I have an '03 TJ Sport with the 6-cyl. When I run the A/C, it runs a little hotter than normal, which I consider to be reasonable. However, sometimes when decelerating from freeway speeds, such as coming down an exit ramp, the temperature will spike to where it says the engine is overheating. Then, it will come back to normal within a couple of minutes of driving.

I recently had the dealership replace a blown water pump...

Any ideas on what might be causing this weirdness? Anyone else having this problem?

when I bought my 97 a year ago I noticed the water temp to be over aveage when using a/c but it never overheated I thought maybe gauge isn't accurate. anyway it turn out to be the themistat was sticking a little I had that changed and now it has not gone over 210 I hope this helps...

I have a 03 sport with A/C also,I will check it out .

Sounds like a flakey thermostat, which would possibly cause damage to water pumps. Perhaps even a blockage elsewhere. You're still under warrenty, go have it checked out and verified, you've paid for it.

Thanks. I knew somebody here would know something about this!
