Why Buy a 2012 Chevy Engine from Auto Power Source

Every listing on this page is a unit we physically hold, counted live. The family table below sums to exactly 79 — the same number in the headline — because we never publish a figure higher than the stock behind it. If a 2012 engine family shows one unit, there is one unit.

2012 is a year where the badge on the fender tells you almost nothing. A 6.2L could be a Corvette and Camaro SS LS3, a Camaro automatic L99 with Active Fuel Management, a supercharged ZL1 LSA, or a Silverado 1500 L9H truck engine — four different castings, four different parts lists. A 6.0L could be the L96 gas V8, the LC8 CNG/LPG bi-fuel, the LZ1 two-mode hybrid, or the Australian-built L77 in a Caprice PPV. We title every unit by its RPO code so you are matching hardware, not displacement.

ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before a 2012 Chevy engine is approved for shipment. You see multi-angle photographs of the actual unit before any payment is taken, the freight is free on a heavy-duty pallet anywhere in the continental U.S., and you have 30 days from delivery to return for any reason with no restocking fee and no return freight charge.

Your 2012 Chevy Engine Options: Compared

Most 2012 Chevy owners face four real choices when the engine fails:

← Swipe sideways to see all columns →
Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High — tested Included VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same engineering as new, fraction of the cost.

2012 Chevy Engine Buying Guide

5 things to verify before buying a used 2012 Chevy engine:

  1. Work from the RPO option code, not the displacement. GM identifies 2012 hardware by a three-character option code on the service parts identification label, not by a VIN letter alone. LMG and LC9 are both 5.3L V8s with different Active Fuel Management and flex-fuel content; LUJ and LUV are both 1.4L turbos but sit in different cars. Match the code.
  2. Four 6.2L V8s and four 6.0L V8s share this model year. The 6.2L exists as LS3 (manual Corvette and Camaro SS), L99 (automatic Camaro with AFM), LSA (supercharged ZL1) and L9H (Silverado 1500 truck). The 6.0L exists as L96 (gas), LC8 (CNG and LPG bi-fuel), LZ1 (two-mode hybrid) and L77 (Holden-built Caprice PPV). None of them interchange.
  3. Check the emissions option code on the four-cylinders and the 3.6L. The Equinox 2.4L LEA is listed three ways — Federal NT7, California NU5 and California NU6 — and the Impala 3.6L LFX and Malibu 2.4L LE5 split the same way. The calibration and hardware differ, so a Federal unit is not a drop-in for a California car.
  4. Confirm the fuel system and, on cutaways, the tank count. Express 2500 and 3500 vans run the 6.0L as either L96 gasoline or LC8 CNG/LPG bi-fuel, and the LPG cutaways split again into a three-tank system (UFM) and a four-tank system (UFP). There is also a 5.3L LFT LPG Silverado 1500 in stock. Regular van and cutaway listings are kept separate on purpose.
  5. Confirm the match with your own VIN before you order. Your VIN settles the engine code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.

Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.

Frequently Asked Questions

How many 2012 Chevy engines do you actually have in stock?
79 right now. That is the live active listing count for model year 2012, and the family table on this page sums to exactly 79. We never publish a number higher than what we hold.
What is the warranty on a 2012 Chevy engine?
Up to 3 years depending on the specific unit, plus 30 days from delivery to return for any reason with no restocking fee and no return freight charge.
What does ASE-tested mean?
ASE-certified technicians compression-test every cylinder and run a leak-down evaluation on each unit, then verify it for noise and smoke on a test stand, inspect it visually and photograph it from multiple angles before it is approved for shipment.
How do I tell an LS3 from an L99, an LSA or an L9H?
By the RPO option code on the service parts identification label, which is tied to your VIN. LS3 is the manual-transmission Corvette and Camaro SS engine, L99 is the automatic Camaro version with Active Fuel Management, LSA is the supercharged ZL1 engine, and L9H is the 6.2L truck engine in the Silverado 1500. Send us the VIN and we will read it for you.
Is the Sonic 1.4L the same engine as the Cruze 1.4L?
No. Both are 1.4L Ecotec turbos, but the Sonic uses RPO LUV and the Cruze uses RPO LUJ, and they are listed separately here. The 1.8L LUW is shared between the two cars, with manual and automatic applications listed apart.
How long until delivery?
Prep and ship time is 3 to 5 business days, then 2 to 3 business days in transit via freight carrier. Shipping is free to the continental U.S. on a heavy-duty pallet.
Why is a used OEM engine cheaper than a dealer-new one?
It is used OEM hardware from a low-mileage donor vehicle — the same Chevrolet engineering, at a fraction of dealer-new pricing, with no quality compromise in the casting or the internals.

Our 6-Step Inspection & Shipping Process

Every 2012 Chevy engine we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm engine/transmission code, emissions calibration, and drivetrain fit.
2. Tested & Verified
ASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: turbos, manifolds, valve covers, housings, accessories, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.

Our Photos-Before-Shipment Guarantee

Before any 2012 Chevy engine leaves our warehouse, we send you multi-angle photographs. You approve.
