IT could have an exaust leak somewhere or if it has an electric cooling fan the fan could be bad, short in it wiring or blown fuse Is your aquastat working? Is the radiator clogged up with sediment? If it has overheated before, is the head warped? Your question is a lot of questions. Take the radiator cap off with the radiator full and gun the engine while it's still cool. If the water runs over when you gun it, the head, or the headgasket, is history, Or the block or head may be cracked. Take it to your mechanic for a free evaluation and an estimate. You may be better off getting another car and trading that one in, and let the dealer deal with it. They can afford it.
water pump. thermostat.
Blown head gasket?
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
Remove the Radiator and have it serviced if they are able to. If not you will need to replace it, would be a good time to replace the Radiator hose's as well. Hope This Helps.
If your 1995 Oldsmobile Aurora keeps overheating and the issue is not the thermostat or the water pump, it could be the cooling fan. It might also be the radiator (leaking) or the hoses between the engine and radiator, or the shroud could be clogged or damaged.
You may have the thermostat in upside down, typically you want the pointed side facing UP.
If it's overheating, it cold be thermostat, radiator or possibly other problems. If it's not overheating it could be the coolant level sensor.
The most common cause of overheating is a thermostat stuck in the closed position. However, other causes are: faulty water pump, clogged radiator, clogged hose(s), coolant leak or a broken drive belt. I had a 1987 legend with around 160K that was overheating. Antifreeze would boil out of the overflow. I changed my radiator and it fixed the problem.
more than likely you need a new radiator for it, when you install it back flush the engine.
my 2001 ford windstar is still overheating even though i changed out the thermostat. what could it be?
Radiator plugged or restricted? Cooling system airbound? Water pump not circulating coolant? Radiator cap defective? Radiator hoses collapsing under pressure? Defective gauge/cooling temperature sensor?
