Yes, lets talk about heat, my vette has never overheated, even when the water wasnt full.
But whats got me stumped is why does it run hotter on the freeway than in traffic?
Yes, even after a freeway run, getting back into traffik makes the needle back off.
I don't think its a grounding problem btw, its always done this, even after I took a direct cable from the battery and grounded the guages.
