. As I stated before, these temps at low speeds would be completely normal but if you are seeing 220 or higher at highway speeds, then you have a problem. The sludge you spoke of concerns me. Dexcool will turn into a sludge if left in the system too long or if run with a leak that introduces air into the coolant. You will also make a total mess if you run straight water instead of coolant.

It sounds like your going to need another radiator and some serious flushing to the system when it's changed. Use some flush chemicals to loosen things up first and then flush it thoroughly. Remove the thermostat during flushing and then put it back in. You won't be able to save the radiator so plan on replacing that.

Response From upmm019

Ok, I ordered a replacement radiator.

In regards to flushing, do you purpose any specific type of solution that will loosen things up?

What is the benefit of removing the thermostat? Also, is there any danger in having it removed during this flush process?

I've heard that you can get air into the cooling system if not flushed right, is this true? If so, how can I avoid from having this happen?

Lastly, what is the best coolant to put back into the system. I know it had dexcool and then whent the motor was swapped out the garage put something else in that is not green and it is not dexcool either...

Response From Hammer Time

Just purchase a name brand flushing additive. Removing the thermostat first will allow the coolant to move around more and faster so it flushes better. Don't worry about the air until your refilling it with coolant. We use a vacuum fill to remove all air.

Response From upmm019

well, for those folks like me who do not have the vacuum filler... how does one refill and insure there is no air trapped in the sysem?

Response From Hammer Time

Look for a bleeder first. If it doesn't have one, then fill it, close the system, drive it around the block and run it until the fans come on. Shut it off and let it cool all the way down. Top it off and run it again until the fan cycles twice. Check the level one more time when cooled all the way and you should be good.

Response From upmm019

so what sort of coolant should I buy?

I should have the radiator on Saturday. Barring any troubles I hope to have it installed the same day.

However, not sure if I should put dexcool in it or go with something else.

it had dexcool and then when the motor was swapped out the garage doing the work put something else in that is not dexcool and its not the green stuff either.

any suggestions.

Response From Hammer Time

It's really not that important. Dexcool is a 5 year coolant and the green stuff is a 2 year coolant. The yellow stuff is a substitute for Dexcool with all the same properties as Dexcool but if green coolant contaminates either of the 5 years coolants, they just become 2 year coolants, regardless of the color. If your were to use Dexcool, you would have to thoroughly flush all the other coolants out first for it to do any good.

Response From upmm019

Well, I got the new radiator but did not get a chance to install it.

However, my son who drives this car, indicated that on his way back to college driving normal highway speeds without the air conditioning on says the car runs at about 250 degrees.

is that not a little too warm? We were only having mild 70's temp in our area too.

My other vehicles run around 210

Response From Hammer Time

Of course that's too hot but why are you driving it when you haven't installed the radiator yet? Your going to end up with a blown head gasket. That engine is very prone to that and that temp can easily do that. 230 is acceptable. 250 is not.

Response From upmm019

didnt have time.

I was not aware it would do that.

I will advise him to continue to run the heat/air to keep the temp down.

next time he is home I'll swap out the radiator.

How does one test if the fans are coming on at the right temp? I know the fans come on when the air is on and they do come on when it's not on but not until the car is around that 250 range.

Response From Hammer Time

Turning the heat on isn't going to save your engine. All that does is add a couple quarts more coolant into the mix but it only a momentary relief.

Don't worry about the fans right now. They have no effect at highway speeds.

Response From upmm019

I'm going to work on the car later today....

Just so I'm clear ... you suggest that I pull the thermostat and hook everything back up but add a flush addiative.

Let it run and then go ahead and empty everything and replace the radiator with the new one.

I can use the normal dexcool as a replacement and just run it a few cycles to insure the system is full.

That said... what should I be seeing for temps?

should I put a new thermostat in it too or can I use the existing.. it was new just a few months ago when the engine was replaced.

Also... on that temp guage where should I see it normally run? if it's working right should it ever go over the 4th tick mark closest to 260 ?

Response From Hammer Time

If the car has been real hot since the thermostat was installed, then replace it again. sounds like you understand everything. Normal temps would be 195 to 205 at cruising speed and as high as about 230 in traffic with the A/C off.

Response From upmm019

No, I think it's ran hot since we've had it.

I was trying to find a picture of what the coolant looked like before I had it flushed once...

The nearest I could find is this one..


it was not that bad but there was globs of stuff in it... just wonder if that fowled up the current radiator...

Also, do I need to buy one of thos prestone flush kits or I just do what you suggested (take out thermostat and run with addiative)?

Response From Hammer Time

Yes, all that stuff has to be flushed out.
Remove the thermostat and put the empty housing back on. Use some strong flushing chemical and run the car for at least 30 minutes @ 2000RPM if it will do that without overheating. If not, you may have to repeat the process again.

When your finished flushing, remove the lower hose and upper hose and run the garden hose into the upper until it flows clear at the bottom with the engine off.. Then put your T-stat back in and replace the radiator. Don't install the new rad until you get all that junk out.

Response From upmm019

Gotcha!

Thanks for all of your help

I'll report the outcome...

Response From upmm019 Top Rated Answer

I forgot to ask one thing....

since I am replacing the radiator.... should I replace the radiator cap too?

Not sure if that is needed or not or what sort of problem come from a bad radiator cap if there is any...

Response From Hammer Time

I try to change them when I can, especially when they get all gummed up. They are calibrated to a specific pressure for release and they have to remain accurate.

