Product Overview
The A3TX1691 is a Ford OE-spec replacement alternator delivering 12V 175A output with a 6-rib (6PK) pulley, engineered for Ford Edge, Explorer, Flex and Lincoln MKT models powered by the 3.5-litre and 3.7-litre V6 engine family (T35PDED, T35PDTD, T37PDED). This brand-new aftermarket unit matches the original charging-system specification of these North American platforms.
Fitted with internal regulator design, this alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 175-amp rating is factory-correct for the high electrical load of these vehicles, supporting climate control, heated and powered accessories, infotainment and the battery management charging strategy.
Key physical specs: net weight 6.35 kg, gross weight 6.65 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The Ford Edge / Explorer / Flex Platform and 175A Charging System
Ford Edge, Explorer, Flex and Lincoln MKT models with the 3.5-litre and 3.7-litre V6 engine family carry a very high factory electrical load from climate control, heated and powered accessories, infotainment and battery management, which is why the charging system is rated at 175A.
This unit is specified as 12V 175A, matching the factory charging-system specification of these platforms. The 6-rib pulley matches the original accessory-belt layout. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility
This alternator fits the following Ford and Lincoln models. Do not rely solely on the model name for fitment validation; always verify engine code, production year, old-part OE number, pulley rib-count and amp label on your original alternator.
| Model | Chassis | Engine Code | Displacement | Years |
|---|---|---|---|---|
| Ford Edge (incl. AWD) | U387 | T37PDED | 3726cc | 2010-2013 |
| Ford Explorer (incl. 4WD, EcoBoost) | U2, U_, U5_ | 99X, 998, T35PDTD | 3496-4000cc | 1994-2015 |
| Ford Flex (incl. AWD) | - | T35PDED, T35PDTD | 3496cc | 2008-2012 |
| Lincoln MKT 3.5 AWD | - | T35PDTD | 3496cc | 2009-2012 |
Multiple Ford, Lincoln and supplier OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, A3TX1691 serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the amperage label on your old alternator: confirm it is rated for 175A. Different amp ratings are not interchangeable.
2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.
3. Confirm the exact Ford / Lincoln model, engine code and production year of your vehicle.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 6.35 kg net; significant weight difference indicates wrong assembly.

FAQ
Q: Which Ford / Lincoln models does this alternator fit?
A: It fits Ford Edge, Explorer, Flex and Lincoln MKT models with the 3.5-litre and 3.7-litre V6 engine family. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.
Q: Does this fit Ford Taurus or Lincoln MKS?
A: The page title lists Taurus and MKS, but the fitment table covers Edge, Explorer, Flex and MKT. Confirm the OE number and mounting layout with your old unit before ordering.
Q: My old alternator shows OE number DG1Z-10346-F or 8A4T10300AB, will A3TX1691 work?
A: Yes. These numbers belong to the same alternator family, differing only by production revision and market specification. It serves as a direct replacement.
Q: Is this alternator for the 3.5 EcoBoost engine?
A: Yes. It covers both the naturally-aspirated 3.5 / 3.7 V6 (T35PDED, T37PDED) and the 3.5 EcoBoost (T35PDTD) as listed in the Engine Compatibility table.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.
In Practice
For technicians working on Ford Edge, Explorer, Flex and Lincoln MKT vehicles: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.
Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Ford workshop-manual specifications.
Inexperienced home mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle-system components.
