Re: Hot Engine.
I had the same problem in my 94YJ. Does your gauge show the temp going up
then dropping back down 10-15 degrees after a while? If so it means your
thermostat is opening and closing. I replaced both my thermostat and fan
clutch and was about to replace the water pump too. Mike gave me some good
pointers and ideas so I just left it alone. Try a search or the archives
from last summer time frame for his answers to me. The temp now is a little
lower than it was before but not to worry.

Re: Hot Engine.
Here's what Mike said (Thurs, Mar 2 2006 10:29 pm)
" would check the fan clutch first. If you heat up the engine, the fan
clutch gets very stiff and will stop the fan almost instantly when the
engine shuts down. If it continues to spin when hot, it is worn out.
Once off, you should not be able to make it spin with a hard finger push
when hot.
You also might want to clean the sender's connection. It is on the top
back corner of the head with a single purple wire going to it.
