Calling DrBuick

DrBuick I have a favor to ask of you....

I just changed the oil on my cat and I didn't think of this until after so I never measured.

I'm thinking of replacing the oil cooler drain plug with a Fumoto valve or EZ Drain next time I change the oil.

Next time you have a cat in the shop for an oil change would you mind measuring the size and thread pitch of the oil cooler drain plug please.

Thank you! For your trouble I'll ask Tammie to text you some pictures of her cat.

Sure, I actually just added the valve, L adapter and a secondary lock (just a clamp) to my cart from a site that sells the EZ Drain but then I decided to hold off. I want to verify the size before ordering. Otherwise I'll end up with $50 worth of stuff that I can use or return by the time I do my next change.

If folks are confident that TallCool1 measurements are correct I can write it up now. I'm just not sure if he got the info. from a reference somewhere or actually measured the drain plug himself... I'd prefer the latter to be sure. Maybe he will see this since I tagged him and chime in.
Oil cooler is 12x1.75 1 inch long

Oil pan is 14x1.5 3/4 inch long both from seal to end of plug
SRC... Double check me but I think my measures are pretty close to what Dak59RT lists on the magnetic drain plugs. Let me know if you see different if it would affect magnetic plug selection different don't think so but keep me honest tks. And tks Dak59RT a(nd Dr. B. I did rely on his data as well...)
