Sub-zero temperatures severely elevate motor oil viscosity, stalling initial oil pressure to the overhead valvetrain, camshaft journals, and Multi-Displacement System (MDS) lifters during ignition. Extended cranking under cold oil friction accelerates cylinder bore scuffing, drains battery reserves, strains the starter drive, and creates rich-condition cylinder washdown before the powertrain control module achieves closed-loop status.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 600-watt, 120-volt block heater utilizes a direct-immersion design that seats directly into the factory engine core plug port. By submerging a corrosion-resistant heating element into the internal water jacket, it establishes natural thermal siphon convection throughout the cylinder block and heads. This conductive heat migration keeps the oil galleries warm, preventing starvation at the roller lifters upon start-up and eliminating cold-cranking drag. Built with a solid brass retaining body to resist electrochemical corrosion, it features a heavy-duty, silicone-insulated 7-foot power cord routed safely from high-temperature exhaust headers to an external 120V standard outlet.\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;\"\u003e2005-2008 Dodge Magnum\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 \/ LX\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;\"\u003e340 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\u003e2005-2008 Dodge Magnum R\/T (5.7L HEMI V8, RWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003eNote: Incompatible with 2.7L V6, 3.5L V6, and 6.1L SRT8 models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the LX Magnum?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2008 Dodge Magnum equipped with the 5.7L HEMI engine.\u003c\/p\u003e\n\n\u003ch4\u003eDoes installing this block heater require draining the cooling system?\u003c\/h4\u003e\n\u003cp\u003eYes, the cooling system must be partially drained because the heating element mounts directly into an engine block freeze plug port.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eKeep your Hemi powerplant firing instantly in harsh winter conditions, ensuring rapid oil circulation to maintain mechanical integrity and deliver immediate V8 torque when you turn the key.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67540382220536,"sku":"DS-EG436ROAN","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-magnum-2005-2008-5-7l-hemi-1.jpg?v=1790659465","url":"https:\/\/performancechiptuning.com\/fr\/products\/engine-block-heater-for-dodge-magnum-2005-2008-5-7l-hemi","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
