All you guys keep forgetting one of the most basic problems with the

Pantera cooling system.  For many years as the Master Mechanic of POCA, I

talked, talked, and talked about this (and solved dozens of overheating

problems in Vegas).  The neck on the pressure tank on the Pantera is longer

than an American radiator.  The pressure cap does not hold as much pressure

as it is labeled when new, and with 1 year of use (especially since the

tanks are backward from the way they should be, so we check the water in

the pressure tank instead of the overflow) the seal deteriorate to the

point that it does not hold enough (or any) pressure.  Install a NEW cap

every spring.  Use a cap somewhat higher than stock (18 psi rating is a

good compromise).  This is usually the problem when temperatures are O.K.

on the freeway, but tend to "puke" when coming off.



Don't forget, highway overheating (real, not stock gauge readings) indicate

a radiator, water pump, or the infamous wrong thermostat), and idle or

traffic overheating indicates fan problems.  Cleavelands should use ONLY

192 degree thermostats (160 degree doesn't solve any problems, only delays

them, causes loss of power and wear).  AND DO NOT BELIEVE THE STOCK GAUGE!

Also, water is the most efficient coolant, so if you do not need antifreeze

use water with anti rust additive.
