can someone explain the how to put the timing belt back on the head without removing it or having to re do the timing
1) Set the #1 cylinder to TDC. (cam gear will have "UP" pointing up, the hash marks on the cam gear will be aligned with the top edge of the head, the rotor will point at the #1 spark plug wire, and the #1 piston will be all the way up)
2) Mark the timing belt / cam gear teeth orientation so when you reinstall the belt you're putting it back on the exact same way you took it off (a small amount of white out works great).
3) Half way down the lower timing belt cover is a hole plug. Pop it out to expose the tensioner bolt.
4) Loosen the tensioner bolt (14mm) about a half turn (don't remove it!!).
5) Use a long screw driver (with the tip wrapped in electrical tape) to push the tensioner down
just enough to be able to slip the timing belt off the cam gear.
6) Re-tighten the tensioner bolt.
To re-install the timing belt: As long as you didn't move the crank pulley, cam gear, or move the timing belt around a whole lot, you should be able to loosen the tensioner bolt up and slip the belt back on the exact same way it came off, using the exact same process used to remove it.
To re-tension the timing belt:
1) Put the timing belt back on as described.
2) With the tensioner bolt
still loose, rotate the crank pulley about an 1/8th to 1/4 turn CLOCKWISE.
3) Re-tighten the tensioner bolt.
4) Rotate the crank a couple full revolutions COUNTER-CLOCKWISE and set the #1 cylinder at TDC again.
5) Check to make sure the timing marks are aligned properly, if they are you're all done.
- Note: Your markings on the timing belt may not align with the markings on the cam gear after this.
If anything doesn't make sense just ask and I'll further clarify.
