COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR TANK
The coolant level should be between the ”LOW” and ”FULL” lines.
If low, check for leaks and add 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 radiator 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
1. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove it while
the engine and radiator are still hot, as fluid and steam can
be blown out under pressure.
(b) Drain the coolant from the radiator drain plug and engine
drain plug. (Engine drain plug at the right of engine block.)
(c) Close the drain cock plug.
Torque:Torque (Engine drain plug):
24 N·m (250 kgf·cm, 18 ft·lbf)
2. FILL ENGINE COOLANT
(a) 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/ Heater):
8.7 liters (9.2 US qts, 7.7 lmp. qts)
(b) Reinstall the radiator cap.
(c) Warm up the engine and check for leaks.
(d) Recheck the coolant level and refill as necessary.
