Hi Matt-

 

As others suggest, the stat is the prime suspect.  Some of the aftermarket
stats these days aren't too great and don't last very long.  Try to get a
heavy duty 180 degree Stant Superstat  (NAPA 532080 or equiv.); it's worth
the extra couple bucks IMHO as it is built much better.

 

You shouldn't need to lift up the A/C compressor to get the driver's side
bolt out if everything is in its proper place.  It's a minor pain, but try
different open end wrenches (not box end) to see what fits.  I use a stubby
and it works well for me.

 

Another possibility is a bad voltage limiter on the gauge.  On my J, both
the temp and fuel gauge will rise in sync.  Nothing like gaining some extra
fuel.not.

Here's a constant temporary issue I am having....

When car is cold, from sitting all night...
It starts up fine, I warm it up for 2 minutes and then start to drive.

About 5 minutes into the drive the temperature guage begins it s ascent to
it's 
normal spot; just about a quarter of the way up from the dead cold position.

Then the needle keeps going, all the way to the HOT position, where it sits
for 
a minute...and then it creeps back down to the quarter mark.

Here is what I have done to date:
- Pulled the NEWER radiator and had it flushed
- Flushed the block out twice
- Water Pump is fairly new on the 45,000, new everything, motor
- Newer Hoses are not collapsing
- Heater core is clean and works
- I have "burped" the radiator

All I can think of is that the Thermostat is taking too long to fully open
and 
needs to be replaced??
Who's with me?
(Just a pain in having to lift up that A/C Compressor to make that change.)
Thanks!

Matt Allyn
