Description of Change: A new torque specification is now used on C27 and C32 engines. The new torque specification is for the cap nuts on the fuel injector. The new torque specification will better secure the wiring harness to the fuel injector.

Adaptable To: The old torque specification for the cap nuts was 1.7 ± 0.25 N·m (15 ± 2 lb in). The new torque specification is 2.5 ± 0.25 N·m (22 ± 2 lb in). The new torque specification is adaptable to all the above serial numbers.
