1991 pontiac grand prix le 3.1l overheating


I had an older vehicle that overheated. I flushed out the radiator twice, but it was so clogged up, I had to replace it, so check the radiator. If you inspect the radiator from the filler neck, you can see if there is crud build-up on the tubes. The problem could be the water pump. Typically when water pumps fail, they start to leak from the weep hole(s) on top and /or bottom. Is there any leak from the pump? If there is, that is indication that the pump need to be replaced. Hope this helps !

My 2003 Pontiac Gran Prix overheats in zero degree weather.


Make sure radiator is full and that all hoses are ok. Then make sure that the thermostat is opening and that your water pump is circulating coolant through the radiator which must not be clogged. Till you find issue run your heater full blast with window open to add additional cooling to engine.

Overheating


Most common reason for overheating is 1. low coolent lvl 2. faulty thermostat (stuck closed). 3. Faulty water pump preventing coolent from circulating through engine.

Check coolent lvl in radiator when engine is cool by removing the cap and filling it up till you can see the coolent, replace cap and try. If you have the proper lvl of coolent. Replace your thermostat, which is located under the thermostat housing (right underneith where your top radiator hose connects). Fill with coolent and see if that helps. Next test is to start the car and let it run till it gets to normal operating temp or near (180 to 220 degrees F) Pinch your upper radiator hose and see if you can feel a gush, or flow of water rush through the hose when you release your pinch hold on the hose, (by pinch, I mean to try and totally squeeze the hose together) If you don't feel the rush of coolent through the hose, then your waterpump is faulty. If your car quits overheating, but your heater hoses don't get hot, then they are probably stopped up at the point where they connect to the engine. Its a common area for gunk, rust, and corrosion to build up.

Coolant leak 2006 pontiac grand prix


These engines like the 3.8 usually have a intake leaking problem. Also the have plastic elbows on the passengers side of intake that go to heater hoses can leak also. Is it a 3.8 liter engine in your car. And where abouts does the fluid look like its coming from.

I have a 2006 pontiac grand prix 3.8l my heat only blow cold aair I checked the thermostat and the heart inlet hose is hot but the outlet hose is luke war what could this be maybe clogged heater core.


Ok fellow 2006 Grand Prix owners!! By trial and error, I went through the process of elimination because my car would over heat and had no heat inside. After changing the thermostat, I had to replace the water pump. However, after you do this, you need to open the inlet hose bleeder and let the air out a few times. This solved my issue of overheating and I now have great heat!!!

1999 grand prix gt overheating. Changed thermostat, water pump, upper radiator hose. Please help!


does the upper and lower hoses seem to be the same temp when car begins to overheat? ore the radiator cooling fans coming on before the car overheats? did you pressure test the cooling system and radiator cap? also may want to remove the lower hose and flush the radiator. is the check engine light on and does it run bad?

1999 Pontiac Grand Prix Overheating


I had trouble with overheating on my 2000 Grand Am, The dealer could not even resolve the issue,(they wanted to replace the intake gaskets)...I knew that was not the issue, no air leaks or water leaking there; so I sit down to think; what are the causes of overheating. Thermostat sticking - nope not it, water circulates, Water leak - nope not it, has water stays until it gets too hot and goes out overflow, fans working - yep...hummmm the only other thing I could think of was losing of water pressure, yep that's it - the cap on the coolant tank was going bad, got a new cap ($8.00) replaced the old one and no more trouble going on 6 months now.

Hope this may solve your issue.

Overheating and blowing cold air. 1999 Grand Prix


It sounds like your water pump may have gone bad. The water pump pushes the antifreeze through the engine, heater core and Radiator which is regulated by the thermostate. Sorry for the bad news but i hope this helps, and Good luck
