Does a Toyota 2E engine (Corolla) has a Thermostat Valve? While it also have an electronic radiator fan that automatically switches ON by thermo-switch when it reaches certain temperature

you take the water pump off and visually insect pump vanes
will need a gasket
or check water pump seal isnt leaking (dripping coolant )


other causes of over heating
thermostat stuck
engine cooling fan not spinning fast enough
thermostatic fan switch faulty
soft hoses
clogged radiator

hi there . there are lots of causes. head gasket. blocked radiator.
air lock. stuck thermostat. check that your fan is actually switching
on and off. if not check the thermo switch on the engine.

Hi
Do you have a bleed valve on or around radiator / radiator pipes.
if yes the undo the valve and leave the car running till it bleed.
once its bleed, you will have full circulation of the water and both pipes will heat up also the fan will come on.

If no bleed valve then undo the water bottle or metal cap.
start the car up and leave it running till the fan kicks in. it will only kick in when the system is bled and no more air in the system.
Thanks

For many of the 90's and 2000's Toyota various models - Camry, Tacoma, 4 Runners, Corolla, and some other models it is usually caused by temperature sensitive fan switch on the radiator not operating. Electric fan on the radiator should operate when temp above 200 degrees. Less often the control relay 90987-03003 is defective. Check if bubbling in the radiator smells like exhaust. That would indicate a blown head gasket. A jumper wire from your marker light positive to the lower contact in the fan control relay socket will operate your fan when parking lights are on. The larger vehicles with more powerful radiator fans will need a hefty jumper from a headlight positive to avoid overheating the lighting wiring. Make sure the engine is off and warmed up to check the radiator core with your hand to see if it is getting circulation. If it is all cold the thermostat might be stuck.

IT IN THE GAS TANK

temperature switch. The temperature switch finishes the circuit for the cooling fan. Once the engine reaches the specified optimal temp. the switch completes the circuit and turns the cooling fan on. Hope this helps

Please solve this problem, my car COROLLA 1988 automatic 1.6 has the same problem!!!!!

Fan switch should be located in the upper radiator tank. Two wires to it. it works off the temp of the water.

If you remove thermostat water will circulate too fast and will not cool down, replace thermostat and check if your fan is turning in correct direction. Also make sure your ignition timing is ok. I found on some vehicles the waterpump seems ok but when vehicle starts heating up the impeller gets loose on the shaft. Check your brakes if they are not binding.
