Question about 2003 Pontiac Grand Am

1 Answer

Water pump? After my car overheated I noticed the overflow reservoir had a crack in it .I repair that then on my home from a 125 mile road trip I started hearing like a vibration in the front of the car ,it drove ok so I know it wasn't tire or steering related although when I applied brakes it seemed louder for a moment then you couldn't hear noise when car was stopped.The car ran @ 200 degrees on the way home,it was dark so I couldn't see well under the hood to see if anything.What kind of noise would it make if water pump is going out?

Hello! If you're water pump is failing, you may or may not hear anything at all. At most, you may hear a whine, or squealing noise; but more often than not you won't hear anything. The high temperature that your car is operating at is a concern and needs to be addressed ASAP, as further and much more costly damage can occur very quickly if the cooling system is operating normally. Be sure to check coolant levels, ensure that all caps are in place securely. It might be worthwhile even to have your coolant system thoroughly flushed and refilled.

The sound that you describe, and the scenarios in which you do and don't hear it - suggest to me that you have a problem with the braking system. More specifically, you likely have warped rotor(s). If your steering wheel shakes when you apply the brakes, then this will confirm this theory.
If the steering wheel isn't shaking when you brake, then the next thing I would suspect is the wheel/hub bearing assembly. When a wheel/hub bearing goes bad, you will often experience vibrations, and a sound that is best described as a growling type of noise, much like that of excessive road noise.

I hope this helps, and good luck! Thanks for using FixYa!

My 1997 camry overheated. We flushed the radiator, but noticed cracks in the reservoir. Will this be causing the issue, and will repair / repalcement stop the overheating?

The overflow tank won't cause it to overheat. If you have added radiator stop leak just replace the radiator is stopped up.

Leaking coolant after radiator replacement

If you are talking about the reservoir that hose is the overflow hose.
Its possible the shop did not release all of the air pockets from the system and some coolant came out with the air bubbles.
The tank should be about half full hot and cold.

1999 Jetta 2.0 is overheating only on trips over 20 miles of highway driving. Checked the water pump and it is fine. Seems that the water isnt circulating through the radiator to cool off, the water boils...

so there is block in the radiator. does the water overflows from radiator mouth? then you have to give your radiator to nearest radiator service centre, clean it! cost you around 50$ or something! better give the vehicle to a recognised garage and check any gasket are worn out. better make it fast, if you run your vehicle with overheat, you know what will happen! Thanks

While in my way home, I noticed sudden rise of engine temperature. The radiator water is empty.I noticed that the engine radiator has cracks arount the clipping metal. I brought my car to the nearest...

It is normal for some antifreeze move into the overflow tank when the engine cools down after it is shutoff and draw the antifreeze back into the engine when it is warmup, but if it is push antifreeze into the overflow tank and overflowing the tank then most likely the cylinder head is cracked or the headgasket is blown. You can take it to a automotive shop and have them check for hydrocarbons (exhaust gases) in the radiator.

Good luck

2002 ford taurus. Radiator overflows but, temp gauge not hot.

It could be both your thermostat and water pump, it could also be an air lock in your cooling system. One way or another, I think pressure is building up in part of the system because its not circulating properly.

When its cool, take the top off your reservoir, give the bottom hose to your radiator a good few squeezes, see if the water goes down a little, if it does, you moved something on and probably cured it.

If not, run the engine up, to get it warm and bleed off any air in the system. (Assuming there are bleed taps in the system)

If that also does nothing, I reckon its your water pump. And if your changing that, I'd suggest changing the thermostat at the same time.

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty

I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.

Overheating engine that runs very rough

Your mechanics are worthless, trying to charge you for **** you don't need. Water pump or thermostat is possible. No. If it started blowing cold that means that either you were completely out of water, or that there is a stop in the water passage way somewhere. A sticking thermostat could be it, and maybe the water pump might be going out, doubtful tho if it works sometimes. I would replace the thermostat and see if that fixes the over heating problem.

Another thing, is the timing of the motor. That will cause it to stall at a low rpm and run rough, and also can cause over heating due to it detonating. Buy/rent/borrow a timing light and hook it up to the number one cylinder spark plug wire and shine the light at the harmonic balancer on the crank and check for timing. There should be lines on the crank and the block that line up if it's timed correctly. And the air pump shouldn't be bad or need a belt (if it's still spinning) but pull a vaccum test on the motor to see what the vacuum is at. Hopefully, this has helped you. Buying a repair manual at you local auto store should help you with changing your thermostat, timing, and vacuum test as well as what the vacuum of the motor should be.

1999 Chrysler 300M overheating

I am having the same prob. on 04 300m 83,000 mi. I am a chrysler tech and another tech at my shop had the same problem a week ago. Mine started when i Was on the thruway my guage crept up to 3/4 so i kicked the heat on and it went normal. After stopping I found the water pump went and was leaking bad. I replaced the waterpump timing belt and tensioner pulley. thought it was good untill on a long trip. Noticed temp goin up no leaks this time, coolant full. doesnt overheat with heater on. Actuated fans with DRB3 and both work and are working when car says its overheating. Replaced thermostat and bleed system. thought it was ok untill drove 35mi. suspecting bad wiring plugged radiator or coolant temp sensor. Still driving with heat on low to keep from overheating. any others fix this problem yet?
