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.
