Front Cover
• Oil flows from the crankcase to the oil pump
via a passage in the back of the front cover.
• When the oil pump is turned by the
crankshaft it creates oil pressure and
pushes oil through one of two passages.
One passage is to the oil cooler and the
other is through the oil pressure regulator
back to the oil pump inlet.
• All of the passages from the front cover to
the crankcase are sealed with a silicon in
metal, one piece gasket.
Oil Cooler
• The oil cooler is mounted in the valley of the
engine and uses engine coolant to dissipate
heat from the engine oil.
• Oil passes from the rear of the cooler to the
front, while coolant passes from the front of
the cooler to the rear.
• The coolant and oil are separated by
multiple plates that create passages in the
oil cooler.
• Note: If the oil cooler is damaged it could
cause contamination of the lubrication
and cooling systems.
Oil Cooler Housing & Filter Base
• The oil cooler housing has passages in it to
direct the flow of coolant and oil.
• Oil is routed from the front of the crankcase
to the back of the housing where it enters
the oil cooler. The oil passes from the rear of
the oil cooler to the front of the cooler and is
cooled in the process. The oil is then sent to
the oil filter through the oil filter base.
Filtered oil is sent to the oil reservoir for the
high pressure pump and the oil passages in
the crankcase.
• The coolant is directed from the front of the
crankcase to the front of the oil cooler. It
then passes through the oil cooler and cools
the oil. As the coolant exits the rear of the oil
cooler it is directed to the EGR cooler.
