What would cause 1994 cadillac deville engine overheating I changed the thermostat coolant temp sensor radiator and water pump. when i removed number 4 cyl plug it was orange?

water pump. thermostat.

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.

Maybe check both electical fans between radiator and engine.

you probably need a new radiator and get the engine back flushed while your at it.

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.

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.

Heater core (radiator) needs to be cleaned or changed

my 2001 ford windstar is still overheating even though i changed out the thermostat. what could it be?

check or replace thermostat

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?

it is a hyndai that's why it is a hyndai that's why

The thermostat on a 2004 Chevy Venture is changed by draining the radiator, removing the upper radiator hose, and unbolting the thermostat housing. The old thermostat and gasket can then be removed and replaced.

If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.

The thermostat on a 1992 Ford F250 7.3 Diesel is changed by draining the radiator, removing the upper radiator hose, and unbolting the radiator housing. The thermostat can then be removed, a new gasket put in place, and the new thermostat installed.

My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.

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.

The thermostat on a 2005 Chevy Equinox is changed by draining the radiator, removing the upper radiator hose, and unbolting the radiator housing. The old thermostat can then be removed, a new gasket installed, and the housing bolted down.

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.

Make sure water has not entered the oil it will be milky in color.did you bleed the system. I made two little hoes on the side of thermostat to remove air in system
