Is the radiator petcock right hand thread?

Post by sportfan » Thu Jul 22, 2021 8:18 pm

Like most people I had to pull the lower hose to drain the antifreeze. I could only turn the plug a quarter turn and never got it to come out. I just wanted to be sure I had it back in right. Does anyone know what size oring it takes ?

Never had an issue draining the coolant using the plug on the radiator. I turn it anti-clockwise to open, usually with a pair of pliers to grab the tab. I've never pulled it all the way out so never noticed an o-ring. My biggest issue is that I nearly always forget to close it again before I put coolant back in......
