In the \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e, cold dry starts accelerate wear on the hydraulic lifters, camshaft lobes, and cylinder walls. Additionally, extended open-loop idle enrichment causes unburnt fuel wash against the cylinder bore, reducing lubrication efficacy and drastically increasing tailpipe emissions during the warmup cycle.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 600-watt direct-immersion cartridge integrates directly into the water jacket freeze plug port of the \u003cstrong\u003e5.7L HEMI V8\u003c\/strong\u003e. Powered by a standard 120V grounded supply, the heating element initiates natural thermal convection throughout the cooling passages, warming both the engine block and internal fluid reserves prior to ignition. Constructed with high-grade copper heating sheathing and a weather-sealed 7-foot heavy-gauge automotive power harness, it withstands thermal cycling, road salt, and chassis vibration without degrading.\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: solid font-size: min-width:\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 Ram 1500, 2500, 3500\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 (Eagle) \/ DS, DT, DJ\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;\"\u003e395 hp \/ 410 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 Ram 1500 with 5.7L Hemi V8\u003c\/li\u003e\n  \u003cli\u003e2011-2022 Ram 2500 with 5.7L Hemi V8 (Gas models only)\u003c\/li\u003e\n  \u003cli\u003e2011-2022 Ram 3500 with 5.7L Hemi V8 (Gas models only)\u003c\/li\u003e\n  \u003cli\u003eDoes not fit 3.6L Pentastar V6, 3.0L EcoDiesel, 6.4L Hemi, or 6.7L Cummins Diesel\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the DS and DT 1500, 2500, 3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2022 Ram 1500, 2500, and 3500 equipped with the \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDoes installation require draining the cooling system?\u003c\/h4\u003e\n\u003cp\u003eYes, because the element mounts directly into the engine block core plug port, coolant must be drained prior to removing the OEM freeze plug.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for rigorous commercial duty cycles, fleet hauling, and severe-duty towing, this block heater ensures your Ram platform cranks instantly under extreme sub-zero weather conditions while preserving long-term valvetrain integrity.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67539521077496,"sku":"DS-EOVV8ZBTH","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-ram-1500-2500-3500-2011-2022-5-7l-hemi-1.jpg?v=1790650487","url":"https:\/\/performancechiptuning.com\/products\/engine-block-heater-for-ram-1500-2500-3500-2011-2022-5-7l-hemi","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
