Hi guys....I need a quick answer on this one....thanks. Do our car's have a radiator petcock or just pull the lower hose and make a mess? This is my first GN thermostat swap and I hear they can be a pain so if anyone has any quick tips they would be appreciated. Thanks
Gary
I have one on my 84 T-Type !
I have one on my 87GN. On the very bottom, directly below the filler cap.
Yes, there is one where Shawn says. Also, be careful on the re-installation of the retainer bolt on the thermostat housing. The intake is aluminum and it needs to go in straight or you can strip the threads. Just thought ya might want to know that.
