Good To Know

Q: Do I need to drain the coolant first? A: Yes, drain the cooling system before removing the pump housing, then refill and bleed the system once the new seals are seated.

Q: Can a worn seal damage the engine? A: Coolant weeping past the seal can drop the coolant level and lead to overheating, so replacing the seal kit promptly protects the engine.

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