• High Quality Material: This product is made from two materials: aluminum and silicone. The aluminum is hard and offers excellent structural stability, maintaining the gasket's overall flatness and rigidity, and resisting deformation during installation and use. The silicone is soft and features good elasticity and flexibility, allowing it to adapt to subtle changes in the contact surface.
• Application: This product has an inner diameter of 1.88 inches and an overall width of 4.1 inches. It is suitable for SBC and BBC engines and is compatible with a wide range of vehicle models, including engines with displacements of 265, 283, 305, 327, 350, 383, 396, 400, 427, 454, 472, and 500 cubic inches.
• Easy Installation: First, turn off the vehicle's engine and wait for it to cool completely to room temperature. Align this gasket with the mounting holes on the housing and place it gently. Adjust the gasket's position so that it is perfectly aligned with the contact surfaces of the housing and the engine block. After confirming that the holes are properly aligned, slowly reinstall the thermostat housing and evenly tighten the mounting bolts.
• Prevents Leaks: This product effectively prevents coolant leaks. When installed between the thermostat housing and the engine block, the silicone sealing layer tightly adheres to both contact surfaces under installation pressure, filling microscopic gaps and preventing coolant from seeping out. The seal also prevents air from entering the coolant circulation system.
• Reusable: This product offers excellent reusability. It does not need to be discarded after routine maintenance and disassembly. The overall structure is resistant to damage and deformation, allowing it to be reused for subsequent installations after disassembly. As long as the product remains intact with no visible damage, it can be stored for future use and will maintain good performance even after multiple installation cycles.
