In tight midsize truck engine bays, high heat cycles cause the OEM unitized seals to harden, inducing coolant weep-hole leaks, system depressurization, and localized hot-spotting that risks head gasket compromise during sustained grade pulls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit water pump assembly features a precision-cast aluminum housing paired with a heavy-duty, hardened bearing assembly to resist radial play and belt-load fatigue. An optimized internal impeller profile promotes uniform coolant velocity and reduces cavitation at high RPM. Precision-machined mating surfaces and premium multi-layer seals ensure leak-free sealing under elevated cooling system pressures, while the matched thermostat assembly ensures tight thermal regulation.\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;\"\u003e2009-2012 Chevrolet Colorado\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;\"\u003e5.3L V8 (LH8 \/ LH9) \/ GMT355\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 hp \/ 320 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\u003e2009-2012 Chevrolet Colorado LT 5.3L V8\u003c\/li\u003e\n  \u003cli\u003e2009-2012 Chevrolet Colorado WT 5.3L V8\u003c\/li\u003e\n  \u003cli\u003e2009-2012 Chevrolet Colorado Z71 \/ ZQ8 5.3L 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 GMT355 Colorado?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2012 Chevrolet Colorado equipped with the \u003cstrong\u003eLH8\u003c\/strong\u003e or \u003cstrong\u003eLH9\u003c\/strong\u003e 5.3L V8 engine. \u003cstrong\u003eDoes not fit 2.9L LLV inline-4 or 3.7L LLR inline-5 engine configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the correct installation torque for the mounting hardware?\u003c\/h4\u003e\n\u003cp\u003eTorque the water pump bolts in a crisscross sequence to 11 lb-ft on the first pass and 22 lb-ft on the final pass to ensure a uniform seal.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Truck Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-demand towing and severe operating conditions, this cooling system component restores dependable heat rejection to keep your V8 truck on the road.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545108250872,"sku":"DS-E1CGQ5B8D","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-chevrolet-colorado-2009-2012-5-3l-1.jpg?v=1790716873","url":"https:\/\/performancechiptuning.com\/products\/performance-water-pump-kit-for-chevrolet-colorado-2009-2012-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
