Subjected to sustained 210°F–230°F operating conditions typical of the \u003cstrong\u003e3.6L Pentastar V6\u003c\/strong\u003e, OEM hoses experience micro-cracking, oil-induced softening, and structural fatigue. Under heavy thermal cycling or towing loads, factory lower hoses are especially prone to wall softening, which risks suction collapse under high-RPM water pump draw and subsequent rapid overheating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit upgrades the coolant circuit using multi-ply reinforced high-grade silicone paired with embedded heat-resistant fibers. Engineered to withstand continuous temperatures from -65°F up to 350°F and elevated burst pressures, the molded architecture maintains a high durometer rating to prevent vacuum collapse and ballooning under surge pressure. The ultra-smooth inner bore reduces fluid friction, resists coolant additive scale buildup, and prevents permeation leaks, while precision-molded factory bends ensure direct alignment with the OEM radiator outlets and thermostat housing without kinking.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e2011-2021 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;\"\u003e290-295 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2021 Jeep Grand Cherokee Laredo 3.6L V6 (WK2)\u003c\/li\u003e\n  \u003cli\u003e2011-2021 Jeep Grand Cherokee Limited 3.6L V6 (WK2)\u003c\/li\u003e\n  \u003cli\u003e2011-2021 Jeep Grand Cherokee Overland 3.6L V6 (WK2)\u003c\/li\u003e\n  \u003cli\u003e2012-2021 Jeep Grand Cherokee Summit 3.6L V6 (WK2)\u003c\/li\u003e\n  \u003cli\u003e2017-2021 Jeep Grand Cherokee Trailhawk 3.6L V6 (WK2)\u003c\/li\u003e\n  \u003cli\u003e2014-2021 Jeep Grand Cherokee Altitude \/ High Altitude 3.6L V6 (WK2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the WK2 Grand Cherokee?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2021 Jeep Grand Cherokee equipped with the 3.6L Pentastar V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan standard factory worm-drive clamps be reused with these silicone hoses?\u003c\/strong\u003e\u003cbr\u003e We recommend using lined hose clamps or constant-tension T-bolt clamps to prevent cutting into the outer silicone jacket under torque.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle severe off-road trails and heavy utility towing, this silicone kit ensures your Grand Cherokee cooling system maintains full hydraulic integrity under harsh ambient heat and demanding thermal loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502677856504,"sku":"DS-EGUS9TK0T","price":108.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/silicone-hose-kit-for-jeep-grand-cherokee-2011-2021-3-6l-1.jpg?v=1789348609","url":"https:\/\/performancechiptuning.com\/es\/products\/silicone-hose-kit-for-jeep-grand-cherokee-2011-2021-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
