Re: Overheating problem '97 TJ
Jerry and Mike are right. That said, I usually run somewhat "stronger"
coolant, in case there is a loss and I have to limp home after putting some
Dasani or Evian in it. The best place to store extra coolant, is in the
cooling system.

So do I, but know that it will not cool as efficiently, and it may
actually freeze. But you can run 240 with a fifteen pound cap, if you're
on the razors edge as my siamese small block four hundred, with Corvette
four core.

Re: Overheating problem '97 TJ
I dont know if this is related but my brother-in-laws TJ will read hot from
time to time and the oil gauge will go to near zero and the fuel gauge will
screw up by showing about half what is actually in there. His problems
sounds electrical to me but I have not checked it out yet. Be interested in
finding out what is wrong with yours. My 01 TJ overheated after I rearended
a Dodge truck and pushed the shroud into the fan! Ha Ha