Question From cazadarojoe12123 on 2004 Pontiac Grand Prix GT V6 overheating

My car keeps overheating if I dont have the heater on. The radiator fan works. Can someone help

Response From Hammer Time

The first thing you need to do is fill the system and pressure test it for any leaks.

Response From cazadarojoe12123

Do you mean to fill the radiator

Response From Hammer Time

I mean fill the entire system to remove all air.

Response From cazadarojoe12123

Any other ideas please help

Response From Hammer Time

There are no other ideas. You were advised to pressure test the system and you have not done that.

Response From cazadarojoe12123

How do I pressure test it.

Response From Hammer Time

You can rent or purchase a pressure tester but it is becoming increasingly obvious that this diagnosis is likely beyond your abilities and you probably should bring it into a reputable shop for diagnosis.

Response From Hammer Time

OK, stop posting nonsense and stop posting to old threads.

Response From dntchke

start the car... let it run to hot. feel the motor to radiator , radiator hose. If its cold, put a new thermostat. if its hot do the pressure testing so you don't jerk a bunch of your time away chasing the rabbit down the hole

Response From cazadarojoe12123 Top Rated Answer

The car was not hot when I opened the radiator cap. The car had been sitting for at least a day.

Response From cazadarojoe12123

Okay so when I pop the hood, I noticed that the overflow was full and when I open the cap to the radiator, the fluid started coming out.

Question From vhoneycutt on 2004 Pontiac Grand Am

Car has been running a little hot, about 220-230, higher if stuck in traffic. Replaced tstat, sensor, radiator cap, fluids in December 2010. Started running hot again a couple of weeks ago, temp gets close to 240+, if traffic gets bad I have to pull over to stay out of red & now the A/C will be blowing perfect then start blowing hot air, back to cold, back to hot. Any suggestions??

Response From Hammer Time

You fan should be coming on with the A/C or when the temp hits about 225, is it?

Response From vhoneycutt Top Rated Answer

Yes, both fans running. I tried taking to a shop close to home for diagnosis, pricing and they ran the car (not drove) for 30 minutes & it never overheated, ac working perfectly. The shop is across the street from home so It didn't run long enough, I guess to get hot. As soon as I put it in drive and accelerated, the ac immediately started blowing hot & temp climbing.

Response From Hammer Time

Then you probably should pressure test the cooling system. You're probably experiencing a coolant loss somewhere.

Response From vhoneycutt

Thank you for your help. It is possible both problems are related? The place that told me they couldn't find anything also said if I had both of those issues going on that they would be separate issues??

Response From Hammer Time

They may or may not be related.

Question From bsperkins on 2002 Pontiac Montana Minivan

I have a 2002 Pontiac Montana Minivan, it has been overheating and has no interior heat. When turning on the heat, all I get is cold air. I've replaced the thermostat and flushed out the radiator and replaced with new antifreeze. The hoses seem to be ok....what now? Still no interior heat.

Response From Discretesignals Top Rated Answer

Did you pressure test the coolant system to see if there are any leaks? Do both radiator fans run? Those can be a pain to get air out of. There are a couple of bleeder screws. One is on the thermostat housing and the other on the bypass pipe going into the water pump housing. With the coolant full in the radiator, engine running, warmed up, open the bleeder on the T stat and see if you get air out. Be careful and don't over tighten the bleed screws. They snap off real easily. Feel the heater hoses and see if they are getting hot as the engine heats up.

If you keep getting air out, remove the radiator cap and watch for a steady stream of bubbles in the coolant.

Overheating Problem - So Confused

Question From Smoothgold on Overheating Problem - So Confused

I have a 2003 Pontiac Grand Prix. The other day my cars temp gauge was climbing. Every time I floored it, the temp would go back down. I would only have heat when I floored it. Every time I let off the gas, it went cold. I thought maybe my thermostat was shot or blocked. I replaced my thermostat and water pump. It is still doing it. Now I am confused and completely clueless. I thought maybe I have a blockage and would need a pressure flush. What are other ideas and options to determine what is what with my car. At the rate I'm going, I will run out of money in no time

Response From Discretesignals

Which engine?

Response From Smoothgold

3.1L

Response From Discretesignals Top Rated Answer

Those are good about trapping air and are a pain to bleed out. You might need to flush the system out including the heater core to be sure you don't have dex-sludge gumming up the works. Replace the radiator cap too if you service the system.

Before you do that remove the radiator cap with the engine cold and see what the coolant level is in the radiator. If you can get your hands on a pressure tester, make sure you don't have any leaks. Those are known for lower intake manifold gasket leaks.

Another possibility if none of that works is you could have combustion gases leaking into the coolant system causing those symptoms.

Response From Smoothgold

Def doesn't sound easy or cheap. I will have to contact a mechanic tomorrow and see if they can look at it for me so I at least know what's what. I do want to add a couple of things for general knowledge regarding this topic. I did just replace the engine september 2011. I paid extra for a low mileage engine. When I had it put in last year, it only had 30,000 miles. Also, I do have that brown sludge in the engine. Its always stuck to the radiator cap and coating the shaft every time I take it off. I contacted a radiator guy and he told me that sometimes when you swap an engine out, it gets like that. The car itself has 160,000 miles. Also I did just have the coolant system pressure flushed by a professional who has been in the business for a very long time. I don't know if any of these things help or change anything. I'm just putting it out there in case it does
