Cleaning Fuel Injectors

CLEANING FUEL INJECTORS





NOTE: Before cleaning the injector recesses, seal the injector holes in the injector recesses with the appropriate pin to prevent debris from falling into the recesses and entering the motor.

1. Using a lint-free rag, wipe the cylinder head around the fuel injector.
2. Wipe out injector recesses with a lint-free cloth, then clean with a cylinder brush.
3. Clean the bottom of the cylinder recess with a round brush.
4. Blow out the recess and clean again with a lint-free cloth and cover over.
5. Perform these steps for each injector recess.

NOTE: DO NOT clean the tip of the injector with a wire brush. Use a lint-free cloth.

6. Clean injector body with a wire brush.
7. Clean injector tips with a lint-free cloth.

NOTE: Do Not apply antiseize lubricant to the injector nozzle, apply only to the injector body.

8. Grease injector body with antiseize lubricant.

NOTE: Always replace the seals that seal off the injectors at the cylinder head to the combustion chamber.
