Hi do you need to take the engine out to change the tensioning pulley
Re the alternator
Doesn't appear to be any access
Took off the cover behind the wheel and can see the bottom accessory pulley but the other is right up inside
Any help please

Everything is tough to access. If one need into the timing belt. Now, we're going to need some time; and beers! :help:

While mainly the alernator and sometimes the top engine mount need to be removed to get your hands down to the fan belt.

I hope someone can help me here... I have a freelander TD4.... with BMW M47 motor in which the serpentine belt tensioner is seizing....I want to remove the pulley, but having a problem as to how to... Does the large 24mm bolt hold the pulley in place and must I loosen that to get the pulley off the arm to replace the bearing??
