This is a used part. This 2.0L 4-cylinder turbo engine (237 HP) was tested and runs well. It is for vehicles with an automatic transmission and rear-wheel drive (RWD). This assembly does not include the turbocharger. You may need to switch your original induction, exhaust, electrical, and fuel system components onto this engine to work with your vehicle.

This engine fits Rear-Wheel Drive (RWD) models only. It does not fit All-Wheel Drive (AWD) vehicles. Please verify your vehicle has the 2.0L turbocharged engine (8th VIN digit 'K') before ordering. The turbocharger assembly is not included.

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 that the 8th digit of your VIN is 'K'.
  • Confirm your vehicle is Rear-Wheel Drive (RWD).
  • Locate the barcode label on the front timing cover of your current engine to verify it matches the LSY family layout.
🔎 Where to look: The 8th digit of the VIN must be 'K'. The engine broadcast code is located on a label near the top of the engine front cover, just below the oil fill cap.

What the install really takes — plan and budget with confidence:

12 to 20 hoursshop labor$1,500 to $3,000+typical shop bill, on top of the partExpertDIY difficulty

Special tools this job needs:

  • Camshaft Alignment/Timing Tool Kit (EN-52461 / EN-52476 / EN-52462)
  • Flywheel Holding Tool (EN-52461-2)
  • GM-compliant scan tool (Tech 2 or MDI2)
  • Torque-to-yield bolt sockets
  • Torque wrench
  • Vacuum coolant refiller tool
🔌 Wiring harness: We highly recommend transferring your original engine wiring harness to this replacement engine to prevent any minor pinout or connector differences.

Budget for these consumables at install:

  • Engine Oil: 5.3 quarts (5.0 Liters) of synthetic 0W-20 oil meeting GM dexos1 Gen 3 or dexosD specifications
  • Oil Filter: New OEM-spec spin-on oil filter
  • Coolant: GM-approved Dex-Cool (50/50 pre-mixed)
  • Spark Plugs: New pre-gapped OEM-spec iridium spark plugs
  • Intake manifold gasket set
  • Exhaust manifold gasket
  • Thermostat/Coolant outlet gaskets
  • Turbocharger mounting gasket and oil/coolant feed line O-rings
  • Crankshaft harmonic balancer bolt (Torque-to-Yield, single-use)
  • Flywheel/Flexplate bolts (Torque-to-Yield, single-use)
  • Camshaft actuator bolts (if removed)
  • Accessory serpentine belt

What your vehicle’s computers will need after the swap:

⚠️ Requiredprogramming / calibration⚠️ Yesdealer tool needed✅ NoECU/PCM re-marriage

What’s involved: Crankshaft Position (CKP) Variation Learn, Camshaft Position Sensor Learn, and Immobilizer/Anti-Theft Relearn

Requires a GM-specific scan tool (such as GM MDI with GDS2, Tech 2, or MDI2) to perform the Crankshaft Position Variation Learn and sync the engine to the vehicle's immobilizer/BCM.

Pro tips for a smooth first start-up — hand them to whoever does the install:

  • Mandatory Vacuum Coolant Filling: Active Thermal Management system with rotary Coolant Control Valve traps air. You must use a vacuum coolant refiller tool to prevent localized hot spots and cylinder head warping.
  • Fragile Sliding Cam System (SCS) Actuators: Plastic actuators on top of the valve cover crack easily when maneuvering the engine into the tight Cadillac engine bay.
  • Torque-to-Yield (TTY) Bolts: Critical fasteners like the harmonic balancer bolt, cylinder head bolts, and main bearing caps are single-use and must be replaced.
  • Meticulous Grounding: Pay close attention to all engine and chassis ground strap locations to prevent bizarre electrical issues.
  • Turbocharger Transfer: Inspect the old turbo for shaft play or oil leaks, and clean all oil/coolant lines before connecting them.

Easy to get right once you know them:

  • Ordering for an AWD Vehicle: Purchasing this RWD engine for an AWD Cadillac CT4 or CT5. AWD models use a completely different oil pan with an axle pass-through.
  • Ignoring the 'LESS TURBO' Note: Assuming a complete engine includes the turbocharger, leading to unexpected costs and delays.
  • Skipping the Crankshaft Position Relearn: Skipping the mandatory CKP relearn, which results in a flashing Check Engine Light, disabled misfire detection, and limp mode.
  • Manual Coolant 'Burping': Attempting to bleed the cooling system without a vacuum filling tool, causing rapid overheating.
  • Reusing Old Consumables: Reusing old gaskets, seals, or TTY bolts on a direct-injection, turbocharged engine.

Researched from factory recalls, TSBs and OEM service data (reference unit 300-10472-5213209). Unit-specific details — mileage, condition, warranty, freight — are covered in the checkout interview.

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.
