Fluids:
Coolant - Prior to 1995, all Corvettes came with GREEN coolant. Do not mix Dex-Cool with conventional green coolants, or it will cause the mixture to become jelly. It's a real mess to clean up. There are new coolants that are compatible both ways, they are ok.

Not very technical but it works.........open the drain plug on the rad,should be bottom right.Stick a hose in the filler cap and regulate it so the water in equals water coming out.Start it up and let it idle for ten minutes.Turn it off, and after it's finished draining fill it with green stuff.The block won't drain,neither will the heater,so you probably end up with a 50/50 mix.If you're not in Alaska that's probably good enough.
