Mounted low on the engine block, original units endure severe exhaust heat radiation and road contamination, causing high internal resistance, sluggish cranking, and repeated contact chatter. Over time, worn solenoid contacts cause intermittent no-start conditions, single-click failures, or drive gear milling against the flexplate ring gear.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement unit incorporates a \u003cstrong\u003ePMGR (Permanent Magnet Gear Reduction)\u003c\/strong\u003e architecture delivering 1.4 kW of starting power at 12 volts while drawing significantly lower amperage than legacy direct-drive units. Engineered with dense copper windings, high-durability internal brushes, and a heavy-duty contact solenoid, it provides stable cranking torque under high thermal load. A surface-hardened 10-tooth pinion drive gear ensures precise, positive meshing with the flexplate ring gear, resisting tooth wear and gear runout under severe duty cycles.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 PMGR 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: 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;\"\u003e1997-2010 Ford Explorer\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;\"\u003e4.0L Cologne V6 \/ UN105, U152, U251\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;\"\u003e210 hp \/ 254 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;\"\u003e3273, 4R3T-11000-AA, SFD0039, F89U-11000-BA, 6L2T-11000-AA\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\u003e1997-2010 Ford Explorer 4.0L V6 (Automatic Transmission Only)\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 UN105, U152, and U251 Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1997-2010 Ford Explorer equipped with the \u003cstrong\u003e4.0L Cologne V6\u003c\/strong\u003e engine. \u003cstrong\u003eFits automatic transmission models only; manual transmission applications are excluded.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to modify any wiring or connectors during installation?\u003c\/h4\u003e\n\u003cp\u003eNo, this unit retains the factory bolt pattern and terminal configuration for plug-and-play installation to your original wiring harness.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe utility demands, this starter delivers dependable high-torque engagement in freezing conditions, extreme heat, and rugged trail use.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898417479928,"sku":"DS-EOJZJ0I2S","price":71.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/starter-for-ford-explorer-1997-2010-4-0l-1.jpg?v=1793320595","url":"https:\/\/performancechiptuning.com\/de\/products\/starter-for-ford-explorer-1997-2010-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
