Sustained high-thermal cycles and heavy towing loads accelerate impeller degradation and cause factory thermostat housings to warp, resulting in coolant loss, air ingress, and severe localized cylinder head hot spots.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit replacement water pump features a reinforced cast-aluminum housing and a dynamically balanced impeller engineered to maximize volumetric flow and eliminate coolant cavitation across all RPM bands. Fitted with severe-duty ceramic shaft seals, high-load industrial bearings, and precision-stamped porting, this assembly resists shaft deflection and pressure spikes. The matched thermostat unit and high-temp elastomeric gaskets deliver a leak-free seal without requiring RTV silicone.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Engine Water Pump\u003c\/li\u003e\n  \u003cli\u003e1 Thermostat Housing\u003c\/li\u003e\n  \u003cli\u003e1 Thermostat\u003c\/li\u003e\n  \u003cli\u003e2 Rectangular Gaskets\u003c\/li\u003e\n  \u003cli\u003e1 Oval Gasket\u003c\/li\u003e\n  \u003cli\u003e2 Mounting Bolts\u003c\/li\u003e\n\u003c\/ul\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: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2007-2009 Hummer H2\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;\"\u003e6.0L LQ4, 6.2L L92 \/ \u003cstrong\u003eGMT820\u003c\/strong\u003e\n\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;\"\u003e325-393 hp \/ 365-415 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;\"\u003e\n\u003cstrong\u003e12681417\u003c\/strong\u003e, \u003cstrong\u003e12600767\u003c\/strong\u003e, \u003cstrong\u003eAW6009\u003c\/strong\u003e\n\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\u003e2007 Hummer H2 SUV \/ SUT (6.0L V8 LQ4)\u003c\/li\u003e\n  \u003cli\u003e2008 Hummer H2 SUV \/ SUT (6.2L V8 L92)\u003c\/li\u003e\n  \u003cli\u003e2009 Hummer H2 SUV \/ SUT (6.2L V8 L92)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT820 H2?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2009 Hummer H2 equipped with the \u003cstrong\u003e6.0L LQ4\u003c\/strong\u003e or \u003cstrong\u003e6.2L L92\u003c\/strong\u003e Vortec engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the proper installation procedure for this pump assembly?\u003c\/h4\u003e\n\u003cp\u003eTorque all pump-to-block fasteners to factory specification in two passes (11 lb-ft initial, 22 lb-ft final) and perform a thorough cooling system vacuum bleed to eliminate air pockets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hummer Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to match the brutal thermal demands of heavy vehicle payloads and demanding overland trails, providing continuous cooling efficiency where standard replacement units fail.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545120440568,"sku":"DS-E3VFXKLCL","price":108.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-hummer-h2-2007-2009-6-0l-6-2l-1.jpg?v=1790717219","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-water-pump-kit-for-hummer-h2-2007-2009-6-0l-6-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
