C4 Radiator Flush & Clean Process
I am a new Forum member and have a question for anyone who can help me. I need to flush the original anti-freeze from my '89 C4. I have searched for drain plugs in the block and cannot find them. Any suggestion as to how a cooing system flush and clean is done? Regards, Sam :confused:

Sam I usually use the prestone back flush on my 89 and all my cars or you can bring it in to have it profesionally done, also if your doing this it is a wise thought to remove the radiator and clean it out I do this bi yearly YOU will be surprised at the garbage you find in there
