HAYIAUTO 11453N 150A Alternator for Chevy Equinox, Impala, GMC Terrain & Buick LaCrosse: Fitment, Specs and Replacement Guide

2010–2012 Chevy Equinox 3.0L Alternator

The Chevrolet Equinox is one of the primary applications for this replacement.

The 2010–2012 Equinox was available with a 3.0-liter V6 engine, and the HAYIAUTO 11453N is advertised for compatible models.

If your Equinox repeatedly needs jump-starting, displays a charging warning, or experiences electrical problems while driving, the alternator may be failing.

However, the 11453N is not the same replacement as the 11459N alternator advertised for select 2.4L four-cylinder Equinox models.

Buying warning: Verify your engine displacement before ordering. A 3.0L V6 alternator should not be assumed to fit a 2.4L four-cylinder Equinox.

2010–2012 GMC Terrain 3.0L Alternator

The GMC Terrain shares much of its mechanical architecture with the Chevrolet Equinox.

The HAYIAUTO 11453N is advertised for compatible 2010–2012 Terrain models equipped with the 3.0L V6.

Because the Terrain was also offered with a four-cylinder engine, matching the engine and original alternator part number is essential.

2012–2016 Chevrolet Impala 3.6L Alternator

The 2012–2016 Chevrolet Impala 3.6L V6 is another advertised application.

The 150A alternator supplies electrical power to the engine-management system, lighting, climate control, and other accessories.

However, model-year overlap and changing vehicle generations mean buyers should verify the exact original equipment configuration.

2014–2016 Chevrolet Impala Limited Alternator

The Chevrolet Impala Limited continued using the previous-generation Impala platform for fleet-oriented applications.

The HAYIAUTO 11453N is advertised for 2014–2016 Impala Limited models equipped with the 3.6L V6.

Confirm the original alternator number rather than relying solely on the Impala nameplate.

2010–2016 Buick LaCrosse Alternator

The manufacturer advertises compatibility with:

• 2010 Buick LaCrosse 3.0L V6
• 2010–2016 Buick LaCrosse 3.6L V6

Because the LaCrosse was available with different powertrains and charging-system configurations, VIN-specific verification is important.

2010–2012 Cadillac SRX Alternator

The Cadillac SRX requires special attention.

The product is advertised for 2010–2011 SRX 3.0L V6 models and certain 2012 SRX 3.6L V6 models.

Important production restriction: The supplied listing specifies 2012 SRX 3.6L applications built through January 16, 2012.

If your SRX was built after that date, do not assume this alternator fits.

2012 Chevrolet Captiva Sport Alternator

The 2012 Chevrolet Captiva Sport 3.0L V6 is also included in the advertised compatibility list.

Verify the original alternator reference number and electrical connector before purchasing.

HAYIAUTO 11453N OEM Cross-Reference Numbers

Matching the original alternator’s identification number is one of the most useful ways to verify compatibility.

The manufacturer advertises the following interchange references:

These numbers come from the supplied product listing.

They should not be interpreted as independent confirmation that every reference is interchangeable across every listed vehicle.

Before purchasing, compare the original alternator’s part number, amperage, mounting configuration, electrical connector, and pulley.

Why a 150-Amp Alternator Matters on GM V6 Engines

The alternator supplies electricity to the vehicle while the engine runs and replenishes the battery after starting.

On GM vehicles equipped with 3.0L and 3.6L V6 engines, electrical power supports numerous systems, including:

• Engine control module
• Fuel injection and ignition systems
• Electric cooling fans
• Headlights and exterior lighting
• Climate-control blower
• Rear-window defroster
• Audio and infotainment equipment
• Safety and stability-control electronics
• Battery charging

The HAYIAUTO 11453N’s advertised 150-amp rating makes it a potential replacement for compatible factory charging systems.

However, installing a 150-amp alternator does not automatically improve electrical performance if the vehicle was not designed for that particular unit.

The correct mounting arrangement, regulator behavior, pulley, and electrical connector are just as important as the amperage rating.

Six Signs Your Chevy Equinox or Impala Alternator Is Failing

Alternator failure can develop gradually, sometimes producing warning signs before the charging system stops working.

1. Battery Warning Light

An illuminated battery warning light while driving may indicate a charging-system problem.

The warning can be triggered by insufficient alternator output, damaged wiring, belt problems, or charging-control faults.

For additional troubleshooting, read our guide to why your battery warning light is on.

2. Battery Keeps Going Dead

If your Equinox, Terrain, or Impala repeatedly needs jump-starting, the alternator may not be replenishing the battery correctly.

However, a deteriorating battery, parasitic electrical draw, or corroded terminals can cause the same symptoms.

Before purchasing replacement parts, follow our guide to testing alternator output with a multimeter.

3. Headlights Flicker or Dim

Headlights that change brightness unexpectedly may indicate unstable charging voltage.

The symptoms can become more noticeable when several electrical accessories are operating simultaneously.

4. Whining or Grinding Noise

Worn alternator bearings can produce whining, grinding, or rattling sounds that change with engine speed.

However, a damaged belt tensioner, idler pulley, or other accessory-drive component may create similar noises.

5. Electrical Accessories Malfunction

Low or unstable voltage can contribute to intermittent warning lights, accessory problems, and unusual electronic behavior.

These symptoms should be investigated before replacing the alternator.

6. Engine Stalls or Won’t Restart

If the alternator stops charging, the vehicle may continue operating temporarily using stored battery power.

Once voltage drops too low, critical engine electronics may stop functioning.

Driving with a confirmed charging-system failure is not recommended.

How to Test Your GM V6 Alternator Before Replacing It

One of the most common DIY repair mistakes is replacing an alternator without confirming that it has failed.

A digital multimeter can help identify obvious charging-system problems.

Step 1: Check Battery Voltage

With the engine off and the battery rested, measure voltage across the battery terminals.

A fully charged conventional 12V lead-acid battery typically reads approximately 12.6 volts.

Step 2: Start the Engine

Measure voltage again with the engine running.

Many conventional charging systems operate around 13.5–14.8 volts during active charging.

However, GM electronically controlled charging systems may intentionally vary alternator output according to battery condition and electrical demand.

A single low reading does not automatically establish alternator failure.

Step 3: Apply Electrical Load

Turn on the headlights, climate-control blower, and rear-window defroster.

Observe how the charging system responds.

Step 4: Inspect the Charging Circuit

Check the battery terminals, alternator output cable, grounds, drive belt, and related electrical connections.

Our automotive voltage-drop testing guide explains how excessive electrical resistance can interfere with charging performance.

Safety warning: Never disconnect the battery while the engine is running to test the alternator. Voltage spikes can damage sensitive vehicle electronics.

HAYIAUTO 11453N Alternator Construction and Features
