Scheme 5

Scheme 5: Removing bracket for oil-water heat exchanger

Note. The following step must only be performed for the M48/50 engine.

1. Undo both oil return lines from the turbochargers to the oil filter bracket. Pull the connections slightly out of the bracket.

2. Release coolant lines from oil-water heat exchanger. To do this, release the two spring-band clamps and pull the lines upwards.

3. Unscrew the 3 fastening screws on the bracket.

CAUTIONDanger of injury! When pulling the bracket off, even greater amounts of engine oil can leak out. If the bracket is stuck, it can loosen abruptly. If this happens, your fingers could be injured.

> Proceed carefully when pulling out the bracket.

> Collect escaping fluids.

4. Pull off the bracket from the engine in a forward direction. If the bracket is stuck very firmly, lever it off very carefully using a suitable implement.
