Tips replacing the water pump

When you're replacing the water pump, a little sealant on the water pump where the main gasket goes will prevent said gasket from slipping when you jockey the water pump onto the engine. I inadvertantly ripped a gasket by not doing this and had to do the whole job over again.

First bolt the water inlet flange onto the new water pump, using the new gasket that came with the pump. Tighten to 14-19 ft-lbs. Then position the water pump against the engine opening with the other new gasket in place, while at the same time ensuring that the o-ring on the right slips into the other side of the flange. Push the flange against the o-ring to seat it as much as possible. By now you should be able to bolt the water pump back into place. Torque to 14-19 ft-lbs. By tightening the water pump to the block, the o-ring will end up in the right place. Double check it to be sure.
