BMW Serie 3 - Video tutorial

Model: BMW Serie 3 E46 - Years 1998-2006
Part: Alternator
Operation: Alternator belt replacement on BMW 3

Disassembly of the non-working alternator? We see the disassembly and replacement inside the engine compartment of the BMW 3. We open and lift the bonnet, remove the engine panel, remove the air duct pipe and if necessary the front bumper. With a fixed wrench we go to loosen the belt tensioner roller and remove the belt from its seat. With a socket wrench we go to unscrew the tightening pin of the belt tensioner roller and unscrew the alternator tightening screws. We remove the alternator from inside the engine compartment. We mount the new alternator, the belt tensioner and the belt itself, we tighten everything with the socket wrench. We test the functioning at the end of the assembly of all the pieces.

Handbrake adjustment on Ford Ecosport

First remove the plastic profile at the base of the gear lever. To do this, slightly widen the side edges and carefully lift it to release it. There is no need to remove it completely, just move it forward to avoid bother. Now remove the plastic center console around the handbrake by first working from the rear to release it and lifting it until the brake lever passes. Also in this case it is not necessary to remove it completely but, paying attention to the connected cables, it can be stowed in front of the passenger seat. At this point we notice that at the base of the handbrake lever, on the front, we find a nut. By acting on it, with a 10 wrench, we can adjust the brake force, increasing it by turning the nut clockwise, or decreasing it by turning it counterclockwise. Once adjusted, the center console can be repositioned first, pressing lightly to engage it, and then the profile of the gearbox base.
