try replacing the radiator cap, because it has a pressure release valve that can stick or take out your thermostat altogether, sometimes it runs better without it in the summer only. . HOW IS THE CONDITON OF THE RADIATOR? THERE COULD BE SOME CROSS TUBES THAT ARE CLOGED UP TOWARD THE BOTTOM THAT CAN NOT BEE SEEN. I TEST THIS BY PLACING MY HAND ON THE FACE OF THE RADIATOR AND TRY TO FIND COOL SPOTS.
No thermostat, no coolant, no waterpump. Basically you have no coolant circulating.
Waterpump, thermostat, radiator, radiator hoses.
Bad waterpump, stuck thermostat, bad electric fan, or a plugged radiator.
Would need to know if car was overheating before waterpump and thermostat was replaced.
Low coolant, failed waterpump, stuck thermostat, missing belt, inoperative fan, plugged radiator.
Thermostat could be at the tempure setiting, No antiboil antifreeze coolant, and the water leakage or a bad waterpump.
Check to make sure the cooling fans are coming on. Possible stuck thermostat, bad rad or waterpump. They are also well known for head gasket leaks.
i have replace the thermostat, checked the fans,filled with water and it is still overheating. Very often, the waterpump leaks and stops working only years after it was last replaced. Coolant is probably not flowing from the engine to the radiator to be cooled.
Under the waterpump.
Thermostat is the whole water outlet on the waterpump.
No coolant in engine, Blown head gaskect, failed waterpump, cracked head or block. It's not a thermostat stuck closed, you'd have heat.
On my 93 the thermostat is behind the water pump. If you remove the waterpump you will see the thermostat.
