   1. Clamp it in a vise equipped with soft jaws, in a level position. Use a plain washer if there is a plug at the bottom of the auto tensioner.
   2. Compress the rod slowly with the vise until the set hole in the rod is aligned with set hole in the cylinder.

   3. Insert a set pin through the auto tensioner body and rod.
      CAUTION: Leave the set pin installed in the auto tensioner.
6. Align the timing marks of each sprocket and install the timing belt in this order.

   Crankshaft sprocket --> Idler pulley --> Exhaust camshaft sprocket (LH) --> Intake camshaft sprocket (RH) --> Exhaust camshaft sprocket (RH) --> Tensioner pulley.

   NOTE:

   • In this step, No. 1 is in TDC (Compression stroke)
   • Do not insert fingers.
7. After installing the timing belt, reconfirm the timing mark.
8. Pull out the set pin of auto tensioner.
   NOTE:

   1. Rotate the crankshaft 2 rotation clockwise and measure the projected load of auto tensioner in the TDC (# 1 compression stroke) after 5 minutes.
   2. Check the projected length is 3.8 ~ 4.5 mm.
   3. Check again if the timing marks of each sprocket is with in specified position.
9. Install the engine support bracket.
10. Install the timing belt cover.
11. Install the alternator and drive belt.
12. Install the engine mounting bracket.
13. Install the side cover.
14. Install the wheel of passenger side.
