Installing the Heater Control Valve Assembly
The installation is the reverse of the removal
procedure.
NOTE Fill the cooling system with the
recommended coolant. Check for coolant
leaks from radiator and hoses.
Heater core
The heater is a kind of heat exchanger.
When the high-temperature coolant flows
through the heater, it exchanges heat with
the cold air in the car, never achieving the
purpose of heating in the car and
defrosting the windows.
AIR SUPPLY SYSTEM
The air in the car is forced into the HVAC
assembly by the blower, and then sent to
the cabin after passing through the filter
screen and ventilation pipe to realize the
heating or cooling in the cabin.

NOTE If you need to turn on the warm air
when you park for a long time and find that
there is no hot air through the outlet,
please increase the idle speed while
ensuring the normal operation of the
blower, there will be a steady stream of hot
air for you.
Removing the Outlet Louver
The air outlet is inlaid on the air outlet
elbow and can be removed by gently prying
with a flat head screwdriver.
