Timing Drive Components: Installation

WARNING: This page is about a different car, the 2011 Ford Pickup and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Timing chain procedures must be followed exactly or damage to valves and pistons will result.
  1. Using a small pick, carefully push the tensioner rack pawl retainer away from the rack pawl and compress the tensioner plunger and rack using a vise.
