The factory stamped-steel or composite impellers degrade over time, dramatically reducing coolant flow velocity across the cylinder heads of the \u003cstrong\u003eVortec 6000 (LQ4)\u003c\/strong\u003e. Simultaneously, the factory spring-loaded belt tensioner loses damping rate due to internal spring fatigue. This slack leads to parasitic micro-slippage of the serpentine belt, causing accessory drag, accelerated pulley groove wear, erratic alternator output, and elevated operating temperatures under sustained load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service assembly pairs a precision-cast, heat-treated aluminum water pump housing with a reinforced internal bearing assembly designed to handle severe side-load stress. Fitted with an efficient, balanced impeller, it maintains optimal coolant flow dynamics without cavitation at elevated RPM. The kit includes a pre-calibrated mechanical thermostat to ensure precise thermal regulation, alongside an OE-spec heavy-duty belt tensioner assembly engineered with a high-tensile internal spring to maintain constant belt contact. Completed with precision-molded EPDM serpentine and A\/C belts, this package replaces common failure points with direct OE interchange units (including \u003cstrong\u003e12580162\u003c\/strong\u003e and \u003cstrong\u003e12609719\u003c\/strong\u003e) for reliable heat rejection under severe duty.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2000-2006 GMC Yukon XL 2500\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eVortec 6000 (LQ4) \/ GMT830\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e300-335 hp \/ 360-375 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e12580162, 12609719, 12560380, 12562458, 12703898, 19195104\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2001 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2002 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2003 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2004 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2005 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2006 GMC Yukon XL 2500 SLE \/ SLT 6.0L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT830 Yukon XL 2500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2006 GMC Yukon XL 2500 equipped with the Vortec 6000 (LQ4) engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre new water pump gaskets and thermostat included in this kit?\u003c\/h4\u003e\n\u003cp\u003eYes, the assembly includes a pre-assembled thermostat, mounting hardware, and all required premium die-cut gaskets and O-rings for a leak-free seal.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the rigorous demands of three-quarter-ton hauling and continuous heavy-payload towing, this cooling assembly ensures your 3\/4-ton chassis resists overheating across steep grades and high ambient conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67544668406008,"sku":"DS-EP8RKDCI7","price":193.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-gmc-yukon-xl-2500-2000-2006-6-0l-1.jpg?v=1790708665","url":"https:\/\/performancechiptuning.com\/products\/performance-water-pump-kit-for-gmc-yukon-xl-2500-2000-2006-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
