I replaced my sister's timing belts three months ago with NAPA's belts and her's are still in tack. Funny, same side too. hmmmmm....

Hmmm ... how should the timing belt be tensioned? Yeah, his idlers were good. He's a machinist so he just replaced all the bearings in the idlers.

Below is photo of a tool I made to adapt a torque wrench to the cam sprocket (instead of the special Subaru tool #499437000). Welded in the center of the tool is an all thread rod coupling (just like a hex nut, only longer). (FYI - The little thing to the right in the photo is a flywheel stopper I made).
After using it a few times, I could probably tension the belt properly without a torque wrench (within the variability that you'd get with a torque wrench due to adjuster stiction and other variables). It's moderately taut, but bbitner is correct - it's definitley not nearly as tight as you'd tighten a V-belt.
(A word of caution - make sure your torque wrench works in the CCW direction - some of the cheap click type ones only click in the CW direction - after all - how many times have you torqued a left-hand thread? - I didn't realize this the first time I used my adapter tool and it's a wonder I didn't break something because I kept pulling harder and harder on the wrench because it never clicked before I finally figured out it wasn't going to click in that direction. BTW - nothing wrong with click-type torque wrenches - I prefer them - my point was the *cheap* ones may only work in one direction)
