Fitment questions
Which part number should I match?
Start with 21122541 / 20499419 / 21475228. These numbers identify the intended reference family; they do not establish compatibility with every engine or truck carrying the same model name.
What should I check before ordering?
Compare the installed part number, engine serial number (ESN) or VIN, mounting points, ports and physical design with the photos and details above. For service kits, also compare the contents and the parent assembly. Contact WIHMCCK for fitment help before ordering if any detail differs.
Vehicle and OE brand names identify the intended application. This is an aftermarket replacement; it is not represented as a genuine part from the vehicle or OE manufacturer.
