HEATER SYSTEM [(E)]

id0711000025x2

Outline

• The heater system warms the heater core using the engine coolant warmed by the engine operation.

• To improve the heating performance temporarily under cold diesel engine conditions, a PTC heater which uses electricity as the heat source as been adopted. (SKYACTIV-D 1.8 (With PTC heater))

Function

Heater core

• The heater system intakes a portion of the warmed engine coolant into the heater core and circulates it.

• The heater core consists of a tube which passes engine coolant, and the heat radiation fin.

PTC heater (SKYACTIV-D 1.8 (With PTC heater))

• The heater system warms the air passing in the A/C unit using the heat generated by the PTC heater.

Operation

1. Engine coolant flows into the heater core by the operation of the water pump.

2. When the warmed engine coolant circulates in the heater core, the heater core warms up.
