Product Details
If you're working on the top end of your Lexus LX470, Toyota Tundra, or other compatible vehicles, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed to provide a strong seal between your cylinder head and engine block, which is crucial for keeping combustion pressures contained and preventing coolant and oil from mixing. This gasket is specifically for the left side of the engine.
Cometic builds these gaskets with multiple layers of stainless steel, giving them increased strength and the ability to rebound, which helps them resist corrosion and maintain a seal even under high output conditions. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.040 inches. Because they are MLS gaskets, they don't require any additional sealants, making installation more straightforward.
This gasket is suitable for use with both aluminum heads and aluminum blocks, as well as aluminum heads and cast iron blocks, as it can handle the shearing forces that can occur between different metals. It's a solid option for rebuilding or repairing your engine.
