Overheating problem '97 TJ
I was idling in traffic on the 4th waiting to get into parking at the new
Heinz Field in Pittsburgh for fireworks and all of a sudden my temp jumped
up to just below the red and the 'check gauges' light came on. I did a
quick u=turn and got into a non-congested lane and got moving to get some
air flowing and it calmed down to a little over 210, but just a hair higher
than usual. I was running the a/c on max since i had the top on still.
Shortly after it cooled back down to a more reasonable level I noticed
another strange problem....when I came to a stop the oil pressure would dive
down to zero and the light would come on again. Once it cooled down for
good after parking for awhile this went away too. It's done it a few more
times since and it's usually during slow driving with the a/c on. The oil
level seems fine and it's Valvoline full synthetic 10w30. Coolant is topped
off and is a nice green color, not nasty stuff.
Any theories for this happening?

Hi Endo,
I'd flush your system like you've doing every two years to avoid
the electrolysis that'll eat the head gasket, water pump seal, and core
plugs. And go ahead and replace the fan clutch.
The oil temperature lags behind the water, but eventually catches
up, if you had checked it you would have seen it with the constancy of
water, with about the same lubricating qualities. If your going to get
caught in traffic jams, then switch to 20/40, or 20/50 like I use at
three hundred thousand miles. Remember pickups with the trailer package
also have oil coolers.

Re: Overheating problem '97 TJ
The fan clutch sounds probable, and I will probably flush it too just to be
safe but the antifreeze in it is only about a year old and still nice and
green. Maybe it's too strong a mixture and I need more water.I will get a
bottle of the Redline Water Wetter too just to help out.
I will consider a heavier weight oil also, i'm due for a change now anyway.
Too bad Wally-World only carries Valvoline full synthetic in 10w30 so i'm
going to have to go to a 'real' parts store like Auto Zone. (sic)

Re: Overheating problem '97 TJ
The fan clutch sounds probable, and I will probably flush it too just to be
safe but the antifreeze in it is only about a year old and still nice and
green. Maybe it's too strong a mixture and I need more water.I will get a
bottle of the Redline Water Wetter too just to help out.
I will consider a heavier weight oil also, i'm due for a change now anyway.
Too bad Wally-World only carries Valvoline full synthetic in 10w30 so i'm
going to have to go to a 'real' parts store like Auto Zone. (sic)

Re: Overheating problem '97 TJ
Get the thermo activated clutch, the centrifugal saves gas, but
will over heat at high revolutions per minute, below forty miles an
hours like we do in the lower gears off road.
