Cometic Renault Clio 16V 1.8L/2.0L 84.5mm .036 inch MLS-5 Head Gasket (F4P/F4R Motor)

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically made for Renault Clio models with the 1.8L or 2.0L F4P and F4R engines. It has a bore size of 84.5mm and a compressed thickness of 0.036 inches. A head gasket is crucial because it seals the combustion chambers, preventing coolant and oil from mixing with the fuel and air, and also keeps combustion gases from escaping into the cooling system.

Cometic builds these gaskets with multiple layers of stainless steel for strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and different surface finishes, even with aluminum heads on cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.036 inches on this particular gasket. These MLS gaskets are designed to seal well without needing any extra sealants.
