Removal & Installation: Installation

1. Place timing belt tensioner in a press, using a flat washer to prevent damage to timing belt tensioner plug.
2. Compress automatic belt tensioner until hole in piston aligns with second hole in housing. Insert a .06" (1.5 mm) diameter pin, or drill through hole to keep piston in compressed position. See Figure.
3. Ensure camshafts and crankshaft timing marks align. See Fig 1. Turn crankshaft counterclockwise until crankshaft timing sprocket is offset from TDC by one tooth. See Fig 2. Install timing belt.
4. Turn crankshaft clockwise until crankshaft timing mark is back to TDC. This should put slack on tensioner portion of belt. Install automatic timing belt tensioner, and tighten bolts to specification. See TORQUE SPECIFICATIONS . Remove pin from automatic tensioner.
5. Turn crankshaft 2 complete revolutions. Recheck timing marks to ensure timing is still correct. See Fig 1. To complete installation, reverse removal procedure. Tighten bolts to specification. Check ignition timing. Adjust drive belts to proper tension.
