Coolant drain question..
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... Last edited by Vette73; 09-01-2015 at 07:42 PM.

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