So I got a 05 trd offroad 4.0
Last weekend I was wheeling and it was around 90* outside . I turn on the ac then the temp gauge shot up pretty high . I stopped cranked the heat rolled down the windows and stood outside for 5 minutes . Temp came back down to normal operating temp . Continued the day without using the ac and the truck didn't overheat .
While normal street driving I can use the ac and it doesn't overheat and the ac is cold like it should be .
Things I've checked .
Coolant is full .
Belt is good
Ac compressor was replaced when I bought the truck at 40k I now have 100k on it .
Anyone have any ideas . Or things to check ?
