Engine Cooling and Lubrication
The cooling system consists of the following
components:
• Gear-driven water pump
• Water temperature regulators
• Gear-driven oil pump (rotor type)
• Oil cooler
The engine lubricating oil is supplied by a gear-driven
pump. The lubrication oil is cooled and filtered.
Bypass valves provide unrestricted flow of lubrication
oil to the engine parts when oil viscosity is high.
Bypass valves can also provide unrestricted flow of
lubrication oil to the engine parts if the oil filter
element should become plugged.
Engine efficiency, efficiency of emission controls, and
engine performance depend on adherence to proper
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to this Operation and Maintenance
Manual for more information.
