Does the 105 Amp Alternator fit 2004-2008 Acura TSX models?

Yes, the 105 Amp Alternator for Acura CSX CR-V TSX is compatible with 2004-2008 Acura TSX 2.4L models. This unit is designed to replace the original factory component to provide the electrical power needed to run the vehicle’s systems and charge the battery.

The 105 Amp Alternator serves as the engine-driven generator that converts mechanical energy into the electricity powering your car’s lights, electronics, and motor. Our comparison of the Acura-compatible options identified this unit as a match because it supports the 2.4L engine configuration used in the TSX during those years. Because the TSX shares several electrical architecture points with the Accord and CR-V, this part carries multiple reference numbers, including 13980N and 31100-RAA-A05. For an alternator buyer, confirming these specific fitment details is critical because even a small difference in the mounting bracket orientation or pulley groove geometry can cause the serpentine belt to slip or prevent the unit from seating against the engine block.

What to Check Before Buying the 105 Amp Alternator

Before purchasing, confirm these technical details to ensure the part matches your specific vehicle configuration.

• Verify the pulley groove geometry matches your original factory belt to prevent squealing or slippage.
• Confirm the electrical connector pin configuration is identical to your OEM plug to avoid a no-start condition.
• Check that the mounting bracket orientation matches your specific TSX engine layout rather than a mirrored layout used on other models.
• Ensure the internal voltage regulator is compatible with your vehicle’s specific ECU logic to avoid overcharge codes.
• Confirm if the unit includes the necessary mounting hardware or if you need to source your own bolts and brackets.
