COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ”LOW” and ”FULL”\
lines.
If low, check for leaks and add engine coolant up to the ”FULL” line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the r\
adiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

REPLACEMENT
REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
See step 2. (a) above.
(b) Drain the coolant from the radiator drain cock and engine drain plug (Engine drain plug at the left of engine block.).
(c) Close the drain plugs. Torque:Torque (Engine drain plug):
29 N·m (300 kgf·cm, 22 ft·lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene −glycol base coolant
and mix it according to the manufacturer’s direc-
tions.
Using coolant which includes more than 50 % ethyl-
ene−glycol (but not more than 70 %) is recom-
mended.
NOTICE:
Do not use an alcohol type coolant.The coolant should be
mixed with demineralized water or distilled water. Capacity:
w/ Front heater:
13.7 liters (14.4 US qts, 12.1 lmp. qts)
w/ Front and rear heaters:
14.7 liters (15.5 US qts, 12.9 lmp. qts)
(e) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
