Pelican Parts https://www.pelicanparts.com > BMW > techarticles
Need to retime your cams? VANOS unit need replacing? Here's the details on timing your engine, and the install of this tricky unit.
..

Hi there , there should be a adjuster on the alternator, unless it's a serpentine belt, if a serpentine belt then you will need a new tension bled idler, hope this helps.

General advice:
Oil/filter replace.
Air filter replace.
Fuel filter replace.
Brakes/pads/oil/discs/dust proof sealers,
Timing /tension.
Valves adjust.
Wheels alignement/balance .
Tires condition/pressure.
Engine compartiment belts.
Battery/alternator condition/charge rate.
Lights alignement/hight ceck.
Thermostat open/thermoswitch triggers fan.
Coolant ceck/change.
AC pressure.
Doors/trunk/hood/roof look/hinges oiling.
Remote battery ceck.
Pretty much everything if u care 4ur car.
Cheers.
