Good To Know

Q: Why do factory coolant flanges fail over time? A: Constant exposure to extreme heat and cold causes the plastic in original flanges to become brittle and eventually crack, leading to slow or sudden coolant leaks.

Q: Should I replace the seal along with the flange? A: Always install a new O-ring or seal when replacing the coolant flange to ensure a completely leak-free connection.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
