5) Install alternator V-belt:
After adjusting V-belt tension, tighten alternator
bracket lock bolt securely.
G4M0632
6) Check drive belt tension and adjust it if neces-
sary by changing alternator position and/or idler
pulley position.
CAUTION:
IEnsure that the V-belt is aligned correctly. If
it is not, check for loose bolts.
IThe V-belt should not be too tight or too
loose.
A belt which is too tight may break bearing or
cause gas to leak from the shaft seal. A belt
which is too loose slips, thereby causing the
belt cut.
IAfter completing the compressor installation
and testing the system operation, check and
adjust the tension of both V-belts again.
