This metal gasket seals the connection between the radiator and the exhaust system on the host tractor. It is positioned at the interface where the exhaust stream passes near the cooling system; a proper seal prevents exhaust gas leakage and maintains the thermal balance of the cooling loop. A failed gasket allows hot exhaust to escape, which can lead to localized overheating and reduced cooling efficiency. The part is manufactured to the original geometry, matching the sealing face of the mating components so no additional shimming or sealant is required. On reinstallation, clean both mating surfaces and tighten the fasteners to the specified torque.
