Part Number: W0133-1628529
Notes: Auxiliary - New-style drive belt designed for greater contact with alternator pulley. Can be used on models that used old-style belt routing (850 models, 93 & later up to eng#554663; 92-94 960 models) if belt is installed to place center idler pulley between p/steering pump and alternator (new routing) rather than alternator and air cond compressor (old routing). 850 models later than those above already have the new-style belt & use the new routing. Install belt as noted & tension as usual. No other changes needed!

Part Number: W0133-1660732
Notes: Auxiliary Volvo has superseded earlier belt #9434341 (6PK-1748) to this number due to stretching problems over time.

Part Number: W0133-1630621
Notes: Auxiliary- Old Style - Can use belt #9434341 (6PK-1748) for greater contact with alternator pulley. Though no other mechanical modifications are required to install this upgrade, belt routing will need to be changed to use the longer belt. See note attached to #9434341 for more information.
