Question During the last California heat wave I was driving home with the AC on high,
and my '05 Wrangler spewed coolant out the overflow and down the side of
the vehicle. I never noticed the heat gauge going much above 210. It did this
same thing last summer ('07) on a trip to Oregon going through a very hot
Redding. At that time I got to Oregon and replaced the thermostat just in
case. It hadn't done it since, but I hadn't been in a situation where I was
running fast at freeway speeds, in high temp. (95 degrees or higher) and was
running the AC on full. I found a TSB Bulletin # 1801404 on a google search -
but can't get the website to come up that speaks to it. One last thing, when I
got home and parked it continued to gurgle a bit in the radiator or hoses.
Any help anyone can give me before I take it to the shop would be
appreciated.
