Bmw 2002 740il remove alternator
As for loosening the alternator belt, you're supposed to only loosen the two hex bolts above the roller, that loosens the belt enough to take it off – there's not need to remove the roller itself, unless it makes noises.
For tightening, use a wrench on the hex section behind the lower screw to push the assembly counter-clockwise until the upper screw is all the way at its end, then tighten both screws (30 Nm for the water cooled variant).
E38 740d thermostat keeps themp lower… about 88c
After seeing this, I am glad I bought a 2001 BMW 530i and not the 2001 540i. The extra power in the 540i doesn't out way the headache and extra expense !
What year 540 is this? I have a 98 (04/98 production year) 540i with air cooled alternator.
This is key remember guys when u do this job disconnect the battery this is crucial. Also since u have it broke down this is a good time to change ur belts cheers.
why is it that the M62's run so much hotter than S62? engineering wise
that guy has bad fan clutch…u can see fan spining backwards very easly and not giving any resistance….
Hey thanks for this, this is the exact thing I need to do. So far I've gotten the alternator out.
Fuck getting a E39! A water cooled alternator, what the hell? That is just over complicated and poor engineering.
Glad my e46 has a NORMAL alternator.
Jeez
