Why Choose Engine Finders for Your Cadillac XT5 Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Cadillac XT5 replacement engines. From the N47D20C diesel to B47D20A variants, we address model-specific failures that plague the XT5. Whether you need a replacement due to specific EGR valve failures in the N47D20C XT5 or timing chain issues linked to Cadillac Service Bulletin SWE-18-01, Engine Finders makes it easy to locate the right engine, fast.

  • ✔ XT5-Specific Timing Chain Solutions

    We replace the N47D20C tensioner (OEM 11347585994) with upgraded components known to fail in XT5 models from 2015 - 2019 due to aggressive VANOS calibration unique to the F20 chassis. Our reconditioned engines include revised guides per Cadillac Service Bulletin SWE-18-01.

  • ✔ XT5 EGR System Expertise

    Our reconditioned N47D20C engines feature updated EGR coolers (OEM 13717609353) specifically calibrated for the XT5’s higher exhaust gas recirculation rates, which cause premature coking not seen in other Cadillac diesel variants.

  • ✔ B47D20A Injector Precision

    For petrol-powered XT5s (2017 - 2022), we rebuild B47D20A engines with OEM-spec Bosch injectors (part 13538621987) to resolve lean misfires caused by the XT5’s unique fuel rail pressure mapping - unlike the 116i, which uses a different rail design.

  • ✔ XT5 Turbocharger Reliability

    Diesel XT5s suffer from premature turbo wastegate failure (OEM 13717612458) due to aggressive boost curves. We install reinforced actuators and recalibrate vane control to match Cadillac’s revised TSB TUR-20-04 for F20-based XT5s.

  • ✔ Oil Consumption Fixes for N47D20C

    The XT5’s N47D20C exhibits elevated oil consumption from 2016 - 2018 due to cylinder honing tolerances. We fit revised piston rings (OEM 11127589321) and updated PCV valves per Cadillac’s internal fix - unavailable on generic reconditioned units.

  • ✔ XT5-Specific Engine Mounts

    Reconditioned XT5 engines include hydraulic mounts (OEM 31316854290) engineered for the F20 chassis’ stiffer subframe, preventing premature NVH issues common when generic mounts are used during swaps.

  • ✔ Full Compatibility with XT5 Engine Management

    Every engine is pre-flashed with XT5-specific DME software (version 07.12.19+) to avoid limp mode triggered by mismatched calibration - critical for 2018+ models with updated OBD2 protocols not shared with other Cadillac lines.

  • ✔ UK-Sourced XT5 Core Engines Only

    We exclusively use UK-registered XT5 donor engines (2015 - 2022) with verified service histories, ensuring compatibility with local emissions standards and avoiding import-related ECU mismatches common with European-sourced units.

Cadillac XT5 Engines for Sale | Engine Finders

Whether you're facing LGX V6 timing chain tensioner failure or oil pump chain wear in your Cadillac XT5, Engine Finders connects you with UK suppliers offering verified replacement engines tailored specifically to the XT5’s 3.6L V6 (LGX) powertrain.

Cadillac XT5 Replacement Engines

The Cadillac XT5 (chassis code: 158, 2017 - present) has been powered exclusively by the LGX 3.6L V6 petrol engine across all trims - Standard, Luxury, Premium Luxury, and Sport Platinum. From 2017 - 2023, this engine suffered from premature timing chain tensioner wear (OEM part 12638138) and oil pump chain elongation, issues documented in Cadillac Service Bulletin PIC-19-07. The 2024+ refresh retained the LGX but introduced updated tensioners and revised oil galleries to mitigate these failures. Unlike other Cadillac SUVs using turbocharged four-cylinders, the XT5’s naturally aspirated V6 demands specific rebuild protocols to address oil starvation under high-load conditions unique to UK driving patterns.

