Reply to "Overheating"

Back in the early '90s (I think) HRM did a story on street blowers and the significance here is, the dual-Magnussen system only put out 6-8 psi in their test, so your heating problem may not be only from this 87-lb power-adder.

One sequence is, the 45-yr-old overflow system springs an air leak that does NOT leak water as its not always under pressure. Heat from running expands the coolant and the extra makes its way into the big overflow tank. When the engine cools down, instead of sucking the squeezed-out coolant back into the motor, it sucks air and the coolant stays in the tank. A couple of sessions like this and you're low on coolant with no external leaks. A second 'fail' involves the surge-tank pressure cap not sealing on the normally-rough Euro tank neck base (the one you can reach), which is slightly too long for U.S radiator caps. The usual fix for this is to take the small tank to a rad shop and have a U.S rad neck soldered on, with a new U.S cap. Your Pantera probably needs a thorough look-over by someone who's familiar with the beast's cooling system. Good luck- J Deryke
