This is the OEM bolt that secures the lower part of your timing chain cover to the block. Part number 90021-PNA-000. It threads into the block and clamps the cover down so your timing chain stays sealed. When you're tearing into your timing chain for a replacement or you're doing front seals, you're pulling these bolts out. Don't throw old crusty bolts back in that've been torqued down for 100k miles. Fresh bolts torque right and your cover seals properly.\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why the Right Bolt Matters\u003c\/h4\u003e\n\n\u003cp\u003eTiming cover bolts keep your timing chain sealed inside the motor. Loose bolts mean your cover leaks oil everywhere. Bolts that're too long bottom out in the holes and the cover won't clamp down tight. You're leaking. Wrong thread pitch and you're just chewing up threads in your aluminum block. The OEM bolt's the right length and pitch for the lower cover spots. Don't dig through your bolt bin hoping something works. Get the right bolt and your cover seals up.\u003c\/p\u003e\n\n\u003ch4\u003eGoes in Two Lower Spots\u003c\/h4\u003e\n\n\u003cp\u003eThis bolt goes in the lower left and lower right positions on your timing chain cover. K series timing covers use different size bolts in different spots. They're not all the same. This one (90021-PNA-000) goes in the two bottom holes. If you're replacing all your timing cover bolts, you'll need different part numbers for the other spots. Check your cover and see how many bolts you've got and where they go. Don't assume they're all identical.\u003c\/p\u003e\n\n\u003ch4\u003eDifferent Spot on Newer Turbo Motors\u003c\/h4\u003e\n\n\u003cp\u003eHere's where it gets weird. On older K series motors (K20A, K20Z, K23A, K24A, K24Z), this bolt goes at the bottom left and bottom right of the cover. On newer turbocharged K series motors (K20C1, K20C2, K20C4, K20C9, K24W1, K24W7) - the ones in 10th and 11th gen Civics, Integra Type S, and newer TLX and RDX - this same bolt goes above the timing chain cover instead. Same part number, totally different spot. If you're working on a 2016+ turbo Honda or Acura, check your service manual so you know where this bolt actually goes.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHonda OEM lower timing cover bolt (part number 90021-PNA-000)\u003c\/li\u003e\n  \u003cli\u003eRight length and thread pitch for K series timing cover\u003c\/li\u003e\n  \u003cli\u003eSecures timing chain cover to engine block\u003c\/li\u003e\n  \u003cli\u003eGoes at lower left and lower right (older K series)\u003c\/li\u003e\n  \u003cli\u003eGoes above timing cover (newer turbo K series)\u003c\/li\u003e\n  \u003cli\u003eSame bolt your motor came with from the factory\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFits Your Car\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003e2013-2022 Acura ILX\u003c\/li\u003e\n  \u003cli\u003e2024-2026 Acura Integra Type S\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Acura RDX\u003c\/li\u003e\n  \u003cli\u003e2019-2025 Acura RDX\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Acura RSX\u003c\/li\u003e\n  \u003cli\u003e2015-2025 Acura TLX\u003c\/li\u003e\n  \u003cli\u003e2004-2014 Acura TSX\u003c\/li\u003e\n  \u003cli\u003e2003-2020 Honda Accord\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Honda Civic Si (EP3)\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Honda Civic Si\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Honda Civic DX\/EX\/LX\u003c\/li\u003e\n  \u003cli\u003e2012-2015 Honda Crosstour\u003c\/li\u003e\n  \u003cli\u003e2003-2011 Honda Element\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eCompatible Engines\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eOlder K Series (bolt goes at bottom left\/right of cover):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eK20A2, K20A3 (RSX, Civic Si EP3)\u003c\/li\u003e\n  \u003cli\u003eK20Z1, K20Z3 (RSX Type S, Civic Si)\u003c\/li\u003e\n  \u003cli\u003eK23A1 (RDX turbo 2007-2012)\u003c\/li\u003e\n  \u003cli\u003eK24A1, K24A2, K24A4, K24A8 (CR-V, TSX, Accord, Element)\u003c\/li\u003e\n  \u003cli\u003eK24Z1, K24Z2, K24Z3, K24Z7 (CR-V, Accord, TSX, Civic Si, ILX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNewer Turbo K Series (bolt goes above cover):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eK20C1, K20C2, K20C4, K20C9 (Civic Type R, Civic Si, Accord Sport)\u003c\/li\u003e\n  \u003cli\u003eK24W1, K24W7 (Integra Type S, TLX, RDX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually. Check how many you need for your cover. Older K series motors use this bolt at the bottom left and bottom right. Newer turbo K series (2016+) use it above the cover. When you're bolting your timing cover down, torque the bolts to spec in the right sequence (check your manual). Don't go crazy with the torque wrench or you'll strip threads in your aluminum block. Don't undertorque them either or your cover's gonna leak. Use a torque wrench, not an impact gun. If you're doing a timing chain job, replace the chain, tensioner, guides, and all the cover bolts together. Don't mix old and new stuff. Slap a thin bead of Hondabond or RTV on the cover mating surface before you bolt it down. Let the RTV set up for however long Honda says before you fill it with oil and fire it up.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003c\/li\u003e\n\u003cli\u003e2013-2022 Acura ILX\u003c\/li\u003e\n  \u003cli\u003e2024-2026 Acura Integra Type S\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Acura RDX\u003c\/li\u003e\n  \u003cli\u003e2019-2025 Acura RDX\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Acura RSX\u003c\/li\u003e\n  \u003cli\u003e2015-2025 Acura TLX\u003c\/li\u003e\n  \u003cli\u003e2004-2014 Acura TSX\u003c\/li\u003e\n  \u003cli\u003e2003-2017 Honda Accord (K24)\u003c\/li\u003e\n\u003cli\u003e2018-2022 Honda Accord 2.0T\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Honda Civic Si (EP3)\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Honda Civic Si\u003c\/li\u003e\n  \u003cli\u003e2006-2015 Honda Civic DX\/EX\/LX\u003c\/li\u003e\n\u003cli\u003e2002-2019 Honda CR-V\u003c\/li\u003e\n  \u003cli\u003e2012-2015 Honda Crosstour\u003c\/li\u003e\n  \u003cli\u003e2003-2011 Honda Element\u003c\/li\u003e \n\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\nSize: M6x31mm\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Lower Timing Cover Bolt\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Honda","offers":[{"title":"Default Title","offer_id":45201141923874,"sku":"OHA-90021-PNA-000","price":5.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/OHA-90021-PNA-000_udot.jpg?v=1775578830","url":"https:\/\/www.hybrid-racing.com\/products\/honda-k-series-timing-cover-bolt-90021-pna-000","provider":"Hybrid Racing","version":"1.0","type":"link"}
