Coolant Drain Procedure
My 2007 GXP turned 5 late last November so the coolant needs changed. I've been waiting for better weather to do it myself. I've seen the thread on how to fill the system but nothing on how to drain it. Is there a petcock on the radiator, are there drain plugs in the block? Can anyone give me some help please?
