It is an interesting idea, possibly useful for every second belt replacement when you are NOT replacing the tensioner. It would be more useful on engines with floating tensioners that do not have a tensioner lock hole.

1) Remove spark plugs and pull off your front covers and the vibration dampener exposing the timing belt.

2) Turn your engine by hand to line up the timing marks to check for proper cam to crank timing just in case the timing belt jumped a tooth or two. (On a brick, loosen the tensioner bolt.)

3) With a utility knife, cut the old belt lengthwise, down the middle, all the way around. What you are doing is creating two belts. After you have cut all the way around, cut the front half of the belt off and remove it from the pulleys.

4) Slide your new belt on the pulleys and push on as far as it will go against the other half of the old belt. Once the new belt is on, cut the second half of the old belt off, then slide the new belt the rest of the way on the pulleys. (On a brick, tighten the tensioner bolt) Put your covers back on and you are good to go.
