4.  DISCONNECT WATER BYPASS HOSES FROM OIL
COOLER
5.  REMOVE OIL COOLER
(a)  Remove the relief valve, plate washer and oil cooler.
(b)  Remove the 2 O±rings from the oil cooler.
OIL COOLER INSPECTION
1.  INSPECT RELIEF VALVE
Push the valve with a wooden stick to check if it is stuck.
If stuck, replace the relief valve.
2.  INSPECT OIL COOLER
Check the oil cooler for damage or clogging.
If necessary, replace the oil cooler.

COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant up to the
ºFULLº line.
2.  CHECK ENGINE COOLANT QUALITY
(a)  Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not remove
the radiator cap while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b)  There should not be any excessive deposits of rust or scale
around  the radiator cap or radiator filler hole, and the coolant
should be free from oil.
If excessively dirty, replace the coolant.
(c)  Reinstall the radiator cap. EG±330
