its supposed to auto-tension
can anyone elaborate how to properly set the tension for the timing belt; i have the 2 pin tool; torque wrench....i been reading the fsm but i can't connect why im using this tool and how do I know tension is correct on the belt
same deal for the balance shaft belt
U have to compress the tensioner and slide the pin in, then once u have the tensioner in place pull the pin

Here is the deal.
First off, leave the grenade pin in the hydraulic auto-tensioner. If you already took it out, remove the tensioner, compress it in a vise and put the pin back in. If you lost the pin, you can use any type of pin or strong nail to hold it.
Regarding the actual belt tension when using the two prong tensioner tool. Essentially your supposed to put that tool onto a 1/4" drive torque wrench and turn the wrench until it clicks, hold it there and use a socket to tighten the bolt down to lock the tensioner pulley into place. I have never used a torque wrench for this, I always do it by feel. I have done it more than a dozen times so I just sorta know where it should be. You can use the two prong holes in the tensioner pulley as a reference point. This is after I installed the timing belt on my old EVO motor.
Once you get the tensioner set. Rotated the engine over twice. Two complete revolutions. Now grab the grenade pin the hydraulic tensioner, pull on it slowly. It should move with very little effort, if this is the case, you did it right. If the grenade pin doesnt want to come out and requires force, you didnt tighten the tensioner pulley enough. The idea behind the hydraulic autp-tensioner is this. As the timing belt wears and stretches, it takes up the slack by pushing the arm that the tensioner pulley is on UP, which puts more tension on the belt. So the idea is, you need to set the initial tension correctly or very close to correctly, or as the belt starts the wear you might run into trouble
