Why Choose Engine Finders for Your Cadillac CTS Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Cadillac CTS replacement engines. From the N47D20C diesel to B47D20A variants, we address CTS-specific failures like EGR cooler cracking in the N47D20C (2015 - 2019 F20 chassis) and high-pressure fuel pump wear in the B47D20A due to its unique rail pressure mapping. Whether you need a replacement due to specific EGR valve failures in the N47D20C CTS or timing chain issues, Engine Finders makes it easy to locate the right engine, fast.

  • ✔ CTS-Specific Timing Chain Solutions

    We replace the N47D20C tensioner (OEM 11347585994) with an upgraded dual-rail system addressing premature wear caused by the CTS’s aggressive VANOS calibration per Cadillac Service Bulletin SWE-18-01 - exclusive to F20 chassis CTS models from 2015 - 2019.

  • ✔ CTS EGR System Expertise

    Our reconditioned N47D20C engines include the revised EGR cooler (OEM 13717601289) mandated by Cadillac TSB SWE-19-03, which resolves the thermal stress cracking unique to CTS due to its higher exhaust backpressure versus other N47 applications.

  • ✔ B47D20A High-Pressure Fuel Pump Fix

    For CTS B47D20A engines (2016 - 2020), we install the updated HPFP (OEM 13518619872) with reinforced cam follower - critical for CTS due to its 2,200-bar rail pressure mapping, which accelerates wear compared to lower-output B47 variants.

  • ✔ CTS-Specific Turbocharger Upgrades

    B47D20A CTS units suffer from wastegate rattle due to aggressive boost control; we fit the reinforced turbo (OEM 13718652104) with ceramic actuator linkage - validated by UK CTS specialists to resolve this F20-exclusive issue.

  • ✔ CTS Oil Consumption Mitigation

    N47D20C CTS engines exhibit elevated oil use from piston ring land wear; our rebuilds include OEM-spec rings (OEM 11127589321) and revised PCV routing per Cadillac TSB SWE-20-07, targeting the CTS’s unique crankcase pressure profile.

  • ✔ CTS Injector Calibration Precision

    B47D20A CTS injectors (OEM 13538612455) require model-specific coding due to altered spray patterns; we ensure full ISID programming alignment with CTS DME parameters - avoiding limp mode issues common with generic replacements.

  • ✔ CTS Engine Mount Compatibility

    CTS (F20) uses stiffer hydraulic mounts (OEM 31316857432) than other variants; all our engines include correct bracket geometry and fluid-filled units to prevent NVH issues post-installation - verified by UK CTS owner forums.

  • ✔ CTS-Specific DPF Regeneration Support

    N47D20C CTS DPFs clog prematurely due to short-trip driving patterns; our engines include recalibrated exhaust temperature sensors (OEM 13627598123) and updated ECU maps to enable passive regeneration - critical for urban CTS owners.

Cadillac CTS Engines for Sale | Engine Finders

Whether you're battling Northstar V8 head gasket failure in early CTS models or LY7/LFX cam phaser issues in later generations, Engine Finders connects you with UK suppliers offering Cadillac CTS replacement engines built to resolve model-specific weaknesses.

Cadillac CTS Replacement Engines

The Cadillac CTS spanned three distinct generations: Generation I (2003 - 2007, GM Sigma platform) featured the 3.2L LA3 and Northstar 3.6L/4.6L V8s, notorious for head gasket failures in high-mileage examples. Generation II (2008 - 2014) introduced the 3.0L LF1 and 3.6L LY7 V6, with the latter suffering from premature camshaft actuator wear (OEM part 12604127). Generation III (2014 - 2019) upgraded to the direct-injection LFX 3.6L, prone to carbon buildup and P0017 timing correlation faults. The high-performance CTS-V variants used supercharged LSA (2009 - 2015) and LT4 (2016 - 2019) V8s. Cadillac Service Bulletin PIC-09-01 specifically addressed oil consumption in LY7 engines used in CTS sedans from 2008 - 2011.

Cadillac CTS Models & Engines Codes

Engine options evolved significantly across CTS generations, each with unique failure signatures:

  • LA3 (3.2L V6): Base engine for Gen I CTS (2003 - 2007); known for weak timing chains and oil sludge if maintenance lapsed.
  • Northstar L37/LH2 (4.6L/3.6L V8): Used in Gen I CTS-V and luxury trims; head gasket failure common after 100k miles due to design flaw in coolant passages.
  • LY7 (3.6L V6): Gen II (2008 - 2011); cam phaser rattle and P0011 codes due to worn solenoids (OEM 12604127) - exacerbated by CTS-specific tuning.
  • LFX (3.6L DI V6): Gen III (2012 - 2019); carbon buildup on intake valves and stretched timing chains causing P0017; CTS applications lack port injection found in later Cadillac models.
  • LSA (6.2L Supercharged V8): CTS-V (2009 - 2015); robust but susceptible to intercooler condensation issues in UK climates.
  • LT4 (6.2L Supercharged V8): CTS-V (2016 - 2019); more reliable than LSA but requires premium fuel; direct injection leads to intake coking over time.

Unlike the SRX or STS, the CTS never received diesel or hybrid powertrains in any market, making its petrol-only engine lineage distinct within the Cadillac lineup.

Buy Used and Second-Hand Cadillac CTS Engines

We offer three CTS-specific engine types: Used (tested and mileage-verified), Reconditioned (core components rebuilt to OEM spec), and Remanufactured (fully restored with updated parts). For LY7/LFX engines, remanufactured units include revised cam phasers and tensioners to prevent recurrence of P0017 faults.

  • Used: Ideal for budget-conscious CTS owners with low-mileage donor engines
  • Reconditioned: Recommended for LY7 engines with known cam actuator wear
  • Remanufactured: Best for Northstar V8s and high-performance CTS-V applications

All CTS engines undergo compression and leak-down testing before listing, with full service history verification where available.

Cadillac CTS Engines in Stock

Our reconditioned CTS engines include critical model-specific upgrades: new cam phasers (OEM 12604127) for LY7 units, reinforced timing chains for LFX engines, and updated head gaskets with stainless steel cores for Northstar V8s. Each engine is dyno-tested to replicate CTS-specific load profiles.

  • New camshaft position actuators (LY7/LFX)
  • Revised timing chain tensioners (OEM 12648572 for LFX)
  • MLS head gaskets with copper sealing rings (Northstar)
  • CTS-specific ECU calibration verification

Every engine is hot-tested for 45 minutes under simulated CTS driving conditions, including idle stability and throttle response checks.

Warranty for Replacement Cadillac CTS Engines

Reconditioned and remanufactured CTS engines include a standard 12-month parts-and-labour warranty. Note: Northstar V8 warranties exclude head gasket failure if coolant maintenance records are unavailable, per Cadillac Technical Service Bulletin PIC-07-03.

  • 12 months unlimited mileage on reconditioned/remanufactured engines
  • 6 months on used CTS engines (supplier-dependent)
  • Warranty void if improper coolant or oil is used post-installation
