Application Details

This injector sleeve is used in diesel fuel system repair where the injector bore must seal correctly against combustion pressure and coolant passages. When the sleeve is worn, damaged, or not sealing properly, combustion gas or coolant can enter the fuel system and contribute to misfire, injector damage, and hard-running conditions.

This part cross-references Ford OE number 8C3Z9N951A for the same application.

Common Issues It May Address

Installation Notes

Replace the sleeve during injector service or injector replacement to help restore proper sealing at the cylinder head. Clean the injector bore and surrounding surfaces before installation, and verify the bore is free of damage or contamination that could affect the seal. Confirm vehicle application by year, make, and model before ordering Part Number 522-045.
