Lube oil is routed from the front of the oil cooler cover
to the back where it enters the oil cooler. Lube oil is
cooled as it flows from the back of the oil cooler to the
front into the oil filter housing.
• If the oil cooler is restricted, a bypass valve in the
oil filter base will open and allow oil to bypass the
oil cooler going directly to the oil filter housing.
Oil flows to the oil filter element. Oil passes through
the outside of the element to the inside of the element,
down the stand pipe, back into the oil filter base, and
into the oil cooler base.
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
