Yes. Just did mine, it had 12k miles on it and was 6 years old. The potential damage that can happen if it snaps isn't worth it. It's rubber, rubber ages over time.

v-tach, as docwyte mentioned, since they are relatively old, you should take care of them. The effort you put forth now will save you volumes of pain and frustration, not to not to mention $$$$, down the road.
The first time is frustrating and time consuming, but with practice it becomes as easy as changing the oil. Take your time and make sure everything is lined up i.e. TDC is at TDC and the balance shafts are in alignment.
Side bar question, do the timing and balance shaft belts stretch that much? I over tightend my belts awhile back and drove them for a few hundered mile before I could get it to garage to double check my work. They told me that the belts were stretched and needed to be replaced. They were only about 500 mile old. Does this sound right?

I understand the retightening, but is it possible to stretch them so much that they need to be replaced? Granted the whined, but I did not go overboard with the initial tension.

I suppose its possible, but its is also possible that some mechanic wants 800 of your dollars too...but considering the consequences of a t-belt failure it is certainly worth looking into

"If the car is an 87 up with the automatic tensioner how do you retension it"
The Auto spring Tensioner is locked. You loosen the two M8 nuts (hinge and adjuster) so the tension can move. Then rotated the engine twice, ending back up at TDC to take up any addition belt stretch. Finally retighten "lock" the tensioner back in place.
