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.

1996 mazda 626 overheats after shur off and sometimes driving. no smoke


sounds like a restricted radiator.. the thermostat has 2 x jobs to maintain the temperature and to restrict the flow-so by removing the thermostat you actually went backwards- meaning the coolant will flow to fast thru the radiator and will not have time to be cooled down prior to returning to the engine block. since your heater helps to cool it down my guess(educated) would be a restricted radiator..

1998 toyota rav 4 that keeps overheating. I just replaced the thermostat


Thermostat may be installed upside down...this can cause overheat.
To test your engine...if you don't think thermostat is faulty, remove the thermostat.
This is sometimes called "running cold"...and it should not overheat. If it does, you have bigger problem than thermostat.
You can test thermostat too by placing it in hot water thats not quite boiling and see if its opening properly.

Hope this helps...

MY JETTA 2000 OVERHEATS BUT THE TEMPREATURE REMAIN CONSTANT WHAT IS THE SOLUTION


Your temperature thermostat determines how hot the coolant should get on your car. These thermostats are about $15 at the auto store. They are prone to failure over time and will definitely fail if the engine overheats. The hardest part of changing the thermostat is removing the lower nut where the thermostat is housed... its in an awkward position and you will need a universal joint socket to remove it.

Check the new thermostat by putting it in a pan of water and bringing it to a low boil. See that it opens. It is possible to get bad parts off the shelf.

Need help locating the thermostat on a 1999 ford taurus station wagon.


Where the upper radiator hose attaches to the engine is the thermostat housing. Remove the hose from the housing. Remove the housing, the thermostat will come out with the housing. Be careful to orient the new thermostat exactly the same as the old. If the new thermostat is put in backwards the car will overheat.
Hope this is helpful.

2004 Jeep wrangler 4.0 - 6cyl overheating


I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.
