Coolant drain question..

[Vette73]

Figured I would throw this one out there..

Sending out the plenum and injector housings for porting soon..

I heard you have to drain some of the coolant first...Did not get a chance to give it a really good look, but is there a petcock screw on the bottom of the radiator?

I'm sure there is the car is a 91.....Is it easy to access? Will it be visible when I get underneath the car? How much should I drain?

Thank you...

If you feel around for it then use a pair of pliers to open you dont even have to jack up the car.

Looking now....Does it look like a regular petcock screw? Reall don't see it right now....

Yep, nothing fancy. Should be pretty visible from underneath, not too much hunting around.
