Perform the following procedure in order to inspect
the engine oil cooler:
1. Place a container under the oil cooler in order to
collect any engine oil or coolant that drains from
the oil cooler.
2. Refer to Disassembly and Assembly , "Engine
Oil Cooler - Remove" for removal of the engine
oil cooler.
3. 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 pro-
tective face shield and protective clothing.
Maximum air pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.
4. 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.
5. Refer to Disassembly and Assembly , "Engine
Oil Cooler - Install" for installation of the engine
oil cooler.
6. Ensure that the cooling system of the engine is
filled to the correct level. Operate the engine.
Note: Refer to the Operation And Maintenance
Manual, "Refill Capacities" for additional information.
Check for oil or coolant leakage.

Personal injury can result from escaping fluid un-
der pressure.
If a pressure indication is shown on the indicator,
push the release valve in order to relieve pressure
before removing any hose from the radiator.
1. Remove the water temperature regulator from
the engine. Refer to Disassembly and Assembly
Manual, "Water Temperature Regulator - Remove
and Install".
2. Heat water in a pan until the temperature of
the water is equal to the fully open temperature
of the water temperature regulator. Refer to
Specifications, "Water Temperature Regulator"
for the fully open temperature of the water
temperature regulator. Stir the water in the pan.
This will distribute the temperature throughout the
pan.
3. Hang the water temperature regulator in the pan
of water. The water temperature regulator must
be below the surface of the water. The water
temperature regulator must be away from the
sides and the bottom of the pan.
4. Keep the water at the correct temperature for ten
minutes.
