Over repeated thermal cycles, the OEM internal mechanical seals degrade, allowing pressurized coolant to seep through the weep hole onto the serpentine drive belt and surrounding accessory drive components. Furthermore, factory units suffer from cavitation and impeller blade erosion under prolonged load, causing diminished coolant velocity through the aluminum cylinder heads. This reduced thermal transfer capacity leads to localized hotspot formation, warped head surfaces, and premature head gasket breakdown under heavy towing or off-road conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a rugged, direct-replacement solution, this performance water pump housing is precision cast from high-grade aluminum alloy to resist thermal fatigue and micro-fracturing. It features a heavy-duty unitized mechanical seal paired with premium, low-friction dual-row bearings engineered to absorb severe belt tension and high rotational loads without deflection. The precision-balanced, corrosion-resistant internal impeller maximizes volumetric coolant flow rates across all RPM ranges, effectively mitigating coolant aeration and cavitational wear. Supplied with a reinforced direct-fit gasket, this assembly seals mating surfaces tightly against the engine block to withstand extreme operating pressures up to factory relief thresholds.\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 Mounting Gasket\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;\"\u003e2011-2015 Jeep Grand Cherokee\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;\"\u003e3.6L Pentastar V6 \/ WK2\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;\"\u003e290 hp \/ 260 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\u003e5184498AE\u003c\/strong\u003e, \u003cstrong\u003e5184498AH\u003c\/strong\u003e, \u003cstrong\u003e5184498AI\u003c\/strong\u003e, \u003cstrong\u003e5184498AD\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\u003e2011-2015 Jeep Grand Cherokee (WK2) 3.6L Pentastar V6\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 WK2 Grand Cherokee?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2015 Jeep Grand Cherokee equipped with the \u003cstrong\u003e3.6L Pentastar V6\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit 3.0L EcoDiesel, 5.7L HEMI, or 6.4L SRT V8 engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, the cooling system must be completely vacuum-filled or manually bled via the bleeder port to remove all air pockets and prevent immediate thermal air locking.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jeep Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle extreme trail crawling, sustained highway hauling, and high-ambient thermal stress, this heavy-duty cooling component ensures your WK2 retains consistent thermal regulation and uncompromised off-road reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545089343736,"sku":"DS-EIYFPRKT6","price":73.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-jeep-grand-cherokee-2011-2015-3-6l-1.jpg?v=1790716445","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-kit-for-jeep-grand-cherokee-2011-2015-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
