Thermostat failures My car keeps overheating

Hello Patricia,

I would suspect the following items:
Coolant level too low or loss of coolant
Water Pump failure
Thermostat failure
Temperature sensor

Check these items and report back for assistance.

possible headgasket failure allowing coolant to be burned in combustion chamber. air in coolant system can also cause overheating. failed thermostat can cause overheating...a lot of possiblities

This is the primary cause of engine overheating. Possible leak points include hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs, automatic transmission oil cooler, cylinder heads and block. Perform a pressure test.

their are other factors besides the water pump that cause overheating --recheck installation for correct operation ---other factors --clogged dirty radiator-cooling fan non operation- thermostat failure-hose failure --air bound

check coolant level your vehicle is overheating and trying to protect itself need to look and check reason for problem before more damage is done --look for leaks water pump failure -thermostat failure --

Thermostat could be stuck closed - put your hand on the hoses (after the engine has been running a bit) and check if one is cold. If one is cool to the touch - the water pump has failed - or the thermostat is failed (stuck) shut (supposed to fail open).

Radiator fans inoperable - check the fuse and relay.

Head gasket failure - would need to be checked via piston pressure check.

BELOW list is compiled from our staff with a more likely cause of overheating.

Radiator cap failure. Must be able to handle 15 psi tested.
Antifreeze failure. Has the coolant been tested or changed in the last few years?
Does the cooling fan cycle?
Clogged radiator.
Thermostat
failure. Thermostat's do fail, you you have any memory of changing it?
Head gasket. This problum you would tend to never be able to get the air out of the radiator, lots of small bubbles. if this is your problem seek provisional help this problem only get worse not better.

Hope these tips guide you to the solution to your problem

It sounds like your thermostat has gone bad and sticking close, Replace the Thermostat and Antifreeze. When replacing the thermostat, buy a fail safe thermostat so you will not have a overheating problem when the thermostat fails. Good luck and hope this helps. Keep me posted, be glad to help.

just installed a new water pump and thermostat my 97 trans am keeps overheating,anyone know why?
