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.
check or replace thermostat
Blown head gasket?
water pump. thermostat.
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.
you probably need a new radiator and get the engine back flushed while your at it.
Temp sensor not working, cooling fan not working, blown head gasket.
Heater core (radiator) needs to be cleaned or changed
more than likely you need a new radiator for it, when you install it back flush the engine.
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.
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 didn't say anything about changing the thermostat....and when you changed the head gasket did you have the head checked for cracks....But first, be sure that the fan comes on and maybe back-flush the radiator. AND when you fill it with coolant be sure to get all the air out.
Type your answer here... IF WE CHANGED ONLY COOLING FAN THEN IT WILL BE OVERHEAT BECAUSE WE DON'T CHANGE OR FLUSHING OF RADIATOR. WE CAN REMOVE THERMOSTAT VALVE ALSO MAY BE HOSE PIPE WILL BE BEND
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.
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?
No an overheating engine will be due to leaking coolant, a faulty radiator, a faulty water pump, lack of oil or oil that needs to be changed
Check the grille on the front of the radiator and be sure that it is clean of all mud and debris otherwise the radiator is not able to pull air through to cool the water. You can clean that grille by removing the radiator from the truck and lightly pressure washing it.
The radiator could be plugged or a couple of the internal coolant passages in the engine block could be plugged. Try back-flushing the radiator and the engine and see if that helps.
Hi have you checked the radiator for blockage if it is blowing water back out the radiator this could be the problem.
the fan can be installed backwards and moving the air through the radiator in the wrong direction.The radiator or cooling ports can be plugged if a stop leak has been used on the engine.the water pump might not be working.
It is very common for the impeller of a VW to break apart. The result is engine overheating and no heat. Usually, the the radiator remains full unless severe overheating causes a boilover and consequent loss of coolant. Also expect that the engine becomes hot yet radiator and heater hoses remain cool. If this happens, replace the water pump. It is usually convenient to replace the timing belt at this time.
You may have the thermostat in upside down, typically you want the pointed side facing UP.
chances are that you have a blockage somewhere heater core radiator heater hose try flushing the system first then go from there
if it's like my V8 Porsche 914, i had air pockets in the cooling system at the water pump. when air is at the water pump there is nothing to push water. Therefore overheating. Other things to check is water pump and radiator.