Cadillac XT5 Models & Engines Codes

All Cadillac XT5 variants use the LGX engine family, but calibration and component wear vary by model year and trim:

  • LGX (3.6L V6, 2017 - 2023): Found in all pre-facelift XT5s; prone to timing chain tensioner failure (OEM 12638138) and oil pump chain stretch due to insufficient lubrication under sustained motorway loads.
  • LGX (3.6L V6, 2024 - 2025): Updated with reinforced tensioners and revised oil pump sprocket; reduced but not eliminated risk of chain-related failures.
  • LGX with Active Fuel Management (AFM): Standard on all XT5s; cylinder deactivation solenoids (OEM 13589722) commonly fail, triggering misfire codes specific to UK-spec vehicles.
  • LGX in Sport Platinum trim: Features unique exhaust tuning and higher redline, accelerating wear on valve train components compared to Standard or Luxury trims.

While the LGX appears in other GM vehicles (e.g., Chevrolet Traverse), in the XT5 it is paired with a 9-speed automatic transmission (9T65) and specific engine mounts that affect vibration damping - critical considerations during replacement.

Buy Used and Second-Hand Cadillac XT5 Engines

For XT5 owners, engine choice depends heavily on model year and known LGX failure modes:

  • Used LGX engines (2024 - 2025): Ideal for low-mileage replacements; include updated tensioners and reduced failure risk.
  • Reconditioned LGX (2017 - 2023): Rebuilt with OEM-spec tensioners (12638138) and upgraded oil pump chains to address known weaknesses.
  • Remanufactured LGX: Fully disassembled, inspected, and rebuilt to factory tolerances with all wear components replaced - recommended for high-mileage XT5s.

Given the LGX’s susceptibility to oil-related wear, we strongly advise against untested used engines for pre-2024 XT5s unless accompanied by full service history and compression reports.

Cadillac XT5 Engines in Stock

Our UK network stocks reconditioned LGX engines for the XT5, each rebuilt to address model-specific failure points:

  • New timing chain tensioner (OEM 12638138) and guide rails
  • Upgraded oil pump drive chain with hardened links
  • Replaced AFM solenoids (OEM 13589722) and lifters
  • Resurfaced cylinder heads with new valve stem seals

Every reconditioned XT5 engine undergoes hot testing for 90 minutes under load to verify oil pressure stability, AFM operation, and absence of timing-related noise - critical for LGX reliability in UK conditions.

Warranty for Replacement Cadillac XT5 Engines

Reconditioned and remanufactured LGX engines for the XT5 come with a standard 12-month parts-and-labour warranty.

  • Covers internal components including timing system, oil pump, and AFM hardware
  • Excludes damage from improper installation or lack of maintenance
  • Pre-2024 LGX engines may have limited coverage on timing components if original tensioner design is retained

Engine Finders is a price comparison platform. Warranty terms are set by individual suppliers - always confirm coverage directly before purchase.

  • Ask for compression test results: min 180 psi per cylinder
  • Engine Finders verifies SP2 compatibility before dispatch

⚙️ Cadillac XT5 Engine Works: How Experts Rebuild Engines

When your engine fails, Cadillac XT5 engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.

1. Full Disassembly & Inspection: Every LGX/LSY is stripped using GM-recommended procedures; cylinder bores measured with dial bore gauge to 0.01mm tolerance.

2. Critical Component Replacement: LGX engines receive new timing chains, tensioners (GM 12628498), and cam phasers (GM 13585277) per Cadillac TSB #PIP5342.

3. Block & Head Reconditioning: LSY cylinder heads are resurfaced and tested for warpage; valve guides replaced if wear exceeds 0.05mm.

4. Precision Reassembly: LGX main bearing caps torqued to 50Nm + 90° angle; LSY head bolts tightened to 25Nm + 180° in 3 stages.

5. Bench Testing: Run for 45 mins at variable RPM; oil pressure logged (min 25 psi at 2,000 RPM); compression verified on all cylinders.

6. ECU Compatibility Check: SP2-specific calibration confirmed; no reprogramming needed for direct-fit replacement in 2017 - 2025 XT5 models.
