Extra Coolant Passage On New Head
I just installed a remanned head from Clearwater Cylinder, and as I was filling it up, coolant started to flow out of this port (see picture).
I already sent back the old head, So I can't check it to see if There was a plug on the old one or not.
my question is, does anyone know the thread size for that so rhat i can get the right plug for it.
oh yeah, im new to the forums.
thanks

That's strange - looks like the port for the temperature sending unit, but they did away with that after 96 and the 0331 heads weren't used until 99 at the earliest.
