Engine Oil; Sae Oil Viscosity Grades; Fuel System - IC Bus CE Series Operation And Maintenance Manual

Maintenance
• Many times hoses will fail from the inside. A good-looking
hose 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.
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 LPG engine requires the use of synthetic blend
oil that meets Dexos1 ® standards.

Heater and coolant hose
This requirement will
provide a reduction in volatility and oil consumption, significant
wear protection, and improved piston cleanliness.
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
standards. This oil weight will be used regardless of ambient
temperature.

Fuel System

To prevent property damage, personal injury,
and / or death, never loosen fittings or vent any
propane. Escaping propane can cause frostbite
and severe freeze burns. Wear insulated PVC
rubber gloves resistant to propane, goggles
for protection against accidental release of
pressurized products, and thermal protective
clothing when handling refrigerated liquids.
