Chevy 2.4L L4 Remanufactured Engine – 2011-2015

Chevy 2.4L L4 Remanufactured Engine – Professional Overview

The Chevy 2.4L L4 Remanufactured Engine – 2011-2015 is a replacement 2.4L inline-four engine configured for specific Buick, Chevrolet, and GMC California-emissions applications.

This engine configuration incorporates Dual Variable Valve Timing (Dual VVT) and Gasoline Direct Injection (GDI). The supplied information identifies the engine assembly codes as NU6 and LEA.

A particularly important characteristic of this engine is its California-emissions configuration. The supplied description specifies California emissions ONLY and identifies the presence of smog holes between the exhaust manifold.

The cylinder head is identified by Head Cast #12608282, with the supplied identification markings I: 207 – E: 896.

Because this engine has a specific emissions configuration and application range, fitment should be verified carefully before ordering. The engine assembly code, head casting, smog-hole configuration, emissions specification, and vehicle application should all correspond with the original engine.

Compatibility and Applications

This 2.4L L4 remanufactured engine is specified for California-emissions applications using the GM Code NU6 configuration with smog holes in the cylinder head.

The supplied vehicle applications include the following:

• 2011–2015 Buick LaCrosse C, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2012–2016 Chevrolet Equinox K, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2011–2016 GMC Terrain C, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2011–2012 Buick Regal R, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2012–2015 Buick Regal K, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2015 Buick Regal C, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2014 Chevrolet Impala R, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head
• 2013–2014 Chevrolet Malibu R, 2.4L, California Emissions Only, GM Code NU6, with smog holes in head

The supplied application list extends beyond the 2011–2015 model-year range shown in the product title, so buyers should use the specific vehicle application and fitment information rather than relying only on the product title.

The product description recommends verifying fitment through the Vehicle Fitment information and the applicable casting numbers under Additional Information.

Remanufacturing Process and Quality

The Chevy 2.4L L4 Remanufactured Engine undergoes a comprehensive remanufacturing process.

The process begins with complete disassembly. Cast-iron components are hot tanked, while aluminum components are thermally cleaned.

Following cleaning, components are inspected. Magnaflux testing uses magnetic particles to inspect applicable metal components for microscopic cracks and fissures. Components are also visually inspected.

The deck surfaces are CNC machined during the machining stage.

Specified new components are installed during rebuilding. These include bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, and galley plugs.

Depending on the applicable engine configuration, the timing system receives either a new timing chain with new tensioners or a new timing belt with a new tensioner.

Where an engine uses a timing-driven water pump, the supplied process states that a new water pump is installed.

After reassembly, each engine undergoes SIM testing. The cooling and oil systems are fully pressurized, while the crank is spun at high RPM to verify compression and build quality.

The supplied description states that every engine is fully remanufactured to meet or exceed OEM specifications.

Why This 2.4L Remanufactured Engine Stands Out

This Chevy 2.4L L4 Remanufactured Engine has a clearly defined configuration that helps buyers identify the correct application.

Its California-emissions-only specification, NU6 engine code, Dual VVT, GDI, and specified cylinder-head configuration are important distinguishing characteristics.

The remanufacturing process also provides multiple quality-control stages. The engine is completely disassembled, deeply cleaned, inspected, machined, rebuilt with specified new components, and tested after assembly.

The use of Magnaflux inspection provides a dedicated inspection process for applicable metal components, while CNC machining is used on the deck surfaces.

The final SIM testing process includes pressurization of the cooling and oil systems and high-RPM crank testing to verify compression and build quality.

These details are particularly relevant for buyers who need to match a replacement engine to a specific emissions configuration rather than simply selecting a 2.4L engine based on displacement alone.

Who This Product Is Best For

This 2.4L L4 replacement engine is intended for customers replacing the engine in a compatible Buick, Chevrolet, or GMC application listed for this configuration.

It can be relevant to vehicle owners, automotive repair shops, professional technicians, engine replacement specialists, and commercial automotive buyers.

The product is especially relevant when the original engine corresponds with the supplied GM Code NU6, California emissions configuration, and smog-hole cylinder-head configuration.

Buyers should verify their exact vehicle application and engine identification before ordering. The supplied information identifies NU6 and LEA as engine assembly codes, while the listed vehicle applications specifically reference GM Code NU6 with smog holes in the head.

Technical Specifications

Ordering and Warranty Information

Before ordering the Chevy 2.4L L4 Remanufactured Engine, buyers should carefully verify the exact application and emissions configuration.

This engine is specifically identified as California Emissions Only. The supplied vehicle applications also reference GM Code NU6 with smog holes in the head, making the cylinder-head configuration an important fitment consideration.

Buyers should compare their original engine against the supplied NU6/LEA assembly codes, Head Cast #12608282, and the specified I: 207 – E: 896 identification.

The supplied installation warning is particularly important. It states that these engines can experience failures associated with clogged catalytic converters, which can cause overheating and damage to the head gasket and other components.

According to the supplied information, failures involving overheating are not covered under the warranty. The product description therefore advises that the mechanic properly diagnose the cause of the original engine failure. If overheating was the cause, the catalytic converter should be checked and replaced as appropriate.

The supplied warranty information states that each engine comes with up to 7 years and 1 million miles of warranty, with Pure Care™ no-fault protection available as an upgrade.

Specific warranty terms and coverage should be confirmed before purchase.
