hey i have a 95 lt1. i wana drain the radiator. my question is how do i drain the overflow tank? or does it all drain when i drain the radiator

 

It drains th whole thing
Ive replaced my radiator before
and when i flushed it the radiator was empty


96 z28-bolt ons:
Magnaflow exhaust,(no cats) LT Pacesetter headers, ORY,MSD ignition 6AL, stall converter 2800, and some suspension work.

 

I would just pull the overflow tank out, because this will allow you to flush it out a lot better then if it were still in the car.

To pull it out you will have to pull your battery out. Then there is a single 13 or 15mm bolt holding the tank in. Pull the tank out and unhook the hose that goes back to the radiator. This is very easy to do.
