This billet coolant block off plate from Fleece Performance is built to solve that problem with confidence and keep it from coming back. The factory plate is known to weaken over time, which leads to seepage and repeat repairs that no one wants to deal with. This upgraded design is thicker and far more durable, giving you peace of mind every time you fire up your truck. Additionally, the integrated O-ring eliminates the need for a traditional gasket, which is often the weak point in sealing surfaces. Installation is straightforward, making it an easy upgrade when you are already working in that area of the engine. Once installed, you can count on a tighter seal and a cleaner engine bay without the constant worry of leaks. It is a simple upgrade that makes a noticeable difference in long term reliability.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machined Upgrade Designed For Long Term Sealing Performance\u003c\/h4\u003e\n\u003cp\u003eBuilt from high quality billet aluminum, this coolant block off plate is engineered to outperform the stock stamped component in both strength and sealing capability. The increased thickness adds rigidity, which helps maintain consistent clamping force across the sealing surface under heat and pressure. Furthermore, the integrated square cut O-ring is designed to provide a more reliable seal compared to traditional flat gaskets that can degrade over time. This design reduces the chances of coolant seepage, especially in high mileage or heavily used engines. It is a direct replacement for OEM part numbers 97941204 and 12698239, ensuring proper fitment on 2001-2025 GM Silverado and Sierra 2500HD and 3500HD models equipped with the 6.6L Duramax. The precision machining process ensures a tight, accurate fit that aligns perfectly with factory mounting points. Corrosion resistance is another key benefit, helping the plate hold up in harsh engine bay conditions. Backed by a one year limited warranty, this component delivers both performance and confidence where it matters most.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eReplaces known leak-prone factory rear cover plate\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for Duramax rear engine location\u003c\/li\u003e\n\u003cli\u003eUses integrated O-ring instead of traditional gasket\u003c\/li\u003e\n\u003cli\u003eEnsure proper surface cleaning before installation\u003c\/li\u003e\n\u003cli\u003eDirect replacement for OEM part numbers listed\u003c\/li\u003e\n\u003cli\u003eCompatible with multiple Duramax model years\u003c\/li\u003e\n\u003cli\u003eIdeal during rear engine or transmission service\u003c\/li\u003e\n\u003cli\u003eBillet design differs from factory stamped steel\u003c\/li\u003e\n\u003cli\u003eCheck O-ring condition before final install\u003c\/li\u003e\n\u003cli\u003eCovered by one year limited parts warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fleece Performance Products","offers":[{"title":"Default Title","offer_id":54039381901596,"sku":"FLCFPE-DMAX-CBOP","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/plate1.jpg?v=1776182584","url":"https:\/\/www.alligatorperformance.com\/products\/fleece-fpe-dmax-cbop-billet-coolant-block-off-plate-2001-2025-gm-silverado-sierra-2500hd-3500hd-6-6l-duramax","provider":"Alligator Performance","version":"1.0","type":"link"}
