Water Pump Gasket SBC

The water pump gasket for small block Chevy engines is an essential sealing component that prevents coolant leaks at the water pump mounting interface. This MAHLE ORIGINAL composite gasket is designed for mechanics and engine builders who demand OEM-quality reliability during cooling system assembly or rebuild work. Whether you're performing routine maintenance, replacing a failed water pump, or executing a complete engine overhaul, this gasket ensures a watertight seal that protects your engine from costly overheating and internal corrosion.

Manufactured by MAHLE ORIGINAL under the CLEVITE brand, this composite gasket combines advanced material engineering with precision die-cutting to deliver consistent sealing performance across repeated thermal cycles. The composite construction provides superior compressibility and recovery compared to traditional cork gaskets, maintaining a tight seal even as aluminum and cast iron expand and contract with engine temperature fluctuations. At just 0.04 lbs, the gasket's lightweight profile fits seamlessly into the OEM water pump cavity without requiring any modification to mounting surfaces or bolt torque specifications.

Small block Chevy engine enthusiasts—from street rod builders to vintage race teams—rely on MAHLE gaskets to eliminate coolant seepage around the water pump. This gasket suits any SBC application, including 283, 307, 327, 350, and 400 cubic inch variants commonly found in Chevrolet passenger cars, trucks, and performance builds. Install this gasket with a light coat of assembly lube on both sides, torque the water pump bolts evenly to manufacturer specification, and verify a dry engine bay after the first heat cycle. Single gasket per package; one is required per water pump assembly.
