Maintenance Instructions
• Pay attention to the hose ends and contact points that
will typically show early signs of hose failure. Observe
the area around all hoses for signs of leakage.
• Synthetic rubber can oxidize and harden over time.
Squeeze the hose to make sure it is pliable. Entire hose
length should have a consistent feel and appearance.
• Many times hoses will fail from the inside. A hose
that appears to be in good condition can fail due to
deterioration of the inner hose and reinforcement. This
type of deterioration can sometimes be detected during
pressure testing.
• Cracks, blisters, or splits in the hose outer cover are the
most visible signs of hose failure.
• Pressure test complete heater and cooling system
annually.
Test should be completed while performing
hose inspection to allow all hoses to be observed for
bulges and leaks.
Upon completion of the inspection process, reinstall all
protective covers and closeout panels to original condition.
Many factors influence hose life such as location, years in
service and service environment.
Heater and coolant hose
replacement is recommended after 5 years of service. In the
event a hose failure is experienced prior to the recommended
replacement time frame, age and condition of remaining hoses
should be considered to determine if all engine and body hoses
should be replaced to reduce the potential for additional failures.
Engine Oil
NOTE: Use only recommended viscosity engine oil. Refer to
the Engine Operation and Maintenance Manual for specific
engine oil specifications.
The PSI 8.8L gasoline engine requires the use of synthetic
blend oil that meets Dexos1
® standards. This requirement will
provide a reduction in volatility and oil consumption, significant
wear protection, and improved piston cleanliness.
Meeting
the Dexos1 ® standard can also enhance aeration control
for improved fuel efficiency while providing better oxidation
properties.
SAE Oil Viscosity Grades
NOTE: An optional plug in oil heater is available if the engine
is being operated in conditions that may require a cold start
assist.
It is required that the Dexos1
®
oil meet SAE 5W-30 viscosity
standards. This oil weight will be used regardless of ambient
temperature.
Fuel System
WARNING
To prevent personal injury and / or death, or
property damage, always wear safety glasses
and protective gloves when dealing with fuel
system components.
