Coil Rail: Installation

  1. Connect engine harness connector to coil by snapping into position. Move slide tab towards engine (Figure ) for a positive lock.
  2. Position ignition coil rubber boots to all spark plugs. Push down on coil assembly until bolt bases have contacted cylinder head
  3. Install 4 coil mounting bolts. Loosely tighten 4 bolts just enough to allow bolt bases to contact cylinder head. Do a final tightening of each bolt in steps down to 29 N.m (250 in. lbs.) torque. Do not apply full torque to any bolt first.
  4. Connect negative battery cable to battery.
