2.3 Removing and installing auxiliary heating
Note: If the auxiliary heating is replaced, first connect the diagnostic unit - Vehicle diagnostic tester and the function “replace control unit” is called up under the guided functions of the relevant control unit.
Install all cable ties and other fasteners for the electrical cables at the same places from which they were detached/cut when they were removed.
Special tools and workshop equipment required
Hose clamps - MP7-602 (3094)-
Removing
– With the ignition switched off, disconnect battery earth strap
– Remove the front bumper
WARNING:
The cooling system is under pressure, the coolant temperature can be over 100 °C when the engine is warm - risk of burning!
Before repairs, reduce pressure and temperature if necessary. Parts of the exhaust system can be hot.
Let the exhaust system cool down before the removal.
– Remove exhaust system of auxiliary heating
– Place the catch pan under the auxiliary heating.
– Disconnect the coolant hoses from the hose clamps - MP7-602 (3094)- .
– Slacken the clamps -1- and detach the coolant hoses from the pipes.
Note: Observe safety measures when working on the fuel system
WARNING: There is a risk of fuel escaping. The fuel system is under pressure!
Lay a clean cloth on the connection point and carefully disconnect the connection point in order to relieve the pressure in the fuel system.
– Disconnect the quick coupling of the fuel line from the heater.
– Close the fuel line -3- with a suitable screw plug after detaching it.
– Remove the retaining clips and the wiring harness from the heating system fixing screws.
– Release the nuts -2- and remove the auxiliary heating from the frame side rail.
Caution: Stress can occur on the plugs and the auxiliary heating control unit - J364- can get damaged.
First of all unplug the 6-pin connector.
– Carefully tilt the auxiliary heating towards the rear, first unplug and remove the connector -1- (6-pin) and then the connector -2-.
– Remove auxiliary heating.
Installing
Installation is performed in the reverse order, pay attention to the following points:
Caution: When undertaking all installation work, particularly in the engine compartment due to its cramped construction, please observe the following:
Lay lines of all kinds (for fuel, cooling fluid and refrigerant, electrical lines) in such a way that the original line guide is re-established.
Ensure that there is adequate free access to all moving or hot components.
– Install auxiliary heating and connect the hoses which are secured with the hose clamps -1- and -2-. Do »NOT« open the clamps yet.
– Slacken the hose clamp -3-, detach the hose -4- and hold it vertically upwards.
– Only loosen the hose clamp -2- when coolant begins to flow out.
– Close hose clamp -2- again.
– Only when coolant begins to flow out the hose -4-, loosen the hose clamp -1-.
– Close hose clamp -1- again.
– Reinstall the hose -4- and remove the hose clamps -1- and -2-.
– Ventilate the refrigerant circuit of the auxiliary heating
– Interrogate event memory and if necessary erase entries - Vehicle diagnostic tester.
Note:
If more air enters the coolant system during the installation, the complete refrigerant circuit must be ventilated
Cooling system/coolant; Draining and filling coolant .
Pay attention to the sequence when connecting the battery earth strap
If the auxiliary heating is replaced by a new one, it must run at full load mode for at least 10 minutes before handing it over to the customer. There can still be lubricant residues in or on the components of the auxiliary heating fitted at the factory, which evaporate after it is switched on for the first time. The smoke which occurs may worry the customer and he might look upon the auxiliary heating as defective.
