I've searched and searched and can't find the answer I'm looking for. Maybe starting a thread will help.....
WJ-4.7 ~21,000miles on the engine, ~213,000 on the body, ~10,000 on the tcase.
Ever since the temperature has risen (75-95 average outside temp), my temp gauge sits just above the 210 mark. It will sit and idle at this temp all day long. When I start driving, the harder I drive, the higher the temp gets. Pulling a heavy trailer, and it climbs up pretty quckly. Driving hard on the interstate will make it climb as well. (I live in "The Mountain State") There's no such thing as flat ground here, so the engine is almost always under a load.
A few months ago I replaced my fan clutch, as it locked up. About a month ago, I had the dealer replace my malfunctioning elec-fan (under TSB
), hoping that would solve my problems. When it didn't, I took the fan clutch back to advance auto parts for exchange. It's still having the temperature issue.
I'm not losing any coolant as far as I can tell, and the engine runs strong, with the exception of an occasional idling issue that I believe is just the IAC needing cleaned.
I don't know if it makes a difference, but while sitting still the A/C works great, and when driving 70 it seems to not be as cold.
