Hey guys,
When I replaced the water pump on my mighty Metro a while back, I neglected to mention that I also replaced the timing belt since accessibility was a breeze. These two maintenance jobs go hand in hand so if your performing one job, it behoves you to perform the other at the same time ;)
Without further ado, here is the procedure for replacing the timing belt on a '00 Metro equipped with the four banger:
1) Remove the timing belt cover.
2) Align the upper and lower timing marks.
3) Loosen the timing belt tensioner. Push the tensioner by hand.
4) Remove the belt.
5) Remove the tensioner, tensioner plate, tensioner spring, and the spring damper.
6) Inspect the components thoroughly. Refer to the inspection points below.

To install:
1) Install the tensioner plate to the tensioner.
2) Install the tensioner assembly to the block but, do not torque down. Make sure that the arrow matches the plate movement.
3) Be sure that the timing marks are aligned.
4) Remove the cylinder head cover.
5) Loosen all the valve adjusting screws.
6) Install the timing belt with the tensioner spring and damper with the timing mark aligned and the tensioner pushed up.
7) With no slack, install the timing belt. Then put the tensioner stud in.
8) Turn the crankshaft two rotations clockwise after installing it. Make sure that there is no slack in the belt and torque the stud to 97 in. lbs. (11 Nm) and the tensioner bolt to 20 ft. lbs. (27 Nm).
9) Install the timing belt cover.
You're done weary travellers! :woot:
