1995 Grangam Pont. with a Quad4 eng

The car is a a little slow to start other wias runs goog. The problen i have is when i turn the heat on the car runa hot. I turn the heat off and it cools down. Any sugestions.

Isn’t that what is expected? Or, is your reference to the engine temperature indicator increases when the cabin heat blower is turned on, and when the cabin heat selector is switched off, the engine temperature indication lowers? Is someone not expressing him/herself clearly?

Assuming you mean the engine temperature is running hot, how do you know it is running hot?
