Some more advice please! My radiator fans cut out when engine turned off. Us that correct? I am sure on other cars I have had the fans run on for a while after shutdown?

Mine does this too - usually I wait until the (high speed?) fan has stopped before turning the engine off while it's doing its stuff.

The fans on the 24v ( and some other models ) are controlled by the engine ecu. They won't operate with the engine off. Even those where the engine ecu doesn't control the fan(s), the fan relays will be energised by an ignition supply.

So, in summary, the fans will not operate after shutdown.

Probably not needed on an alloy engine anyway as they don't suffer from the 'heat sink' effect after they stop running.

Always doubted the value of the fan running after switch off as the water pump is no longer pumping the coolant
through the radiator anyway, and the cooling effect of the fan on the engine would be negligible.
