Doing some work on my car, wanted to drain all coolant completely. I was told to remove plug rear left side of engine to better drain engine block. Misplaced plug. No one seems to know what size it is. Thanks for any help.

Hi,

My manual doesn't provide thread pitch or diameter. However, I think (please know I'm doing this from memory), it is an M14x1.5 pitch. If possible, get a cheap bolt with those specs and confirm it fits.

Let me know if that helps.
