Another E39 question

well you've kind of replaced everything but the fan clutch, which means It could be your main fan isn't cooling enough

how do you check the fan clutch?

I am pretty sure it should tell you also, on this site if you search. I think that the e39 clutch will be similar in operation to the e34 (bimetallic strip based)

I'd suspect the fan clutch to be bad. You shouldn't need the aux fan if that's working properly, and the fact that it's coming on late means your primary cooling fan isn't functioning like it should be.
