GM REGAL 2011 Adaptation Accessories Electronic Fan Selection Guide

1. Original parts replacement plan

It is recommended to lock the original specification electronic fan part number (such as the universal ACDelco series) through the vehicle VIN code to ensure compatibility with the cooling system control logic.

Third party brand parts must be clearly labeled as applicable to the 2011 Buick Regal, and priority should be given to choosing cooling system suppliers such as Aisin who have the same quality as the original factory.

2. Verification of key parameters

Voltage matching: The Regal electronic fan is powered by 12V DC, and the risk of confusion with 24V commercial vehicle accessories needs to be ruled out.

Power requirement: The mainstream accessory power range is 80W-120W (such as the 12 inch universal type), and low-power models may result in insufficient heat dissipation.

Interface compatibility: Verify that the pin definition of the motor plug matches the original vehicle harness to avoid ECU errors caused by modification.

Precautions for replacing electronic fans

Installation specifications

When disassembling the water tank frame, it is necessary to release the refrigerant pressure synchronously (if the electronic fan is integrated with the condenser) to avoid refrigerant leakage.

After installing the new fan, it is necessary to perform ECU adaptive learning and clear historical fault codes.

Performance verification

Turn on the AC switch of the air conditioner and confirm that the electronic fan is synchronously activated;

Heat up the car until the water temperature is above 90 ° C and observe whether the low-speed/high-speed gear switching is smooth.
