I'm replacing my water pump. Do I need this O-ring, and how do I install it?

If you're repairing or replacing your water pump on a 1986–1991 Vanagon, you absolutely need this O-ring for a leak-free seal between the pipe and the water pump. After removing the old O-ring and cleaning the contact surfaces, simply lubricate this new O-ring with a bit of coolant or silicone grease, place it in the groove on the pipe, and slide the pipe carefully back into the water pump. Double-check to make sure the O-ring sits evenly before tightening everything back up. This simple step ensures reliable performance and keeps your cooling system running smoothly.
