Message the tensioner to 4mm, THEN IT IS NOT SET CORRECTLY. You need to set the tensioner to the 4mm gap, not the other way around.

Please read Damon's writeup: [ http://www.ttzd.com/tech/timingbelttech.html ]

47. Shift the transmission to neutral. Put the crank bolt back in (make sure the thick washer is on it) & rotate the crank 2 times (720 degrees) clockwise to ensure the valves will not make contact with the pistons when the engine is started. Check the auto-tensioner's extension. It should be at about 4 mm. If it's not, put the retention bolt back in the auto-tensioner to remove tension on the belt. Slowly tighten the retaining bolt to relieve tension. If the retaining bolt is tightened too quickly, the casting on the tensioner will break. If it does, it's not a deal breaker. Just maintain tension on the belt and pry the backside of it instead of using the retaining bolt to retract the pulley. Loosen the two bolts and nut on the auto-tensioner, re adjust the position of the tensioner, tighten the bolts and nut again. Torque all to 12-15 ft-lbs. Release the retention bolt and go back to the start of this step. Repeat until the tension is correct.
