I replaced the water pump on my 350 chevy small block with a new water pump and the thing is leaking out of the lower bolt hole on the passenger side. I was told to remove the bolt and coat it with permatex hi tack gasket sealer and reinstall it Any how I'm wondering why there would be a leak there in the first place, any ideas?
i would try getting a new gasket and make sure you seal it really good and make sure the bolts are tightened really good
Remove the new pump and gasket. Reclean the steel surface and remove any pieces of the old gasket that might still be attached. That surface needs to be perfect. Apply the recommended sealer after this is done . Either a sealer or anti-sieze compound should be added to the threads. Recheck surface of new pump for any flaws and reinstall. Bolt in a criss -cross pattern and tighten equally , partially tight first and then all of them fully tight.
