BRAKE SYSTEM
PRECAUTION
Care must be taken to replace each part properly as it could affect the performance of the brake
system and result in a driving hazard. Replace the ones with parts having the same part number
or equivalent.
It is very important to keep the parts and the area clean when repairing the brake system.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
INTRODUCTION.

INSPECTION
1. INSPECT THERMOSTAT
HINT:
The thermostat is numbered with the valve opening tempera-
ture.
(a) Immerse the thermostat in water and gradually heat the
water.
(b) Check the valve opening temperature of the thermostat.
Valve opening temperature:
80 to 84C (176 to 183F)
If the valve opening temperature is not as specified, replace the
thermostat.
(c) Check the valve lift.
Valve lift: 10 mm (0.394 in.) or more at 95C (203F)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve is fully closed when the thermostat
is at low temperatures (below 77C (171F)).
If not closed, replace the thermostat.
2. INSPECT RADIATOR CAP SUB±ASSY
NOTICE:
If the radiator cap is contaminatied, rinse it with water.
Before using a radiator cap tester, wet the relief valve
and the pressure valve with engine coolant or water.
When performing following steps (a) and (b), keep the
tester at an angle of over 30 above horizontal.
