Re: BMW 328i Starter how to replaice
1999 BMW 328I 2.8L EFI DOHC 6cyl
Starter - Removal & Installation
The
starter motor on some models is very difficult to see from the top of
engine compartment as it is covered by the intake manifold. On these
models, without removing the intake manifold, the starter motor must be
removed from underneath the vehicle. Because the starter motor mounting
bolts are not easy to access, a long extension with a universal joint
mounted on a proper sized socket could be used. A three foot
transmission extension is commercially available from tool vendors that
has a 3
/
8
inch drive of the driven end and
1
/
2
inch drive on the drive end. If used with a non-binding impact
universal joint and a proper fitting impact socket, the starter motor
fasteners can be removed from underneath the vehicle.
Once the starter motor fasteners are removed, the
starter motor may have to be moved side-to-side several times to loosen
the dowel pin if it has corroded in place.
NOTE
When the battery is disconnected, the radio code, on-board
computer and clock settings will be lost. The radio code should be
obtained before disconnecting the battery or radio. Once the battery
has been reconnected, the radio will not function unless the code is
keyed in.
