Fuel Injector
WARNING:
High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This maybe as high as 1600bar (23,200psi). 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.
