hey, I have a problem , hope some of you guys may have seen this before.
I did search the millions of old threads and came up with alot of info, but nothing sounded like what i have going on.
Xj 92, 4.0
2inch rubicon lift with 30 in maxxis.
the problem.
last fall at highway speed my temp neared red line, i shut it down and after an hour everything was ok, and it never overheated again,
during the winter i did notice thet the heater was cooler than normal, but i'm ok with that, but i did buy a new thermostat.
yesterday, same exact thing after about an hour of normal highway driving it got hot, i shut it down and everything was fine for the rest of the day.
so last night i replaced the thermostat, and figured that was that,
today i load up and get about 30 miles from home nice temp then WHAM. it spiked, so i let it cool. but this time it overheated again, so i shut it down, played this game all night, finally got it home.
my guess is water pump, but before this there has never been a drop of leakage. can a pump go bad and not leak?
any ideas, suggestions welcomed .
thanks.
