•
The dial indicator remains constant beyond five
minutes.
The inside of the cooling system has leakage only
if the following conditions exist:
•
The reading on the gauge goes down.
•
You do NOT observe any outside leakage.
Make any repairs, as required.

Engine Oil Cooler - Inspect

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
Perform the following procedure in order to inspect
the engine oil cooler (if equipped):
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 flange face of the cover
plate 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 cooling plates for cracks and dents.
Replace the cooling plates if cracks or dents exist.
If necessary, clean the outside and clean the inside
of the cooling plates. Use a solvent that is not
corrosive on copper. Ensure that no restrictions for
the flow of lubricating oil exist in the cooling plates.
Dry the cooling plate with low pressure air.
Flush the inside of the cooling plate 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 and the oil system
of the engine are filled to the correct level. Operate
the engine. Check for oil or coolant leakage.
Water Temperature Regulator
- Test
i02265391
Note: Do not remove the water temperature regulator
from the water temperature regulator housing in
order to perform the test.
1. Remove the water temperature regulator housing
which contains the water temperature regulator
from the engine. Refer to Disassembly and
Assembly, "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 housing in
the pan of water. The water temperature regulator
housing must be below the surface of the water.
The water temperature regulator housing must be
away from the sides and the bottom of the pan.
4. Keep the water at the correct temperature for ten
minutes.
5. After ten minutes, remove the water temperature
regulator housing. Immediately measure the
opening of the water temperature regulator.
Refer to Specifications, "Water Temperature
Regulator" for the minimum opening distance of
the water temperature regulator at the fully open
temperature.
If the distance is less than the amount listed in the
manual, replace the water temperature regulator.
Refer to Disassembly and Assembly, "Water
Temperature Regulator - Remove and Install".
Install the water temperature regulator. Refer to
Disassembly and Assembly, "Water Temperature
Regulator - Remove and Install".
