Electric radiator fans? Just a guess but it could be the water thermostat. They are very inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. This is the function of the thermostat which is inline to the water pump and allows the engine to warm up before cooling through the radiator then when the fan thermostat on the radiator heats up the electric fans will run. You might be able to squeeze the upper radiator hose to feel if pressure is building up or water is flowing.

The electric radiator fan runs after truck is shut off. Will turn off after 30-40 min. Is this normal?


no it is not normal....have a repair shop check the coolant fan sending unit or the coolant fan relay...a bad sending unit maybe sending a false overheating signal to the fan causeing it to stay on or the on off fan relay maybe sticking on..an make sure the jeep is not actually running hot the temp guage maybe reading the wrong temp

1994 BMW 318i runs hot, just recently had the fan clutch and thermostat replaced and its fine. This seems to happen when I turn the AC on. I am a novice is there something I can do myself to check the air...


There should be an electric fan in front of your radiator. Check to make sure that it turns on whenever the air conditioning compressor kicks on, or whenever the car is too hot. If not, the electric fan may have failed, but the most common failure point is the relay for the electric fan.
There may be a temperature sensor in the end-tank on the radiator with a three wire plug. That is supposed to turn on the electric fan when the engine gets too hot. If you short the two hot wires to the brown ground wire with the key turned on, you can test to see if the relays work for the high and low speed settings. If the contacts have burned away in the relay, you will hear it click but the fan won't turn on. The sound will help you find the relay.

Cer runs hot newrelay&temp fan dosnot seem to


If the relay and temp fan are new, and the old ones did work but not very well. Try putting on the old ones again and see if they will even choke. If they do, then it could be your new product. The only other solution i can come up with besides that, is an electrical issue, which i know from exp. can lead to a $1500 bill... good luck

Overheating


When you mention the radiator having a hot upper in pipe and a cool bottom out pipe tells me that the coolant is not moving around the engine. This could be down to a water pump not working, blocked radiator, thermostat not opening. The bottom hose should be cooler than the top hose but once the engine is up to working temp which is around 85/90 degrees c for an audi the bottom still should be farly hot to touch. Hope this helps

Replace termostat in a 1998 chevy cavalier still run hot


Yes it does have a electric fan, mine went out on my 2003 and I just changed the electric motor itself. Autozone offered the entire fan with motor or they offered just the motor. I chose to replace the motor only because I knew the fan blades and housing was fine. I had to drop the fan down and take out the entire assembly from the bottom but overall the process was a 3 out of 10 on the difficulty.
