Inspect the OEM harness for good connections.
Inspect the condition of the OEM harness.
The electronics grounding studs must have a wire
ground to the battery. Tighten the electronics
grounding studs at every oil change. Ground wires
and straps should be combined at engine grounds.
All grounds should be tight and free of corrosion.
• Clean the electronics grounding studs and the
terminals for the ground strap with a clean cloth.
• If the connections are corroded, clean the
connections with a solution of baking soda and
water.
• Keep the electronics grounding studs and the
strap clean and coated with MPGM grease or
petroleum jelly.

Contact with high pressure fuel may cause fluid
penetration and burn hazards. High pressure fuel
spray may cause a fire hazard. Failure to follow
these inspection, maintenance and service in-
structions may cause personal injury or death.
If you inspect the engine in operation, always use the
proper inspection procedure in order to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, “General hazard Information”.
Inspect all hoses for leaks that are caused by the
following conditions:
• Cracking
• Softness
• Loose clamps
Replace hoses that are cracked or soft. Tighten any
loose clamps.
Check for the following conditions:
• End fittings that are damaged or leaking
• Outer covering that is chafed or cut
• Exposed wire that is used for reinforcement
• Outer covering that is ballooning locally
• Flexible part of the hose that is kinked or crushed
• Armoring that is embedded in the outer covering
A constant torque hose clamp can be used in place
of any standard hose clamp. Ensure that the constant
torque hose clamp is the same size as the standard
clamp.
Due to extreme temperature changes, the hose will
harden. Hardening of the hoses will cause hose
clamps to loosen. This hardening can result in leaks.
A constant torque hose clamp will help to prevent
loose hose clamps.
Each installation application can be different. The
differences depend on the following factors:
• Type of hose
• Type of fitting material
• Anticipated expansion and contraction of the hose
• Anticipated expansion and contraction of the
fittings
Replace the Hoses and the Clamps
Refer to the OEM information for further information
on removing and replacing fuel hoses (if equipped).
The following text describes a typical method of
replacing coolant hoses. Refer to the OEM
information for further information on the coolant
system and the hoses for the coolant system.
