WJ still overheating

I did all the steps that you guys had told me to try and it fixed it but not completely. I flushed the fluid, put a new thermostat in it, and put in a new fan relay switch. I still overheat though. Not badly just gets a little hot and will cool back down when i start moving again. It loses a little bit of fluid here and there and doesnt seem to be getting into the oil. Any thoughts on what it could be?

how badly is badly? Stock 4.0L run 210 to 215 e-fan kicks on at 220

or could have air in the system.

mechanical fan clutch could also be bad.

If the fan is not working cause of relays.... and you wanna stop dealing with the pain of replacing fan relays 50 bucks a pop. I installed a switch and have step by step thread of how i did it. My jeep is free of any issues.

sounds like a fan issue...the highway air cools it down...so its pointing to the fan... maybe try and wire it up manually, thats how i have mine setup and its great.

Yeh, but if his fan is coming on it may not be pulling enough air through. Maybe install a mechanical fan/clutch combo. I know the electric fan here in Vegas doesn't work worth a crap when its 100+ outside.

Could be a bad fan motor. I recently changed mine and took the old one apart. I had four brushes in the motor but one was worn down so much that it was not touching the stator. My fan would come on, but not spin fast enough to cool the engine.

If you don't have time to do it right the first time, how do you have time to do it over.

I had the exact same problem. The fan was spinning but not fast enough to move air through the radiator and the car would overheat in traffic. Replaced the fan motor 2 years ago and the temp needle has never moved past dead center since. When the fan kicks on now you can feel the hot air being drawn through the radiator.

I believe these bad fan motors are drawing too much current and either frying the relays and burning up the plug that connects to the relay.

It doesn't overheat all the time just everyonce and a while. Someone told me it was the head gasket or the heater core. Would that be a idea?

Does it happen when you stop at a light? or sit idling in traffic?

No not usally. It hasn't done that since I replaced the fan relay switch
