Oh and I'm not sure if I told you this or not, BUT my recommendation for the four long bolts that go through the water pump and timing cover is to coat the threads of course with RTV, AND the bolt shafts as well. Where the bolts fo into the timing cover, they are dissimilar metals and will corrode to the inside of the timing cover and break off the next time you replace the water pump. I normally coat the threads on ALL the timing cover bolts as well as the shafts of the long ones, because it both seals and keeps the bolts from seizing making them easier to remove next time. A lot of people look down on RTV like that, but as long as it's used sparingly and in the right places, it's good stuff.
