MK667318
Exhaust Gas Recirculation Equip Washer
Mitsubishi FUSO®

The Exhaust Gas Recirculation Equip Washer, also known as part number MK667318, is a small but crucial component of the truck's exhaust system. This washer is designed to create a tight seal between the EGR valve and the engine block, preventing any exhaust gases from leaking out. The EGR system is responsible for recirculating some of the engine's exhaust gases back into the intake manifold, which helps to reduce emissions and improve fuel efficiency. Without a properly functioning washer, the EGR system may not be able to operate efficiently, leading to increased emissions and reduced performance. Therefore, it is important to ensure that this component is in good condition and replaced if necessary during routine maintenance.
