Installation Note

Timing belt auto tensioner

  1. 1
    Slowly press the tensioner rod into the tensioner body by using a press.
    Applying pressure of more than 9,807 N {1,000 kgf, 2,200 lbf} can damage the tensioner.
    Illustration of the auto tensioner being compressed in a press; a 'ALIGN THE HOLES' label points to the alignment of the tensioner mounting holes.
  2. 2
    Insert a pin into the second hole in the body as shown to hold the tensioner rod.
    Pin diameter: 1.6mm {0.063 in}
    Illustration of the auto tensioner with a 'PIN' label pointing to a pin inserted into the second hole in the tensioner body to hold the rod.
  3. 3
    Set the tensioner in place and snugly tighten the tensioner upper bolt.
    This must be done to reduce the timing belt resistance when the idler pulley is installed.
    Illustration of the tensioner set in place among the pulleys and timing belt; an arrow points to the tensioner upper bolt to be snugly tightened.

  1. 1
    Turn the camshaft pulleys clockwise and align the timing marks.
