Disassembly Procedure

2006 Chevrolet Suburban C1500, 5.3 ZSECTION Disassembly Procedure
WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The ignition system distributor driven gear and rotor may be installed in multiple positions. In order to avoid mistakes, mark the distributor on the following components in order to ensure the same mounting position upon reassembly:
  • The distributor driven gear
  • The distributor shaft
  • The rotor holes

Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine wear or damage may result.
  1. Remove the distributor. Refer to Distributor Replacement .
  2. Align the white paint mark on the bottom stem of the distributor, with the pre-drilled indent hole in the bottom of the gear (2).
  3. With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1). If not, replace the distributor.
