Question about 2004 Jeep Wrangler
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
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.

Yes, for the price of a thermostat and the real possibility of getting a faulty one (that won't open or won't open fully) out of the box, I'd try another one...
If it still overheats, the water pump might be a probable culprit. It might not be sending enough water flow to cool the engine. Even with the thermostat fully open, it still restricts the water flow compared to no thermostat at all... When you take it out, it might flow enough that the engine does not overheat anymore.
