Re: I have this 89 acura legend 2.7l v6 timing belt...
Hi, here is what you need to do. Get all of the timing marks lined up as indicated in the picture below. Put the belt on. Without moving the gears off their marks, make the belt tight across the cam gears and then down the right side to the crank gear. All of the slack must be on the left side to be taken up by the tensioner. Release the tensioner to tighten the belt and then verify the marks are still aligned. If the marks are not aligned, loosen the tensioner just enough to turn the gear that needs to be realigned. After tensioning the belt, rotate the crankshaft clockwise 720 degrees and recheck the timing marks. I have pasted the book procedure below. Please let me know if you still have questions. You must get this right.

If the crankshaft or camshafts have been turned with the timing
belt removed, remove the spark plugs and advance the crankshaft about 15
degrees beyond TDC of No. 1 cylinder. Make sure the camshaft sprockets
are properly aligned with the marks and return the crankshaft to the TDC
mark.

Install the belt in sequence on the crankshaft, the front camshaft, water pump and tensioner pulleys, then the rear camshaft.

To adjust the tension, loosen the tensioner pulley bolt about

turn. The spring will automatically set the proper tension. Torque the bolt to 31 ft. lbs. (43 Nm).

Rotate the crankshaft 6 turns clockwise and check that the timing
marks on the crankshaft and camshafts align properly. Adjust the timing
belt tension again by rotating the crankshaft to the align the blue mark
on the pulley with the pointer. Loosen and retorque the tensioner
pulley bolt.

Install the remaining parts in reverse order. Torque the
crankshaft pulley bolt to 83 ft. lbs. (115 Nm). When installing the side
mount bracket, torque the bolts to 40 ft. lbs. (55 Nm).
