ENGINE COOLING ± On-vehicle Service
14-10
CONCENTRATION MEASUREMENT
Measure the temperature and specific gravity of the engine
coolant to check the antifreeze concentration.
Standard value: 30± 60% (allowable concentration range)
RECOMMENDED ANTIFREEZE
Antifreeze Allowable concentration
MITSUBISHI GENUINE COOLANT
or equivalent
30± 60%
Caution
If the concentration of the antifreeze is below 30 %, the
anti-corrosion property will be adversely affected. In
addition, if the concentration is above 60 %, both the
anti-freezing and engine cooling properties will decrease,
affecting the engine adversely. For these reasons, be sure
to maintain the concentration level within the specified
range.
FAN CONTROLLER CHECK
1. Disconnect the condenser fan motor connector.
2. Start the engine and run it at idle.
3. Turn the A/C switch to ON and maintain the coolant
temperature at 80_C or less.
4. When measuring the voltage between the fan
controller-side connector terminals, check that the value
changes repeatedly as indicated by (1) ± (3) below.
(1) 0 V
(2) 8.2 ± 2.6 V
(3) Battery voltage ± 2.6 V
5. If the voltage does not repeatedly change as indicated,
replace the radiator fan motor and the fan controller
assembly.
