2003 1.8 Installation position of Excelle heating water pipes

The warm air water tank is located in the engine compartment, and the warm air water valve is located on the water inlet pipe of the warm air water tank. You can find it along the cooling system pipeline after opening the engine compartment.

The heater box is only a heating component in the hot air conditioning system. When the water in the engine passes through the heater box, the heater box is heated, and the fan works to blow air against the heater box. When the wind passes through the warm air trough, it is warm air coming out of the air outlet.
