The OEM pump bearing assembly degrades over time from drive belt lateral load, compromising the internal mechanical shaft seal. This leads to telltale weep-hole fluid discharge, bearing play, and eventual impeller slippage. Furthermore, aging stamped factory impellers suffer from coolant cavitation at elevated RPMs, causing rapid aeration, localized hot spots in the cylinder heads, and premature thermostat binding that compromises engine longevity.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement pump assembly features a reinforced die-cast aluminum housing paired with a heavy-duty unitized shaft seal and high-load dual-bearing pack designed to withstand prolonged torsional belt loads. A high-efficiency internal impeller optimizes hydraulic volume flow across all four engine displacements, suppressing cavitation across the rev range. Supplied with a precision-calibrated thermostat housing and pre-formed multi-layer gaskets, this kit eliminates dry-seal leaks and interfaces seamlessly with the stock front accessory drive system to maintain exact coolant pressure dynamics.\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;\"\u003e2007-2013 GMC Sierra 1500\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;\"\u003eGen IV Vortec V8 \/ GMT900\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;\"\u003e295–403 hp \/ 305–417 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\u003e2007-2013 GMC Sierra 1500 4.8L V8 (LY2, L20)\u003c\/li\u003e\n  \u003cli\u003e2007-2013 GMC Sierra 1500 5.3L V8 (LH6, LY5, LMG, LC9)\u003c\/li\u003e\n  \u003cli\u003e2007-2009 GMC Sierra 1500 6.0L V8 (L76)\u003c\/li\u003e\n  \u003cli\u003e2009-2013 GMC Sierra 1500 6.2L V8 (L92, L9H, L94)\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 GMT900 Sierra 1500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2013 GMC Sierra 1500 equipped with the \u003cstrong\u003eGen IV Vortec\u003c\/strong\u003e 4.8L, 5.3L, 6.0L, or 6.2L engine.
