Some models are equipped with an electric heating element, which additionally heats the air. The element is switched on by the engine control unit depending on the ambient air and coolant temperature and the generator load when the handle on the heater control panel is set to maximum heating.
1. Disconnect the wire from the "-" terminal of the battery.
2. Remove the floor console.
3. Drain the engine cooling system or pinch off the outlet 1 (see the figure Connecting hoses to the heater radiator) and 2 supply hoses of the heater radiator (if the heater radiator is removed for replacement, the fluid must be drained).
4. From the engine compartment side, mark the position of heater pipe 4 and unscrew bolt 5 that secures it. Remove the branch pipe and set it aside along with the hoses.
