Default Too many issues
So my father and I have replaced the distributor in my 1994 Corvette (thank you everyone that helped with that) and now the engine is running crazy hot, 270 to 300 degrees hot. Quite literally immediately after replacing the distributor. We checked the codes and by the Haynes manual it says that our distributor is still causing issues, that our "coolant sensor circuit" needed to be checked and replaced, and that the "right bank oxygen sensor circuit" must also be checked and replaced. All these issues emerging now seems to me a bit suspicious. What are your thoughts on this? Has anyone else experienced similar issues? Both me and my father are new to Corvettes, and we would really appreciate the help

Thank you everyone,
Brody Paulk

By releasing the valve on the thermostat housing?

Releasing valve is one method. Another is hold rpms up , 1500 rpm and open radiator fill tank by windshield and keep adding coolant as radiator /engine burps air out

Also, the coolant sensor in the water pump, ensure its not broken. Very easy to do when doing opti replacement

IMPORTANT: Start this with a cold engine, not anywhere near warm. On a hot engine, taking the radiator cap off will spew coolant all over, in a hotter-than-boiling state and burn you. Make it a habit to check the radiator hose before looking at the cap!

Good call, Sometimes we assume people have a basic common sense knowledge of mechanics.

Very true. I broke mine when I did this job. Very easy is an understatement, I basically looked at the old one and it broke.
