Over time, the OEM cartridge-style shaft bearing fatigues, causing mechanical seal breakdown and telltale weep hole coolant leakage. In sustained high-temperature operating conditions, factory impeller tolerances degrade, leading to cavitation, localized hot spots, and reduced fluid velocity across the cylinder block. Unaddressed shaft play compromises the front accessory drive, increases serpentine belt wear, and risks sudden impeller seizure on high-mileage \u003cstrong\u003eL20\u003c\/strong\u003e (4.8L) and \u003cstrong\u003eL96\u003c\/strong\u003e (6.0L) powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit water pump assembly is cast from high-density aluminum alloy to maintain structural rigidity under extreme thermal stress. Outfitted with heavy-duty, heat-treated steel roller bearings and a precision unitized dynamic seal, it eliminates coolant blow-by and shaft deflection. The balanced cast impeller ensures uniform, high-volume fluid dynamics throughout the engine block and radiator cores. Paired with a pre-assembled thermostat and OE-profile replacement gaskets, this kit guarantees an airtight seal, rapid warm-up cycling, and sustained operating temperature stabilization under heavy fleet payloads.\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;\"\u003e2007-2020 GMC Savana 2500,3500\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 4.8L (L20), 6.0L (L96\/LY6) \/ GMT610\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;\"\u003e279-342 hp \/ 295-373 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;\"\u003e12681417, 12600767, AW6009\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\u003e2007-2020 GMC Savana 2500 (4.8L V8, 6.0L V8)\u003c\/li\u003e\n  \u003cli\u003e2007-2020 GMC Savana 3500 (4.8L V8, 6.0L V8)\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 GMT610 Savana 2500,3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2020 GMC Savana 2500 and 3500 equipped with the \u003cstrong\u003e4.8L\u003c\/strong\u003e or \u003cstrong\u003e6.0L\u003c\/strong\u003e Vortec V8 engines. \u003cstrong\u003eThis kit does not fit 4.3L V6, 6.6L Duramax diesel, or 2.8L turbo-diesel engine configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat torque specifications should be used during installation?\u003c\/h4\u003e\n\u003cp\u003eFasteners must be torqued to vehicle manufacturer specifications (typically 11 lb-ft on the first pass, 22 lb-ft on the final pass) in a crisscross pattern to prevent housing distortion.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Savana Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the constant thermal abuse of severe towing, maximum GVWR hauling, and stop-and-go fleet routes, this water pump kit delivers reliable hydraulic efficiency to keep your truck running cool under maximum payload demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545116246264,"sku":"DS-EWH8WBFMS","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-gmc-savana-2500-3500-2007-2020-4-8l-6-0l-1.jpg?v=1790717096","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-kit-for-gmc-savana-2500-3500-2007-2020-4-8l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
