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

6. Clean injector body with a wire brush.
7. Clean injector tips with a non-woven cloth.

NOTE: Do Not apply antiseize lubricant to the injector nozzle area.

8. Grease injector body with anti seize lubricant.

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