CHECKING THE THERMOSTAT ASSEMBLY

1. Check:

• Thermostat “1”

Does not open at 74–78°C (165–172°F)

→

Replace.

a. Suspend the thermostat “1” in a container

“2” filled with water.

b. Slowly heat the water.
c. Place a thermometer “3” in the water.
d. While stirring the water “4”, observe the

thermostat and thermometer’s indicated
temperature.

e. Check the thermostat element position

“5”.
Same level for the thermostat element up-
per end and the hole lower line “a” at 90 °C
(194 °F)

TIP

If the accuracy of the thermostat is in doubt, re-
place it. A faulty thermostat could cause serious
overheating or overcooling.

INSTALLING THE THERMOSTAT
ASSEMBLY

1. Fill:

• Cooling system

(with the specified amount of the recom-
mended coolant)

• Coolant air bleed from engine

Refer to “CHANGING THE COOLANT” on
page 3-16.

2. Check:

• Cooling system

Leaks

→

Repair or replace any faulty part.

Refer to “INSTALLING THE RADIATOR” on
page 6-3.

3. Measure:

• Radiator cap opening pressure

Below the specified pressure

→

Replace the

radiator cap.
Refer to “CHECKING THE RADIATOR” on
page 6-3.
