Note
The impeller is made from reinforced plastic. The impeller is at
an increased risk of breakage during installation work on the
water pump due to the hardness of the material.

- Map-controlled thermostat

The map-controlled thermostat allows the engine to be cooled
in accordance with the relevant operating conditions. This
reduces fuel consumption by around 1-6%.
The electrical connections, the design and the map-controlled
thermostat throttle response have been optimized.
The map-controlled thermostat function is the same as that for
previous engines (M62).
