Fuel Injectors
Mark fuel injector(s) to indicate cylinder loca-
tion(s).
IMPORTANT: Fuel injector(s) must be installed
in the correct cylinder location(s). Use the

positioning by cylinder location. The injector infor-
mation screen of the diagnostic program displays
injector serial numbers.

ports of injectors or fuel tubes. Cover the injector
nozzle port in cylinder head to prevent contamina-
tion of combustion chamber.
