LUBRICATION SYSTEM
Oil Cooler Housing and Oil Filter Base
• The oil cooler cover, oil filter base, and oil
filter adapter all contain passages that
direct the flow of oil. In addition, the oil
cooler cover and the oil filter base both
contain passages that direct the flow
of coolant.
• Oil is routed from a passage in the
crankcase to the oil cooler cover inlet
where oil is directed rearward to the oil
cooler. Oil flows through the cooler and is
then directed through the oil filter adapter.
Oil passes through the filter and down the
standpipe, then back to the oil filter base
where it's directed to the reservoir and the
main oil galleries. Coolant is directed from
a passage in the crankcase to the to the
cooler cover. Coolant passes through the
oil cooler and exits at the EGR cooler
supply port.
• The oil filter adapter mounts the oil
pressure switch and the oil temperature
sensor, and feeds oil to the turbocharger
lubrication line.

Oil Cooler
• The stacked-plate type oil cooler is
mounted to the bottom of the oil cooler
cover. When the cooler cover is set in
place on the crankcase, the cooler sets in
the high-pressure oil reservoir. The water
pump circulates coolant through the
cooler to remove excess heat from the
engine oil.
• The coolant and oil are separated by
multiple plates that create passages in the
oil cooler. The cooler cover and cooler are
not serviced as separate components.
• The volume of the reservoir, with the oil
cooler in place, is approximately one quart.
