Re: 92 Jeep Cherokee overheats at idle...

Wow thanks for all the responses. Stupid thing still overheats. After some investigation I belive that there is not enough air circulating through the engine compartment. Reason: My wife was delivering mail, she called and said it was alright at 220-230. I asked her to put th electric fans on. (Hard wired - a switch controls them.) Almost instantly the car jumped up to 250. (yes the fans are installed the right way.) So I think next I am going to raise the back of the hood and inch or so and see what it does.

Other notes:

Belt is correct...
Checked fluid with car raised in front - fine
radiator fluid does boil
Installed second temp gauge (1. so she can she while she is driving on the right side 2. The cars temp gauge was off +20 and yes car still overheats)

Question: How to do test the fan clutch. On the internet I found two ways:
1. Rotate the fan.... if working it should not rotate all the way around
2. When fan is on I placed a piece of cardboard in the way and the fan did not hesitate to knock it out of my fingers... (This is not a reccomended method...)

Anyothers?

Thanks again everyone....

Chris
