you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.
a fuse or a bad fan motor
Check the coolant fan see if it turns on when the engine gets hot. if not then your temp sensor could be bad
check your radiator. is it clean or does it need to be replaced? a simple cleaning cured my problem.
you need to check cooling fans with ac on
My guess is the head gasket, have same problem. Nightmare
If it overheats at speed, but cools down when you slow down, the problem is likely a head gasket. Combustion gasses are leaking into the cooling system, adding bubbles (which take the place of coolant) and extra heat. Slowing down means the engine is spinning slower, and less combustion gas gets into the cooling system.
maybe its u or da car
The air conditioning is a separate system from the cooling system and will not be affected by overheating, however if the overheating problem is associated with an inoperative cooling fan or a blockage in the air flow through the radiator and evaporator then the system will not cool properly.
are the cooling fans coming on
The best place I've found to get your brakes replaced is the local muffler man. Any type of smaller garage in your area will be able to take care of your brake problem at a fraction of the cost of taking it to the Pontiac dealership.
High pressure tells me of a possible head gasket problem. Have the cooling system pressure tested by a reputable garage; this will answer some questions.
dose the electric fan run if not check the relay if it runs check the water pump
changing the valve cover gasket will not fix an over heating problem u need to check out the cooling system. Radiator, water pump, hoses, belts
had the same problem with a sibring,took to the garage,they replaced the thermostat and gasket and found a hairline crack in the thermostat housing they replaced the housing and everything was fine then
Cooling fan is bad, draw's current but will not turn so it overheats. It will eventually melt down. This happened on my 95 GT. I have another 95 GT with the same problem. Replace the main cooling fan. The one on the left or drivers side.
it is probably your water pump
I just had that same problem..I took it in to have it fixed and they replaced the blower motor resistor and that seems to have fixed the problem
there is a Senior that kick it the fans on it is located under the throttle body or it might be the primary fan is bad and only the second fan is working
Sounds like your cooling fan relay is shot. Ron J.
sorry i cant answer that ? but just curious I have a 2003 Pontiac grand am se and the front brakes have to be replaced about every 7 months, are you haviing any problem like that with your car?
When it's running hot you should hear the cooling fan running, if not that is your problem. If the cooling fan does not operate check the fuses, cooling fan relay, cooling fan switch and cooling fan motor. One of them is at fault.
if the pump and thermostat have been replaced on a 2001 malibu and it overheats and the heat doesnt work now but the air does. do it need bleeding still , will air in the line still cause that problem...
You may have to replace the cooling fan relay or the cooling fan itself, I had the same problem and I first replaced the relay and it helped but then the cooling fan went out and I repalced it and now everything is fine.
