Thanks, y'all for your thoughts about T-belt replacement interval. Since the engine designers at Chrysler thoughtfully provided a T-belt inspection window in the outer cover, I'll use it to inspect the T-belt as often as I change engine oil and filter, and rotate the wheels. I'll take coupla photos and upload an on-vehicle service note about T-belt inspection in the next few days.
