The OM617 Accesory Belt Tensioner is designed to be used with the Doomsday OM617 A/C and New 22R/3VZE Power Steering Brackets on the furthest rearward pulley. The A/C compressor and power steering pumps remain stationary. This bracket is bolted on in place of the OM617 A/C compressor. The tensioner pulley is lined up with the furthest rear crankshaft pulley. The 22R idler-tensioner pulley is used. If you need a new pulley, a working part number is ACDelco 36725. The bracket and pulley are shown installed in the bottom right corner of the 3rd picture.
THE PULLEY IS NOT INCLUDED WITH THIS KIT! This kit includes the steel bracket and hardware.
