Sorry, that's the bit I worried about. I think it might be a 10mm since 3/8 works out to 9.53 mm and that's loose.

I have this info at home, but I believe the drain was a 13mm, and the fill was a 10mm. I bought them both for around $5 each. Will confirm and update tonight with this info.

OK, I had the right sizes above, 10mm square drive for the fill plug, 13mm square drive for the drain plug. Both are male square sockets.

I was able to find the 13mm one at the local NAPA Auto Parts, but they had to special order it in. Part # S38SQDP13M, 'Oil Drain Plug Socket, Square'. They did NOT have a 10mm version Male, they only had listed a Female square socket. After some looking, I was able to find the 10mm Male at the local PEP Boys in stock, Part # 2037, described as 'CTA 10mm Square Drain Plug Socket'.

PEP Boys had theirs for $5.99, NAPA had theirs for $7.99.

NAPA, Part # S38SQDP13M


PEP Boys, Part # 2037



If you are doing this work yourself, PLEASE DO NOT use your 3/8 and 1/2 inch socket wrench for these plugs! You WILL round out the holes because the sizes are not an exact match, the holes are both slightly larger than these wrenches. It might work once, maybe twice, but eventually you'll just spin the thing and be screwed.

This reminds me, next time I'm at the local salvage yard I need to score an extra set of these plugs as a backup, now that I have the right tools to remove them.

Thank you so much for confirming the size. No, I'm not going to use the 3/8ths drive as while just playing with it a bit I could see were it was starting to mess up the plug. I'll use those P/N to find the right part. Of course finding stuff like that quickly seems to be a bigger challenge up here. Free health care? No problem. Car parts/tools overnight? Forgetaboutit!
