My last mechanical project was to swap out my old water pump and t-stat with new ones. After installing everything and running the car for 30 minutes I noticed a small amount of weepage coming from the back plate on the water pump. I assume I can just tighten the nuts around the plate but I want to know can they be easily overtorqued? I am only using a 3/8" box wrench to tighten them and I don't want to strip any threads on a brand new pump. BTW, it is an ASC replacement long water pump. Thanks.
