On the transverse \u003cstrong\u003eLFX\u003c\/strong\u003e 3.6L V6, the factory alternator is exposed to severe radiant heat soak from adjacent exhaust routing. Over time, thermal cycles degrade the internal diode rectifier and wear down the carbon slip-ring brushes, triggering intermittent battery warning lights, flickering headlights, and parasitic discharge that leaves the battery undercharged.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to original specifications, this brand-new unit features a die-cast aluminum housing with integrated high-efficiency cooling fans (IF) and an internal solid-state voltage regulator (IR) designed to survive high underhood thermal thresholds. Utilizing precision copper field windings, a heavy-duty rectifier bridge, and a factory-matched 6-groove clockwise pulley, it bolts directly to the engine cradle brackets and connects to the factory 2-pin harness without modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Alternator 12V 150A\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;\"\u003e2017-2020 Chevrolet Impala\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;\"\u003e\n\u003cstrong\u003eLFX\u003c\/strong\u003e 3.6L V6 \/ \u003cstrong\u003eEpsilon II\u003c\/strong\u003e\n\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;\"\u003e305 hp \/ 264 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;\"\u003e11453N, 13502585, 13586975, 13588312, 13597235, 201203202820, 208-242, 208-242A, 208-242B, 208-242C, 213-8379, 220921160357, 22962097, 400-40127, 430130133005, 431112093118, 90-22-5635, AVA0148, FG15S019, FG15S084, FG15S097, FG15S100, FGN15S097\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\u003e2017 Chevrolet Impala (3.6L V6 LFX)\u003c\/li\u003e\n  \u003cli\u003e2018 Chevrolet Impala (3.6L V6 LFX)\u003c\/li\u003e\n  \u003cli\u003e2019 Chevrolet Impala (3.6L V6 LFX)\u003c\/li\u003e\n  \u003cli\u003e2020 Chevrolet Impala (3.6L V6 LFX)\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 Epsilon II Impala?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2017-2020 Chevrolet Impala equipped with the \u003cstrong\u003eLFX\u003c\/strong\u003e 3.6L V6 engine. \u003cstrong\u003eThis unit does not fit models equipped with the 2.5L 4-cylinder engine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to reset the battery monitoring sensor after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, performing a battery relearn or driving through standard drive cycles ensures the body control module accurately tracks the output curve of the new alternator.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle continuous highway cruising and intense urban stop-and-go driving, this charging unit restores factory-grade electrical stability so your Impala remains dependable under heavy operating loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67915529289976,"sku":"DS-EHFC9ALPO","price":116.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-chevrolet-impala-2017-2020-3-6l-1.jpg?v=1793465800","url":"https:\/\/performancechiptuning.com\/products\/high-output-alternator-for-chevrolet-impala-2017-2020-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
