[215 DW] OIL COOLER
ASSEMBLY
Description
The oil cooler assembly is located near the left
front of the engine. Engine coolant from the
radiator flows through the lower radiator hose,
into a chamber in the oil cooler. The coolant then
flows into the water pump.
The oil pump sends engine oil through the inlet
port of the oil cooler into the cooling chamber.
Heat from the engine oil is transferred through the
chamber walls to engine coolant. Cooled oil exits
the oil cooler through the oil outlet port, flows
through oil filters, and then into the engine.
E7 engines feature a “removable-bundle” type oil
cooler. Periodic visual inspection of the oil cooler
will indicate condition of gaskets, O-ring and core.
If a problem exists, these components can be
serviced separately rather than replaced as an
assembly.
The presence of engine oil in the engine coolant
may indicate internal engine problems or worn,
loosened or damaged parts within the oil cooler.
Continued operation under these conditions may
result in severe engine damage.
