The stock water pump mechanical shaft seals degrade over time, leading to weeping coolant leaks from the weep hole, premature bearing play, and eventual impeller slippage. Furthermore, the OEM thermostat assembly suffers from spring fatigue and stiction, preventing proper coolant bypass to the radiator and driving operating temperatures into critical zones.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct replacement water pump assembly utilizes a heavy-duty cast aluminum housing engineered for maximum thermal heat dissipation. Internally, a precision-balanced impeller maximizes coolant flow rates through the block and heads without cavitating at elevated RPMs. High-temperature unitized mechanical shaft seals and heavy-duty dual-row bearings prevent fluid migration and runout under drive-belt loads. Supplied with high-grade replacement gaskets and a pre-calibrated thermostat housing, this kit delivers reliable cooling line pressure and restores tight closed-loop thermal control.\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;\"\u003e2007-2019 Chevrolet Silverado 2500 HD, 3500 HD\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;\"\u003e\n\u003cstrong\u003e6.0L Vortec (L96\/LY6)\u003c\/strong\u003e \/ \u003cstrong\u003eGMT900, K2XX\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;\"\u003e360 hp \/ 380 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\u003e2007-2019 Chevrolet Silverado 2500 HD 6.0L V8\u003c\/li\u003e\n  \u003cli\u003e2007-2019 Chevrolet Silverado 3500 HD 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 GMT900 and K2XX Silverado HD?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2007-2019 Chevrolet Silverado 2500 HD and 3500 HD equipped with the \u003cstrong\u003e6.0L V8\u003c\/strong\u003e engine; verify your engine displacement before purchasing as it does not fit 6.6L Duramax diesel models.\u003c\/p\u003e\n\n\u003ch4\u003eWhat torque specification should be used for the water pump mounting bolts?\u003c\/h4\u003e\n\u003cp\u003eTighten the water pump mounting bolts to the factory GM specification in two passes—11 lb-ft on the first pass and 22 lb-ft on the final pass—to ensure an even gasket seal.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eSilverado HD trucks are purpose-built to shoulder demanding industrial payloads and severe-duty towing cycles.
