Fuel Injector: Removal
WARNING:
High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This maybe as high as 1600 bar (23,200 psi). Use extreme caution when inspecting for high-pressure fuel leaks. Fuel under this amount of pressure can penetrate skin causing personal injury or death. Inspect high-pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system.
CAUTION:
PAY CLOSE ATTENTION TO THE FOLLOWING POINTS WHEN REMOVING FUEL INJECTORS:
- Injectors MUST be removed only using the special tools provided for this purpose.
- Injectors MUST NOT be disassembled.
- Before cleaning injector recesses, seal all injector holes in the injector recesses with a pin.
- Clean all injector recesses in the cylinder head with a non-woven cloth and then a cylinder brush.
- Carefully clean sealing surfaces of injector recesses with the round brush. DO NOT us a power brush.
