How good is that. When I was 11 my Dad brought home a 1967 Suzuki super 80. In the back of the family station wagon, laying on its side of course.
FOR ME!
First thing I said after WOW! Was, does it run.
Well of course not.
I guess that was my start as a motor cycle mechanic.
I rode that thing all over the state. Then after turning 16. And 2 days after I got my motorcycle license I got pulled over for the first time.
And yes it was my paper route money that got me the parts to get it going. And a Father that didn't realise that I needed to be 16 to drive a motorcycle on the road. And I never did tell him. He's gone many years now. Perhaps he's looking down and grinning.

Hi Bob! Most of us run a 180 degree thermostat. I run a high flow 180 degree thermostat.
if your drain valve is broken, just pull the lower rad hose off.

All 1970 Corvettes except for the LT-1 used a 180 degree thermostat. 1970 LT-1s used a 195 degree thermostat due to the A.I.R. equipment.
Why do you feel you need to change? Chevrolet specified 210 degrees as normal operating temperature (230 degrees for heavy traffic, stop and go, and prolonged hot weather idling) in the owner’s manual… If you’re running 220 degrees and your radiator isn’t puking coolant, is a change really required?
