REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the 2 drain plugs (for the engine and radiator),
and drain the coolant.
HINT:
To prevent the coolant from spraying over the cylinder block,
connect the rubber hose (inside diameter 6 - 8 mm) in the mar-
ket to the union pipe under.
(c) Close the drain plugs.
Torque:
Engine drain plug
29 N´m (300 kgf´cm, 22 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 wa-
ter or distilled water.
Capacity (w/ Heater):
