Dart over heating???

FIRST question "how do you know" it is overheating, and please don't say "because the factory dash gauge says so."

Aftermarket thermometers are not that expensive, you can get a meat/ heating/ ac type with a probe and just tape it to the under 3/4 of the top hose, then wrap and tape some insulation or a rag over it to insulate it, then see what it is actually running for temp

Is it puking out the overflow? You know you have a good cap?

Wind up the engine and see if the bottom hose tries to suck shut. This is a sure sign of a restriction in the system

Do you have a feel for how dirty/ clean the block is?


I would agree that WITHOUT a shroud, the fan needs to be closer to the rad.

DOES IT OVERHEAT at speed/ cruise? If so, the fan is not the problem, for now.

WHERE IS the timing? Retarded timing will cause overheating.

What engine combo, etc do you have?
