Hi , any one know at what temp the cooling fan should kick in on the M47 td4 , stat opens at 88ish but cant find the fan operation temp , thanks

see pic :


if pic can't be viewed .. it's :

fan speed 1 .. coolant temp. on 100c .. aprox. temp. off 95c
fan speed 2 .. coolant temp. on 106c .. aprox. temp. off 102c
fan speed 3 .. coolant temp. on 112c .. aprox. temp. off 106c

.. On vehicles fitted with air conditioning the EDC ECM will grant air conditioning, dependant on
coolant temperature, and fan speed 1 when air conditioning is requested via the CAN-Bus
from the instrument pack. The fastest fan speed from either system always assumes priority
( above from the M47r diesel pdf doc. )
