Just got my 8l back on the road, after a sudden coolant loss due to overheating, which also cracked the head, and the hotside on the k04.
When diagnosing it I tested and replaced the cooling fan.
Questions I have are:
Currently the cooling fan only runs if the engine is running. It appears to be switched correctly at 97 and 102 degrees, but if I turn the engine off, the fan stops. The turbo coolant pump does run though, with the engine off.
Is it correct that the cooling fan doesn't run after turning the engine off?
Is there a way of forcing the cooling fan to run, by pulling a fuse or anything?
I have a spare fan control relay box, but I'm unsure of how it is supposed to work.
Any knowledge or link would be Much appreciated. It appears the cooling system electrical side is little talked about online.
Thanks!
