Subject: What are specs of ‘cooling system connector’? I am trying to fit this to my truck, but I need to rethread the hole it fits into because the hole is corroded and I had to extract old connector, piece by piece. Correct me if I’m wrong, but the thread diameter is 0.5 in. I just need to know the thread pitch, if you don’t mind. Thank you        -HoustonHouston M.Mar 18, 2024
