Gates Micro-V Serpentine Belt - 2012-2015 Honda Civic Si / 2013-2015 Acura ILX (K24Z7)
Hearing a squeal on cold startup, or just due for some maintenance on your Si or ILX? Your serpentine belt is worth a look. On the K24Z7 in the 9th gen Civic Si and the 2013-2015 Acura ILX 2.4L, one single belt drives your alternator, power steering pump, and A/C compressor, so when it wears out and fails, it takes all three down with it at once, no charging, no power steering, no A/C, usually at the worst possible time. This is the Gates K070667, an OEM-spec Micro-V replacement that matches Honda part 31110-RX0-A01, so you're putting your belt back to factory and keeping everything spinning.
Why This Is The Belt To Buy
Here's something a lot of people don't realize: Gates is one of Honda's actual OEM belt suppliers, so this isn't an aftermarket belt reverse-engineered to look like the factory one, it's built to the same spec Honda hands out. The K070667 is a 7-rib Micro-V belt at about 66.7" outside length, made from EPDM rubber with an aramid fiber cord. That construction is what gives you low stretch, high heat resistance, and a long service life, exactly what you want from a belt that has to keep three accessories turning in a hot engine bay for years. Gates rates it to meet or exceed SAE J1459, J2432, and J1596, so it's not cutting any corners to hit a price.
How To Tell When It's Actually Worn
This is worth knowing, because these modern belts fool people. The old neoprene belts used to crack and fray when they were done, so you could spot a bad one at a glance. EPDM belts like this one don't really do that, instead the ribs slowly lose material depth while the belt still looks fine. That's why a belt wear gauge (cheap, available at most parts stores) is the reliable way to check yours. Most techs say inspect it around 60,000 miles and replace it by 100,000, or whenever the ribs are worn down to the gauge indicators. If you're already in there and yours has some miles on it, just put the new one on and reset the clock.
Check The Tensioner And Idler While You're In There
Don't just swap the belt and call it done, take two minutes to check what spins it. Grab the idler pulley and spin it by hand, feeling for any roughness or bearing play, and make sure your tensioner arm still has real spring resistance and isn't bottomed out. The 9th gen Si uses an automatic tensioner, so there's nothing to manually adjust, but a weak one won't hold proper tension, and that's what causes belt squeal and chews up a new belt early. If the tensioner feels tired, replace it along with the belt so your fresh Gates belt actually lasts.
Easy Install
Good news, this is about a 20-minute job with basic hand tools. Release the automatic tensioner, slip the old belt off, route the new one according to the diagram on the sticker under your hood, and let the tensioner back down onto the belt. That's it. Just double-check your routing against the diagram before you let the tensioner go, since a belt that's off by one pulley won't drive everything right.

Note: Gates K070667 Micro-V serpentine drive belt for the 2.4L K24Z7 in the 2012-2015 Honda Civic Si (FB6/FG4) and 2013-2015 Acura ILX. A 7-rib belt at approximately 66.7" (1694mm) outside length, made from EPDM rubber with an aramid fiber cord for low stretch, heat resistance, and long life, and rated to meet or exceed SAE J1459, J2432, and J1596. Cross-references Honda part number 31110-RX0-A01. This belt fits the 2.4L K24Z7 only: the base 9th gen Civic with the 1.8L R18 and the 2.0L ILX both use different belts, so confirm you have the Si or the ILX 2.4L before ordering. Inspect the tensioner and idler pulley when replacing the belt and replace a weak automatic tensioner alongside it. One belt per order.
