SBF 289-351W Thermostat Housing Gasket

The SBF 289-351W Thermostat Housing Gasket by SCE GASKETS is a precision-engineered sealing component designed for Small Block Ford engines, specifically those equipped with 289 or 351W displacement platforms. This water neck gasket serves as the critical seal between the thermostat housing and engine block, preventing coolant leakage and maintaining proper cooling system integrity. Whether you're rebuilding a classic muscle car, restoring a vintage pickup, or maintaining high-performance street equipment, a reliable thermostat housing gasket is essential for reliable operation and longevity.

Manufactured from composite material at a precise 0.031-inch thickness, this gasket provides optimal compressibility and durability under the thermal cycling and pressure conditions typical of active engine operation. The composite construction delivers superior sealing performance compared to traditional paper gaskets while maintaining excellent chemical resistance to modern coolant formulations. The engineered thickness ensures proper sealing force distribution across the mating surfaces without over-compression, reducing the risk of gasket failure and coolant weeping. SCE GASKETS' manufacturing precision guarantees consistent dimensions and material quality across every unit.

This gasket is ideal for engine builders, restoration specialists, and enthusiasts performing cooling system service or engine rebuilds on Small Block Ford platforms spanning the 289 cubic inch and 351 Windsor generation engines. Installation is straightforward during thermostat housing removal—simply position the gasket between the water neck and engine block before reassembly. The compact 5.75 x 7.65-inch profile fits standard Small Block Ford thermostat housing configurations. One gasket is included per order, though many builders stock multiples for complete cooling system restoration or fleet maintenance applications.
