Well with the 96-97 engines vigilance is a wise approach to take, don't forsake the timing belt maintenance routine.
If the engine has gone past 60,000 miles & the belt hasn't been replaced keep an eye on the belts condition on a regular basis. Pull off the front access cover & have a good look at the belts condition.
Look for debris under the belt, small black particles can be expected, anything on the large scale is a *red flag* to pull off the belt cover to get a look at whats lying in wait. Generally the belt will fail before the tensioner does, but the tensioner cannot keep the belt under *proper* tension if the belt has stretched too much, that's why there is a maintenance schedule on the belt.
