Re: New winch = TJ Running Hot

I would stay away from anything that would increase the boiling point of coolant. Race motors are designed to handle high heat. Not so with a passenger car though - you'll run the risk of cracking the head (bad) or a water jacket (worse).

Change the t-stat to a 180 and consider adding an auxilliary fan to help with rockcrawling speeds.

If this does not help, get a removable winch cradle so you can take it off when you're not using it.

Re: New winch = TJ Running Hot

i agree with Pontiac58. if your engine is running hotter than your thermostat, a lower t-stat won't help. a 180 t-stat opens fully at 180 degrees. a 195 t-stat opens fully at 195 degrees. if your system was running at 195, then you could put a lower stat in and possibly bring it down to 180. but, since you are running hotter than your stat, i would say its either a heat transfer problem or a coolant flow problem. flushing the system is a good idea. we just did it on my brothers 93 cherokee. it had never been done before and had brown mud-like silt in the bottom of the radiator. we flushed it with a kit, then added the Super Flush luquid, drove it for a couple days and repeated. it took 2 doses of super flush and repeated flushing. its finally clean, but we'll probably do it again in the fall just to make sure. matt

Re: New winch = TJ Running Hot

Yes, the 4.0 always ran around 210. It is not boiling over. I was just concerned with damage or loss of performance with the higher temp. I will have to admit that the day I noticed the higher temp. was very hot and I had the Jeep loaded with alot of gear. Thank you for all of the input. I think I will go with the hi-flow thermostat (195) and possibly look into an aux. fan if there is any boilover problems offroad. With living in the Northwest, we only have a few months that have 80+ degree temps. So, I hope it won't be a problem. Thanks again.
