ENGINE COOLING -General Information/
Service Specifications/Lubricant/Sealant14-2
GENERAL INFORMATION
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.

Caution
1) Before operating the pre-tensioner, see that
no one is in and near the vehicle.
2) The operation of the pre-tensioner makes the
inflator very hot. Before handling the inflator,

DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1) This should be carried out in a wide, flat area at least
6 m away from obstacles and other people.
2) Do not operate outside if wind is high. Even in a soft
wind, ignite to windward of the pre-tensioner.
1. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work. (Refer
