[DeTomaso] Overheating Issue

[Charles Engles]

Dear Will,


         Given that it used to run cool and he didn't have problems *after*
opening the cooling system which could have introduced air bubbles, I would
say that this scenario sounds frightening like Jim Gray's trials and
tribulations with his cooling system.   Jim went through *all* the logical
steps: fans, radiator, new water pumps, new thermostats, etc.   He
ultimately bought some cooling system pressure tester and went through it's
diagnostic steps.  Step two seemed to indicate that he had a bad head
gasket, which had been suspected for some time.

        Jim bit the bullet and proceeded to pull his heads.  The passenger
side had suspicious rust on the deck and gasket.  After the machine shop
cleaned the heads and inspected them, they were pronounced junk scrap with
evidence of a previous crack repaired with a weld and evidence for a new
crack.  

        I am sure that Jim will chime in with his first hand account and
opinion on this cooling problem, which seems to be in the head or gasket
given all the problems that he has eliminated from the list.


               Warmest regards,  Chuck Engles

Hey Guys.
A friend is at his wits end with the cooling system on his  Pantera.
Up until a year ago, his car ran cool (160 hwy and 180 city). It then slowly
started to run hotter and hotter ( 230
city).
So he replaced the rad (fluidyne), pump(elelbrock, dual suckers and new
tubes. Things didn"t change. 160 on the hiwaya
nd 230 in the city. He then installed a HD Robershaw 180. Same thing except
it ran 180 hwy and 230 in the city.
He has jacked the back and front up numerous times trying to get any air
out. He's about to pull an "Elvis" and shoot
the thing.
Any suggestions? Asajay, didn't you go through this a while ago?
Will
