A lack of water in your cooling system will cause your 2002 Pontiac Sunfire to overheat. A malfunctioning thermostat can also cause it to overheat.
Assuming it did not overheat before you replaced thermostat and water pump you may have installed the thermostat backwards. It is also possible the cooling system wasn't refilled properly and was air bound.
A 1991 Subaru Impreza might overheat because of a leaking cooling system or because of a damaged thermostat. You might also have a damaged or leaking radiator or a cooling fan that is not working.
water pump or cooling fans or thermostat low coolant
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
The thermostat in a 1996 VW Golf is located by following the lower large hose of the radiator. Before removing the thermostat be sure to drain the cooling system.
You could have a stuck thermostat or your cooling fans aren't working.
Stuck thermostat, clogged radiator.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
There are several things that can cause your cooling system to overheat. The next thing you should check is the thermostat. A blown head gasket can also cause the system to overheat.
You could have a bad thermostat, just because its new doesn't mean its good, TRUST ME ON THAT, or you could possible have an air pocket in the cooling system.
lack of coolant . no cooling fan operation, low engine oil, improper coolant mixture, thermostat stuck, debri on radiator , restriction in cooling system.
might be the thermostat stuck shut The radiator and cooling system could be low on coolant
Inoperative cooling fan(s) Bad thermostat Bad fan switch sending unit Bad fan relay Blocked radiator cooling tubes (internally)
If there is no cooling system, the engin will overheat.
The sensor on the thermostat housing is a cooling fan switch. Cooling fan switch closes the circuit to engage the cooling fan(s) when the optimum temperature is reached. When not replaced, cooling system fans will either remain continually "on" or not function causing the engine to overheat, internal engine damage and/or temperature light illumination.
yes. but there are several other things that can cause it to overheat. not enough coolant, bad belt, radiator blocked, bad thermostat,bad water pump to name a few.
you need to burp the cooling system
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.
No. If the A/C is not working there is a problem related to the A/C system. A thermostat is in the cooling system and if its not working properly the vehicle can overheat or not get warm enough to give you heat inside the vehicle.
It can be many things. Thermostat stuck, low of coolant, cooling fan not functioning properly (bad clutch), defective water pump, or a blown head gasket.
Possibly a clogged or restricted radiator Low coolant Cooling fan not working Thermostat not opening fully
BAd radiator cap, low coolant or (leaking), Bad thermostat, cooling fans not turning on.
my guess is the thermostat if you just replaced the thermostat then it might be an air pocket in the cooling system solved by taking the cap off the overflow tank squeezing the radiator hose going to the thermostat housing until the water pressure opens the hose in your hand this forces your thermostat open. if you decide to replace the thermostat yourself do the same as above to make sure all air is out of your cooling system.
There is insufficient airflow for cooling
