Lt1 cooling hiccup
Thanks for any help.
How is the gas gauge incorrect? Always full? Always empty?
Because it has a reverse cooling system would my method have no affect.

The behavior you describe of the fuel gauge is fairly characteristic of the fuel gauge on these cars but not to the extent you mention. shbox.com has a couple good diagnostics you can try.
Pouring the coolant in slowly and shaking is not the correct way to get the air out. Check the guide I posted. LT1s aren't typical.

But, I feel bad for you if you bleed your system every time you add coolant; you are wasting your time.
I understand they aren't typical, that's why I brought up the reverse cooling system.

I haven't had to add coolant to my car in 3 years - sounds like you're adding it frequently so I would try and figure out why you're losing coolant.

The only thing I can't find reasonable is that I've been driving the car a while after doing the water pump(changing the fluid). And then this randomly happens, the wierd thing is that the fluid is forced out of the resivoir prior to the temp gauge moving.
The only reason I'm losing coolant is because of this problem.
