In severe cold, cold-cranking puts immense load on the starter motor and battery while promoting incomplete combustion and cylinder fuel wash down. The factory \u003cstrong\u003eWD\u003c\/strong\u003e cooling jacket lacks supplemental heating elements unless ordered with specific cold-weather packages, leaving critical iron block internals vulnerable to thermal shock and accelerated boundary lubrication wear during winter starts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 600-watt direct-immersion engine block heater inserts directly into the engine block core freeze plug cavity, submerging the heating element fully in the cooling jacket. Operating on standard 120V shore power, the element utilizes convective thermal transfer to continuously heat the coolant circuit, warming the cast-iron engine block, cylinder heads, and combustion chambers without idling. Featuring a durable 7-foot harness with a weather-resistant plug, this USA-made element withstands intense engine bay thermal cycling, vibrations, and road salt exposure while ensuring smooth, instant cold-weather starts.\u003c\/p\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;\"\u003e2011-2022 Dodge Durango\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;\"\u003e5.7L Hemi V8 \/ WD\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 \/ 390 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\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2022 Dodge Durango R\/T (5.7L Hemi V8)\u003c\/li\u003e\n  \u003cli\u003e2011-2022 Dodge Durango Citadel (5.7L Hemi V8)\u003c\/li\u003e\n  \u003cli\u003e2011-2022 Dodge Durango Crew \/ Special Service (5.7L Hemi V8)\u003c\/li\u003e\n  \u003cli\u003eFits 5.7L Hemi V8 applications only (Does not fit 3.6L V6, 6.4L 392, or 6.2L Hellcat)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the WD Durango?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2022 Dodge Durango equipped with the \u003cstrong\u003e5.7L Hemi\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhere does the heater element mount on the engine?\u003c\/h4\u003e\n\u003cp\u003eThe element presses directly into an OEM cylinder block freeze plug port to facilitate direct immersion in the coolant jacket.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Towing \u0026amp; Durability Standard\u003c\/h3\u003e\n\u003cp\u003eWhether navigating severe blizzards or hauling heavy payloads in freezing temperatures, keeping your \u003cstrong\u003eWD\u003c\/strong\u003e Durango's powertrain thermally primed protects internal bearings, extends starter motor life, and ensures optimal towing readiness.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67540377534712,"sku":"DS-EFJCHPXMS","price":175.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/engine-block-heater-for-dodge-durango-2011-2022-5-7l-hemi-1.jpg?v=1790659439","url":"https:\/\/performancechiptuning.com\/products\/engine-block-heater-for-dodge-durango-2011-2022-5-7l-hemi","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
