Venting cooling system and checking for
leaks (M47/M57)

Warning!

Danger of scalding!

Only perform this work after engine has cooled down.

Caution!

When working on the oil, coolant or fuel circuit, you must
protect the alternator against contamination.

Cover alternator with suitable materials.

Failure to comply with this procedure may result in an
alternator malfunction.

Drain off and top up coolant,

refer to 17 00 005.

Check cooling system for leaks,

refer to 17 00 009.

Note:

To ensure that the cooling system is properly vented, it is
absolutely essential to adhere to the following steps:

1)

Open expansion tank.

2)

Start engine (idle speed) and set heater to maximum
temperature. Set blower to low setting. This opens the
heating valves and sets the auxiliary water pump in
operation.
