Know This Engine Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this engine family:
A quick look at your own vehicle makes sure the right engine shows up:
- Verify the 8th digit of the VIN is A
- Confirm the vehicle is a 4x4 (Four-Wheel Drive) model
- Locate the Engine RPO Code LCV on the Service Parts Identification label
- Inspect the oil pan to verify it has the clearance notch and mounting bosses for the front axle tube
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- EN-48219 Fuel Injector Remover/Installer kit
- EN-43653 Flywheel Holding Tool
- Engine hoist
- Engine stand
- Torque wrench
Budget for these consumables at install:
- 5 quarts of Dexos1 Gen2 (or Gen3) approved full synthetic 5W-20 or 0W-20 oil
- New ACDelco PF64 oil filter (or equivalent)
- Fresh GM-approved Dex-Cool coolant (50/50 pre-mix)
- New intake manifold gaskets
- New exhaust manifold gasket
- New water pump gasket
- New OE-spec iridium spark plugs
- New high-pressure fuel injector Teflon seals
- New high-pressure fuel pump O-ring
- New thermostat
What your vehicle’s computers will need after the swap:
What’s involved: Crankshaft Position (CKP) Sensor Variation Relearn
sources differ: Arm 1 states a dealer scan tool is required (GM MDI with Techline Connect / GDS2), while Arm 2 states that many high-end professional scan tools can also initiate the CKP relearn procedure. A professional-grade scan tool is mandatory to prevent persistent P0300 codes or false misfire DTCs.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- 4x4 Oil Pan Alignment: The oil pan is uniquely notched to clear the front axle tube and differential assembly. Take extreme care when lowering the engine to ensure you do not crush or crack the aluminum oil pan.
- Torque-to-Yield (TTY) Bolts: The harmonic balancer bolt, cylinder head bolts, and flywheel/flex plate bolts are torque-to-yield (one-time use only) and must be replaced.
- Vacuum Pump & Camshaft Alignment: The mechanical vacuum pump is driven directly by a coupler on the rear of the exhaust camshaft. You must align the pump drive tab perfectly with the slot on the end of the camshaft to avoid snapping the camshaft.
- High-Pressure Fuel System Safety: Relieve fuel system pressure before disconnecting lines. Replace the high-pressure fuel crossover pipe and injector Teflon seals to prevent fuel leaks.
- Ground Straps: Ensure all engine and chassis ground straps are clean, secure, and reconnected to their original locations.
Easy to get right once you know them:
- Ordering for a 2WD (RWD) Truck: The 4x4 oil pan has specific clearance notches and mounting bosses for the front differential. If installed in a 2WD truck, the pan will not clear steering and suspension geometry unless swapped.
- Ordering for Transverse (FWD) Cars/SUVs: Do not buy this engine for a Chevy Malibu, Impala, Blazer, or Buick Envision due to completely different engine mount locations, accessory drive layouts, and wiring harnesses.
- Reusing the Old Oil Cooler After a Spun Bearing: Metal shaving debris trapped inside the oil cooler and lines will wash directly into the replacement engine and destroy the bearings, voiding the warranty.
- Skipping the Crankshaft Relearn: Assuming the engine is plug-and-play will result in a persistent check engine light and poor running conditions.
- Reusing Old Gaskets and Seals: Reusing compressed gaskets causes vacuum or exhaust leaks.
- Incorrect Fluid Usage: Failing to use GM DEX-COOL coolant and dexos1 Gen 2 specified oil can lead to cooling system damage and sludge buildup.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
