Product Overview

The A2TX3081 is a Mazda OE-spec replacement alternator delivering 12V 150A output with a 6-rib (6PK) pulley, engineered for the Mazda 3 (BM, BN), Mazda 6 (GJ, GL) and Mazda CX-5 (KE, GH, KF) models powered by the 2.2-litre SKYACTIV-D diesel engine family (SHY1, SHY4, SHY6, SHY8). This brand-new aftermarket unit matches the original charging-system specification of these Japanese diesel platforms.

Fitted with internal regulator design, this alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 150-amp rating is factory-correct for the electrical load of these vehicles, supporting the diesel glow-plug system, climate control, heated and powered accessories, infotainment and the i-ELOOP energy-recovery charging strategy on fitted models.

Key physical specs: net weight 5.85 kg, gross weight 6.2 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.

The Mazda SKYACTIV-D 2.2D Platform and 150A Charging System

The Mazda 3, Mazda 6 and Mazda CX-5 share the 2.2-litre SKYACTIV-D diesel engine family (SHY1, SHY4, SHY6, SHY8 engine codes) across the BM / BN, GJ / GL and KE / GH / KF chassis generations, and share the same charging-system architecture with a 6-rib belt driven alternator and internal regulator.

This unit is specified as 12V 150A, 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.

Technical Specifications

Engine Compatibility

This alternator fits the following Mazda models with the 2.2D SKYACTIV-D engine. 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.

Multiple Mazda 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, A2TX3081 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 150A. 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 Mazda model, engine code (SHY1 / SHY4 / SHY6 / SHY8) 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 5.85 kg net; significant weight difference indicates wrong assembly.

Application Scenarios

• Independent repair shops and Mazda specialists servicing 3, 6 and CX-5 diesel models across Europe, Asia-Pacific, North America, Latin-America, the Middle East and Africa.

• Parts counters and jobbers stocking Japanese diesel charging-system components.

• Vehicle owners restoring and maintaining original-spec Mazda SKYACTIV-D models.

• Used-car export traders supplying pre-owned Mazda diesel vehicles to global secondary markets.

• Owners with standard electrical loads who require a factory-spec charging system.

FAQ

Q: Which Mazda models does this alternator fit?
A: It fits Mazda 3 (BM, BN), Mazda 6 (GJ, GL) and Mazda CX-5 (KE, GH, KF) models with the 2.2-litre SKYACTIV-D diesel engine (SHY1, SHY4, SHY6, SHY8). Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.

Q: My old alternator shows OE number SH0118300 or PY1C-18-300, will A2TX3081 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 2.2 diesel only?
A: Yes. This unit is specified for the 2.2-litre SKYACTIV-D diesel engine family as listed in the Engine Compatibility table. It is not for petrol engine variants.

Q: What is the normal charging voltage after installation?
A: With the engine running, output voltage should read approximately 13.8V-14.5V. On models with the i-ELOOP system, the charging strategy is controlled by the vehicle energy management system.

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 Mazda SKYACTIV-D 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 Mazda 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.
