Asked by Jul 29, 2015 at 07:38 PM about the 2006 Pontiac Grand Prix GT

Question type: Maintenance & Repair

Can anyone PLEASE tell me the correct size for the freeze drain plug?  I have Googled
and can't find exact size.  Apparently the parts store in town can't figure it out either
because they have given me four different ones(several trips) and none were the correct
one!

expandable. Personally I have used several or different engines, never had one fail

I had that in there, but I don't want to replace it with that. I just want the ones without rubber.

Understood. That's reasonable...what i don't get is why the parts house can't tell you. Best of Luck.....
