NOTE:
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacturer's instructions at all times.
3. Be absolutely sure to remove all lubricants and moisture from the connecting surfaces before applying
the liquid gasket.
The connecting surfaces
must be perfectly dry.
4. Do not apply LOCTITE 17430, LOCTITE 515 and LOCTITE 518 between two metal surfaces having a
clearance
of greater than 0.25 mm (0.01 in). Poor adhesion will result.

1A-2 HEATING AND VENTILATION
GENERAL DESCRIPTION
HEATER
When the engine warming up, the warmed engine
coolant is sent out into the heater core. The heater
system
supplies warm air into the passenger
compartment to warm it up.
Outside air is
circulated through the heater core of
the heater unit and then back into the passenger
compartment. By
controlling the mixture of outside
air and heater core air, the
most comfortable
passenger compartment temperature can be
selected and maintained.
The temperature
of warm air sent to the passenger
compartment is controlled by the temperature
control knob. This knob acts to open and close the
air
mix door, thus controlling the amount of air
passed through the heater core.
Defroster nozzle
Side
def hose
The air selector knob, with its different modes, also
allows
you to select and maintain the most
comfortable passenger compartment temperature.
The air source
select lever is used to select either
"FRESH" for the introduction of the outside air, or
"CIRC" for the circulation of the inside air. When the
lever is set to "FRESH", the outside air is always
taken into the passenger compartment. When
setting the
lever to "CIRC" position, the circulation
of air is restricted only to the inside air with no
introduction
of the outside air and the air in the
passenger
compartment gets warm quickened.
However, the
lever is normally set to "FRESH" to
prevent the windshield from clouding.
