Thermostat InspectionS7RS0B1606008
• Make sure that air bleed valve (1) of thermostat is clean.
• Check to make sure that va lve seat (2) is free from 
foreign matters which would prevent valve from 
seating tight.
• Check thermostat seal (3) for breakage, deterioration  or any other damage.
• Check thermostatic movement of wax pellet as  follows:
a. Immerse thermostat (1) in water, and heat water  gradually.
b. Check that valve starts to open at specific  temperature.
Temperature at which valve begins to open
80 – 84  °C (176 – 183  °F)
Temperature at which valve become fully open
95 – 97  °C (203  °F)
Va l v e  l i ft
More than 8 mm at 95  °C (203 ° F)
If valve starts to open at a temperature substantially 
below or above specific temperature, thermostat unit 
should be replaced with a new one. Such a unit, if 
reused, will bring about ov ercooling or overheating 
tendency.

Lower than recommended pressure can cause:
• Tire squeal on turns
• Hard Steering
• Rapid and uneven wear on the edges of the tread
• Tire rim bruises and rupture
• Tire cord breakage
• High tire temperature
• Reduced handling
• High fuel consumption
Replacement Tires
When replacement is necessary, the original equipment 
type tire should be used. Refer to the Tire Placard. 
Replacement tires should be of the same size, load 
range and construction as those originally on the vehicle. 
Use of any other size or type tire may affect ride, 
handling, speedometer / odometer calibration, vehicle 
ground clearance and tire or snow chain clearance to the 
body and chassis.
It is recommended that new tires be installed in pairs on 
the same axle. If necessary to replace only one tire, it 
should be paired with the tire  having the most tread, to 
equalize braking traction.
WARNING! 
Do not mix different types of tires on the 
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because 
handling may be seriously affected and may 
result in loss of control.
 
The metric term for tire infl ation pressure is the kilo 
pascal (kPa). Tire pressures is usually printed in both 
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used 
inflation pressures  from kPa to kgf/cm
2 and psi.
Wheels DescriptionS7RS0B2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are 
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have 
excessive lateral or radial runout, air leak through welds, 
have elongated bolt holes, if  lug wheel bolts won’t stay 
tight, or if they are heavily rusted. Wheels with greater 
runout than shown in the following may cause 
objectional vibrations.
Replacement wheels must be equivalent to the original 
equipment wheels in load capacity, diameter, rim with 
offset and mounting configuration. A wheel of improper 
size or type may affect wheel and bearing life, brake 
cooling, speedometer / odometer calibration, vehicle 
ground clearance and tire clearance to body and 
chassis.
How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an 
accurate dial indicator. The tire may be on or off the 
wheel. The wheel should be  installed to the wheel 
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial 
runout “b” at both inside an d outside of the rim flange. 
With the dial indicator set  in place securely, turn the 
wheel one full revolution slowly and record every reading 
of the indicator.
When the measured runout  exceeds the specification 
and correction by the balancer adjustment is impossible, 
replace the wheel. If the reading is affected by welding, 
paint or scratch, it should be ignored.
Lateral runout limit “a”
: 0.3 mm (0.012 in.)
Radial runout limit “b”
: 0.3 mm (0.012 in.)
