Aftermarket temp guage fluxuates way up and down, from 120 to 230, any ideas?
The car has a serpentine belt system, and I have a theory that it might be slipping on the water pump pulley...any other ideas?? the water is full....its starting to **** me off. It'll be 150 all day, then suddenly it'll just go up to 230 for NO reason no matter what kind of driving I'm doing. Its not the guage..its an Autometer mechanical guage.

There's no replacement for displacement!

Air in the system(sometimes hard to get rid of)
Bad thermostat(I've seen new ones that are bad)
colapsed lower radiator hose
When did it start doing this?

definetaly sounds like your thermostat is sticking occasionaly.
if you don't feel like replacing your thermostat, you can just replace the engine with a ZZ4 crate engine and see if it stops doing that..
