New radiator in the Jeep

I recently had to replace the radiator in my Grand Cherokee. It was seeping, but not at the plastic end tanks... I didn't overheat yet, but it wasn't too long till it would.

I was also beginning to lose trans fluid...

I'm always amazed how much stuff costs these days. But was pleasantly surprised to find Radiators, automotive radiators, condenser, oem radiators, truck radiators. I ordered a 2 row ALL METAL radiator for just $135 delivered....

Purty, huh?

Anyway, I am going to have to look for a warmer thermostat. This new radiator seems to be running TOO cool. Almost two lines lower on my temp gauge. Problem is, I don't what temp thermostat is in there. So I need to get a real gauge on it.

With my new job, I ride in a vanpool, so I don't often get to drive my Jeep for work anymore. This week I had training away for the work place and put better than 500 miles on the Jeep. Pleasantly, even running the AC, I still managed 20.2 MPG for the last complete tank.

I HAVE managed almost 200 miles of offroad travel in the last month, and a camping trip. I really LOVE my Jeep. But then again, its not a true MPG monster... But doggone, it sure runs cool... Pretty important considering I intend to pull my tent trailer with it...

Jeep is a 95, so not OBD2 compliant. I'm the 4th or 5th owner, unknown what has been done before I bought it 4 years ago.

Just go to one of the part stores and ask them to look up the part then tell them you want the next higher temp they have.

There could be 2-3 temperature ranges listed, If memory serves it will be stamped on the thermostat itself. My guess though is probably 180F if its running too cool. I believe its supposed to have a 195F.

OEM thermostat is a 195*. The gauge in the ZJ is a real gauge (not a buffered-reading dummy gauge), and typically reasonably accurate.

If it sits right on the line below straight up (or just above it), it probably has a 180* t-stat in it.

This is sitting at the third line from the left... Gotta go two to get tostraight up... Runs plenty cool, even on a 500 mile roundtrip.
