Gates Micro-V Serpentine Belt - 2005-2006 Acura RSX Type-S (K20Z1)
One belt, three jobs. On your 05-06 RSX Type-S, a single serpentine belt spins your alternator, power steering pump, and A/C compressor off the K20Z1, so when it finally gives up, you don't lose one of those, you lose all three at once, usually somewhere inconvenient. And here's the thing nobody wants to hear: your RSX isn't getting any younger. If it's still on its original belt, that rubber's been working hard for two decades, and it's living on borrowed time whether it looks fine or not. This is the Gates K070669, an OEM-spec Micro-V replacement that matches Acura part 38920-PRC-014, so you can knock it out before it leaves you stranded.
Why You Want The Gates One
Quick reason this is the belt to grab: Gates actually supplies belts to Honda from the factory, so you're not rolling the dice on some no-name belt that's a rough copy, you're getting the real deal. The K070669's a 7-rib Micro-V at 67-1/2" outside length, built from EPDM rubber on an aramid fiber cord. That EPDM takes heat and resists cracking way better than the old neoprene belts ever did, and the aramid cord barely stretches, so your tension stays consistent the whole life of the belt. Each one's individually form-ground for tight dimensional control too, which is what keeps it quiet and gripping the pulleys right instead of squealing. Gates rates it to meet or beat SAE J1459, J2432, and J1596, so it's not cutting corners to hit a price.
Here's How You Actually Know It's Worn
Pay attention to this, because these belts are sneaky. The old neoprene belts cracked and frayed when they were done, so you could spot a bad one at a glance. EPDM belts like this don't really do that, they just quietly wear the ribs down thinner over time while the belt looks totally fine from the top. So by the time you hear it squealing, it's already slipping on the pulleys. A belt wear gauge is the reliable way to check rib depth, but honestly, on a 20-plus-year-old RSX still wearing its original belt? Don't overthink it, just put the new one on and reset the clock.
While You're In There, Check What Spins It
Do yourself a favor and don't just throw the belt on and walk away. Spin your idler pulley by hand and feel for any roughness or bearing noise, and make sure your tensioner still pushes back with real spring and isn't bottomed out. Here's why it matters: those parts are the same age as the belt you're replacing, and a tired tensioner will chew through your brand-new belt and have it squealing in no time. If yours feels weak, swap it while you're already in there. Do it all at once and you're not pulling this job apart twice.
Putting It On
Good news, this is a quick one, about 15 to 20 minutes with basic hand tools. Find the routing diagram on the sticker in your engine bay (don't try to do it from memory), release the tensioner, slip the old belt off, route the new one exactly per the diagram, and let the tensioner back down onto it. Give your routing one last look before you release the tensioner, since a belt that's off by a single pulley won't drive everything right.
Make Sure You've Got The Right Year
This is the one to read before you order, because the RSX has a few different belts and they're not interchangeable. This belt is for the 2005-2006 facelift RSX Type-S with the K20Z1, that car specifically. The earlier 2002-2004 Type-S runs the K20A2 and uses a different belt, and the base RSX with the K20A3 is a different part number too. So before you buy, make sure you're on an 05-06 Type-S. If you are, this is your belt.

A 7-rib belt at 67-1/2" (1714mm) outside length, made from EPDM rubber with an aramid fiber cord for low stretch, heat resistance, and consistent tension, and individually form-ground for precise dimensional control and quiet operation. Rated to meet or exceed SAE J1459, J2432, and J1596. Cross-references Acura part number 38920-PRC-014. This belt fits the 2005-2006 facelift RSX Type-S (K20Z1) only; the 2002-2004 Type-S (K20A2) and the base RSX (K20A3) use different belts, so confirm your year and trim before ordering. Inspect the tensioner and idler pulley when replacing the belt and replace a weak tensioner alongside it. One belt per order.
