Over repeated heat cycles, OEM solenoid contacts pit, internal brush assemblies wear thin, and armature insulation degrades. This leads to common failure symptoms: intermittent no-starts, high electrical resistance causing rapid solenoid clicking, labored cranking, or starter free-spin when the drive gear fails to engage the flexplate ring gear.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct replacement for OEM part numbers \u003cstrong\u003e12588493\u003c\/strong\u003e, \u003cstrong\u003e12598756\u003c\/strong\u003e, and \u003cstrong\u003e12598757\u003c\/strong\u003e, this heavy-duty starter utilizes a 1.4 kW permanent magnet gear reduction (PMGR) architecture. The PMGR design yields substantially higher breakaway torque while pulling fewer cold cranking amps from the battery. Constructed with high-conductivity copper windings, a heat-treated 12-tooth pinion gear, and an upgraded solenoid housing, it resists thermal degradation and contact oxidation. Every unit is dyno-tested to verify rotational speed and pull-in amperage before leaving the facility.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Starter Motor\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;\"\u003e2007-2016 GMC Acadia\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 High Feature V6 (LY7 \/ LLT) \/ Lambda\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;\"\u003e275-288 hp \/ 251-270 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;\"\u003e17986, 17997, 12588493, 12598756, 12598757\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\u003e2007-2016 GMC Acadia 3.6L V6 (SL, SLE, SLT, Denali)\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 Lambda Acadia?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2016 GMC Acadia equipped with the 3.6L \u003cstrong\u003eLY7\u003c\/strong\u003e or \u003cstrong\u003eLLT\u003c\/strong\u003e V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhat should I check before installing this replacement starter?\u003c\/h4\u003e\n\u003cp\u003eAlways verify the 12V battery holds a full charge and all cable terminals are clean and torqued, as excessive voltage drop mimics a defective starter motor.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to endure the daily demands of towing, cargo hauling, and extreme temperature swings, this heavy-duty starter ensures the full-size \u003cstrong\u003eLambda\u003c\/strong\u003e chassis cranks reliably without electrical hesitation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898408403192,"sku":"DS-E6L3A05KT","price":69.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/starter-for-gmc-acadia-2007-2016-3-6l-1.jpg?v=1793320304","url":"https:\/\/performancechiptuning.com\/de\/products\/starter-for-gmc-acadia-2007-2016-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
