On the 10th-gen Accord the serpentine belt job is more about access than about the belt itself. Both turbo engines use one short belt running the alternator and A/C compressor off the crank pulley, with a self-adjusting spring tensioner, so there is nothing to measure or adjust. The catch is that the belt lives behind the passenger-side wheel and inner fender liner, so the real work is pulling a wheel and a dozen 10 mm bolts and plastic clips before you ever touch a pulley.
What varies is the engine. The 1.5T and 2.0T take different belts, so order by VIN rather than by year. The hybrid takes no belt at all. The mistake people make most often is not verifying the belt is fully seated in every groove before lowering the car — a belt sitting one rib off will chirp, shred and throw itself within a few miles. Take thirty seconds with a mirror and a light.

1.5T (L15BE) and 2.0T (K20C4) use the same tool sizes — 19 mm lugs, 10 mm/8 mm liner fasteners, 14 mm tensioner pulley bolt — but the belts are different lengths and rib counts, so match the part to the VIN. The 2.0L Accord Hybrid (LFA) has no accessory drive belt, no tensioner and no alternator, so no tools apply.

No. The hybrid's 2.0L Atkinson engine uses an electric A/C compressor and motor-generators in place of an alternator, so there is no accessory drive belt, pulley or tensioner to service.'
Practically, yes. You can sometimes get a hand on the tensioner from below with the under-tray off, but with the right front wheel and inner fender liner out of the way the job takes minutes instead of an hour of cursing.
Honda calls for inspection at regular services rather than a fixed replacement interval; most owners replace it around 90,000-100,000 miles or sooner if it shows cracks across the ribs, glazing, missing chunks or chirping on cold start.
A 14 mm socket on the tensioner pulley center bolt, on a long 3/8-inch ratchet or a serpentine belt tool. Confirm it on your car before you buy a tool — and note the tensioner only moves in one direction, so don't force it the wrong way.
