The Rubber Moulding Water Pump Gasket (21103569 / 22658275) provides a precision leak-free seal for water pump installations on Volvo D13 and Mack MP8 engines. This molded rubber gasket seals the water pump housing to the engine block, preventing coolant leaks that lead to overheating and engine damage. Always replace the water pump gasket whenever servicing the water pump — reusing an old gasket is a leading cause of repeat coolant leaks. ZTech manufactures this gasket to OEM dimensional specifications.

Q: Which engines does this gasket fit?
A: Fits Volvo D13 and Mack MP8 engines. Replaces OEM part numbers 21103569 and 22658275.

Q: When should this gasket be replaced?
A: Replace any time the water pump is removed for service. Never reuse an old gasket — new gaskets are inexpensive insurance against repeat leaks.

Q: What is included with this gasket?
A: Includes the rubber moulding water pump gasket(s) required for installation on D13/MP8 engines.

Q: Is this OEM or aftermarket?
A: Aftermarket replacement manufactured to match OEM dimensions and rubber compound specifications.

Q: Can a leaking water pump gasket cause engine damage?
A: Yes. Even a small coolant leak at the water pump gasket, if ignored, leads to coolant loss, overheating, and potential head gasket failure.
