Initial Check
WARNING
Wear safety glasses or a face shield, as well as
protective clothing, to prevent personal injury when
using a steam cleaner or high-pressure water.
Use a steam cleaner or high-pressure washer to clean the
engine.
A black light kit, Part Number 3163338, can be very
helpful when locating the source of an oil leak.
Add the fluorescent tracer, Part Number 3376891, before
running the engine. The tracer will be highlighted by the
black light to help identify the source of the leak.
Operate the engine until the coolant temperature reaches
82°C [180°F]. Inspect the exterior of the engine for leaking
gaskets, seals, o-rings, pipe plugs, or fittings.
NOTE: Before replacing any gaskets, check the
capscrews to make sure they are tightened to the correct
torque values. Refer to Procedure 018-009 in Section V
for capscrew torque specifications.
