I have replaced my aftermarket water pump and am getting a leak from one of the seal between water pipe tubes that mate with the back side of the water pump housing and the o-rings. I have attached this a few times (4) and am getting the same leak. The pipe, after torquing the assembly to the block, appears only to butt up to the o-ring and not seat properly. I have just purchased, from the dealer, a new set of o-rings and gasket, but, in viewing the o-rings, they appear no different than those that came with the water pump. Is there something I am missing? Should I lube the o-ring with anything? Should I use gasket sealer when inserting the o-ring in the housing?
I am frustrated having done this many times over the last few weeks. There is nothing obvious as to why it's failing.
