Having problems with your 2004 Jeep Wrangler ?

2004 Jeep wrangler 4.0 - 6cyl overheating

\015 My 2004 jeep wrangler was overheating, so I replace the thermostat...thought there might have been a leak in my radiator but it turned out to be just a faulty radiator cap...however with the new thermostat the engine still overheats...when I remove the thermostat completely the engine runs perfectly fine at normal temperature...could have been just a faulty thermostat...should I try installing a new thermostat once again? Any insight would be helpful\015 Posted / edited by AnonymousUser on : 16-04-2018

Answers :

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.
Try replacing the radiator fan relay
