− COOLINGCOOLANT
1996 RAV4 (RM447U)
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 radiator drain plug (on the left side of the ra-
diator lower tank) and engine drain plug (on the left rear
of the cylinder block), and drain the coolant.
(c) Close the drain plugs.
Torque: Engine drain plug
25 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 manufacture’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):
M/T: 8.0 liters (8.5 US qts, 7.0 lmp. qts)
A/T: 7.7 liters (8.1 US qts, 6.8 lmp. qts)
(b) Install radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) Refill the radiator reservoir with coolant until it reaches the
”FULL” line.
