Inspecting the left side oil cooler
Test the oil path with compressed air of 1.47 MPa (15
kgf/cm 2 ) [213 psi] for damage or cracks in the ele-
ment. If there is any leakage, replace the element.
Inspection the left side thermostat
1. Inspect the oil thermostat seal for deterioration
and cracks. If any are found, replace the seal.
2. Refer to the drawing on the right that shows the
correct direction for seal installation.
3. Operation testing
Immerse the thermostat in engine oil, then measure
the temperature where the valve opens, then mea-
sure it again when the valve lift is 11 mm [0.43 in.].
Replace the thermostat if temperatures are not within
standard.
Temperature for valve opening, °C [°F]
Assembly Standard ... 80–84 [176–183.2]
Temp. for 11 mm [0.43 in.] valve lift, °C [°F]
Assembly Standard ... 95 [203]
IMPORTANT! Stir the oil to maintain even tem-
peratures during the test.
IMPORTANT! At reassembly, confirm the valve
opening temperature stamped on its mounting
flange.

Reassembly

Reassembly is the reverse procedure of disassembly.
1. Replace packing and O-rings for reassembly.
2. Before reassembly, clean the oil paths of the oil
filter bracket, etc. by flushing them with oil and
blowing them with air.
3. Install the oil filter element with its bracket.
