There are two types of engine oil cooler that can be
installed on this engine.

Engine Oil Cooler with a Low
Mounted Filter Base

Illustration 38

g01332170

Typical example

(1) Oil cooler
(2) Long setscrew
(3) Short setscrew
(4) Joint
(5) Setscrews
(6) Housing for the oil cooler
(7) Joint

Perform the following procedure in order to inspect
the engine oil cooler with the low mounted filter:

Place a container under the oil cooler in order to

collect any engine oil or coolant that drains from
the oil cooler.

Refer to Disassembly and Assembly, “Engine Oil

Cooler - Remove” for removal of the engine oil
cooler.

Thoroughly clean the oil cooler (1) and the cylinder

block.

Personal injury can result from air pressure.

Personal injury can result without following prop-
er procedure. When using pressure air, wear a
protective face shield and protective clothing.

Maximum air pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.

Inspect the oil cooler (1) for cracks and dents.

Replace the oil cooler (1) if cracks or dents exist.
Ensure that no restrictions for the flow of
lubricating oil exist in the oil cooler (1).

Dry the oil cooler (1) with low pressure air. Flush
the inside of the oil cooler (1) with clean lubricating
oil.

Refer to Disassembly and Assembly, “Engine Oil

Cooler - Install” for installation of the engine oil
cooler.

Ensure that the cooling system of the engine is

filled to the correct level. Operate the engine.

Note:

Refer to Operation And Maintenance Manual,

“Refill Capacities” for additional information.

Check for oil or coolant leakage.

Engine Oil Cooler with a High
Mounted Filter Base

Illustration 39

g01322246

Typical example

(1) Oil cooler
(2) Joint
(3) Housing for the oil cooler
(4) Nut
(5) Long setscrew
(6) Setscrew
(7) Joint

Perform the following procedure in order to inspect
the engine oil cooler with the low mounted filter:

Place a container under the oil cooler in order to

collect any engine oil or coolant that drains from
the oil cooler.
