    here is the way i bleed the system of air, take a floor jack and raise the front of the car as high as possible, then fill the coolant recovery tank up and run the engine until it reaches just short of overheating, about 2/3 scale on the temp gauge, then shut it off and run a hose over the radiator, the air will self bleed and the coolant will be sucked in from the tank, works everytime.

My 97 jeep wrangler 4.0 is overheating badly,waterpump,thermostat,radiator,clutchfan have all been changed,and no mixing of water and oil what could it be? Also not air locked

do a compression test on cooling system just because no oil and water mix doesnt mean head gasket good ---keep an eye on fluid level possible can be burning the coolant also check flow new doesnt mean free from defects or improper installation [thermostat-water pump]

How do you properly bleed the coolant system on a 1994 Toyota Celica 1.8 stx?

If even possible, it sounds as though your water
pump is not turning the right way

It isn't even moving any water & that is all
you worked on, unless the thermostat somehow
could go in backwards

Even after replacing the radiator, thermostat and

The problem with overheat is due to poor coolant circulating. The main culprit is the Radiator. When the radiator is clogging up, coolant can't be circulating. The stagnant coolant inside the engine water jacket keeps absorb heat from combustion chambers having no way to dissipate the heat then the engine is overheated. You can test the water pump by removing the thermostat, then hooking everything back. Open the radiator cap, then turn on the engine to see if water flowing down to several small tubes inside the radiator. If water can't go down fast enough to cause over flow at radiator opening then your 90 Legend Radiator already got clogged up. Replace with a new radiator, not even a rebuilt one. Good luck.

1990 mercury cougar keeps overheating have replaced radiator and thermostat and problem is still happening. waterpump is not making a noise any suggestions Wayne

Get your radiator cap checked and if replacing use the one for a overflow tank. If the cap pressure was okay then you want to look at water circulation in the radiator. After the thermostat opens you should see flow inside the radiator. If it does not circulate the block is clogged or the water pump is bad.

Finally, if you have an electric cooling fan there are relays and some have two fan speeds. Autozone may be able to diagnose your problem.

Replace cooling fan termstat and vehicle still over heats

Thermostat

Test thermostat in a jug and pour boiling water on it , it should compress meaning it works. Check that the waterpunp is operating pushing water into the engine .Check that radiator water flows to the watrpump. Is tension of fanbelt of waterpump sufficient that it doenst slip. Lastly check that the radiator fan is working if has a electric fan. if this doesn’t help check if radiator or engine water passages isn’t blocked.
