Remanufactured GM 5.3L Vortec V8 with VVT and AFM for 2010-2014 engines (LMG, LC9). Zero miles, built to order, free shipping, no core charge.

Build time: usually 5-7 days, plus shipping (varies by engine; contact us for current availability).

Fitment

2014: the 2014 Tahoe, Yukon, Suburban and Yukon XL are still the previous body style with these engines (covered here). The new 2014 Silverado / Sierra 1500 uses the direct-injection L83: see our GM 5.3L EcoTec3 direct-injection (L83 / L84 / L82) listing.

Confirm by VIN: 2010-2011 Chevrolet Tahoe / GMC Yukon with the LC9 (VIN 3) is listed by only one of our sources. If your 2010-2014 5.3L shows VIN J, contact us before ordering. Send us your VIN.

Confirm your engine

• VIN: the 8th digit of your VIN is the engine code (0 = LMG, 3 or 7 = LC9).
• RPO code: look for the engine RPO code on the Service Parts Identification (SPID) label, usually in the glove box.
• Gen III vs Gen IV: 1999-2007 Gen III 5.3L engines use a 24x crank reluctor with the cam sensor at the rear of the block; 2007-2014 Gen IV truck engines use a 58x crank reluctor with the cam sensor in the front cover.
• VVT: 2010-2014 VVT engines have a cam phaser on the front of the camshaft (behind the timing cover) and a phaser control solenoid on the front cover.
• AFM: AFM engines have the lifter oil manifold (solenoid assembly) under the intake manifold in place of a plain valley cover.

Casting numbers

• Block (LMG, cast iron, Gen IV): 12576177, 12576178 or 12589779
• Block (LC9, aluminum, Gen IV): 12571048, 12601900, 12569513 or 12568573
• Cylinder heads: 799 or 243 (cathedral port; last three digits of the casting number)

Where to find casting numbers: the block casting number is on the driver side rear of the block, just above the bellhousing flange and below the driver-side cylinder head (hard to read in the vehicle; a mirror and flashlight help). On the cylinder heads, the last three digits of the casting number are cast into the head near the corner/end, just below the valve cover.

Check the 8th digit of your VIN (0 = LMG, 3 or 7 = LC9) or the RPO code on the SPID label, and choose your engine code from the dropdown. Then choose Factory AFM or AFM Delete. Send us your VIN to confirm fitment.

Notes

• Cylinder deactivation: these engines came with Active Fuel Management (AFM). Choose Factory AFM (built with AFM, as original) or AFM Delete (tune required) (+$500) in the Cylinder Deactivation option above.
• The AFM valley cover (lifter oil manifold with the AFM solenoids) is an electronic part and is not included. We recommend replacing your original with a new one for a Factory AFM build. For an AFM Delete build, use the AFM delete valley plate below instead.
• AFM delete: The AFM delete option requires a tune after installation. The tune is the customer's responsibility.

Break-in

The first 1,000 miles are the break-in period. Use conventional oil only, change the oil and filter at 500 miles, vary your RPM, and avoid towing, heavy loads and long idling. Check your oil level regularly, since some oil burn-off is normal until the rings seat. Following the break-in procedure is required to keep your warranty.

Warranty, core and performance parts

Warranty: 1-year unlimited-mile warranty on the engine only; labor is not covered. Optional 3-year extended warranty available for $1,500 (includes labor coverage at $50/hr). See our Warranty & Refund Policy. Add the 3-year extended warranty to your order.

Core charge: none. All engines are built to order.

Performance parts: we do not blueprint engines. We can install custom or performance parts you supply (you pay for the parts and shipping them to us; no extra installation charge), but this waives the 1-year warranty.
