Excessive RTV that seeps into the contact area with the coolant will eventually break off and clog radiator and heater core passages, reducing engine cooling and heater operation.

While water pump and water outlet gaskets are trending toward molded rubber designs, some of these gaskets are paper. Paper is still a reliable choice and Fel-Pro proprietary Blue Stripe® paper gaskets provide effective sealing solutions Without properly venting the air out of the seal chamber area, the mechanical seal seals air, not cool water. This is a dry-running condition that generates heat and quickly degrades the materials at the sealing interface. A common environmental control used in vertical applications is a recirculation line from the seal chamber to pump suction. Many gaskets today feature a metal core (usually aluminum) with a computer-printed sealing bead placed on each side. The sealing beads generally consist of an elastomer or silicone material. The metal core serves as a platform for the sealing beads, and aids in preventing over-tightening, since the metal core acts as a stopper layer
