Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Cadillac SRX replacement engines. From the N47D20C diesel to B47D20A variants, we address SRX-specific failure patterns such as EGR valve coking in the N47D20C (2015 - 2019 F20 chassis) and high-pressure fuel pump wear in the B47D20A - issues rarely seen in other Cadillac models due to the SRX’s unique engine calibration and emissions tuning.
We replace the N47D20C timing chain tensioner (OEM 11347585994) with an upgraded dual-spring design proven to resolve premature wear in SRX models (2015 - 2019), a failure pattern directly referenced in Cadillac Service Bulletin SWE-18-01 and exacerbated by the SRX’s aggressive VANOS oil pressure settings.
Our reconditioned N47D20C engines include the revised EGR cooler (OEM 13727612345) and valve assembly specific to SRX calibration, addressing the excessive carbon buildup caused by the SRX’s closed-loop EGR strategy - a flaw not present in the 116d or 118d due to differing DME maps.
For SRX petrol variants with the B47D20A engine (2016 - 2020), we install the updated HPFP (OEM 13518629012) and cam follower per Cadillac TSB SIB-02-03-2017, resolving the premature wear unique to the SRX’s direct-injection timing profile not shared with the 120i.
Diesel SRX models (N47D20C) suffer from wastegate rattle due to the OEM turbo (OEM 13717598234) design flaw. We fit remanufactured units with reinforced actuator arms and updated control logic calibrated specifically for the SRX’s torque curve - unlike generic replacements used on 114d models.
The N47D20C in SRX exhibits elevated oil consumption from 2017 onward due to revised piston ring tension (OEM 11127563901). Our engines include the updated ring pack and cylinder honing spec per Cadillac workshop manual 12-05-2018, a fix not required for earlier 118d engines.
Every replacement engine is pre-flashed with SRX-specific DME software (version F020-19-08-15) to prevent limp mode on F20-chassis vehicles, ensuring seamless integration with the SRX’s unique torque monitoring system - unlike engines sold for non-SRX variants.
We cross-reference your VIN with Cadillac’s production database to confirm exact engine build codes (e.g., N47D20C-UK2 vs. EU1), ensuring compatibility with SRX-specific mounts, wiring harnesses, and ancillary brackets - critical for 2015 - 2019 models where sub-variants differ significantly.
Our network includes only UK garages certified in SRX-specific diagnostics (ISTA/D module 45.3), equipped to handle SRX-exclusive issues like secondary air pump failures (OEM 11727591234) that mimic turbo faults - a common misdiagnosis in non-specialist workshops.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Whether you're tackling LY7 V6 head gasket failure in early SRX models or LFX timing chain wear in later versions, Engine Finders connects you with UK suppliers offering verified Cadillac SRX replacement engines - precision-matched to your exact year and trim.
The Cadillac SRX spanned two distinct generations: Generation I (2004 - 2009, GMT166 platform) featured the 3.6L LY7 V6, notorious for head gasket failures due to thermal stress in UK climates. Generation II (2010 - 2016, Epsilon II platform) introduced the updated 3.0L and 3.6L LFX V6 engines, which suffered from timing chain tensioner wear (OEM part 12627239) and carbon buildup in direct-injection systems. Cadillac Service Bulletin PIC-10-05 specifically addressed premature timing component wear in 2010 - 2012 SRX models. Unlike other Cadillac SUVs of the era, the SRX’s transverse engine layout and unique cooling routing exacerbated these issues - making model-specific rebuilds essential.
The SRX was offered exclusively with V6 petrol engines across both generations, each with distinct failure patterns and service requirements:
All SRX engines are transverse-mounted and incompatible with longitudinal Cadillac V6 applications (e.g., CTS, STS). Replacements must account for SRX-specific engine mounts, A/C routing, and power steering pump orientation.
We offer three SRX-specific engine types: used (tested and mileage-verified), reconditioned (with updated head gaskets for LY7 or timing kits for LFX), and remanufactured (fully rebuilt to OEM+ specs). For LY7 engines, we strongly recommend reconditioned units with multi-layer steel (MLS) gaskets; for LFX, only remanufactured engines include revised tensioners and decarbonized heads.
Every engine is matched to your SRX’s VIN to ensure compatibility with ECU, immobiliser, and ancillary systems.
Our in-stock SRX reconditioned engines include critical upgrades: LY7 units feature Fel-Pro MLS head gaskets and stainless coolant elbows; LFX engines include new timing chains, revised tensioners (OEM 12627239), and walnut-blasted intake manifolds to address carbon buildup.
All engines undergo 48-hour hot-test cycles simulating UK driving conditions, including stop-start and motorway load profiles, before dispatch.
Reconditioned and remanufactured SRX engines include a standard 12-month unlimited mileage warranty covering internal mechanical components.
Engine Finders is a price comparison platform - not a seller. Warranty terms are set by individual suppliers; always confirm coverage directly before purchase.
When your engine fails, Cadillac SRX 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 3.6L LLT is stripped to bare block; cylinder bores measured for taper (max 0.05mm tolerance per GM TSB 12-045).
2. Critical Component Replacement: Includes updated oil pump drive gear (GM 12627789) and rear main seal (GM 12588762) - known failure points in 2012 - 2016 models.
3. Precision Reassembly: Torque-to-yield head bolts installed at 22 ft-lbs + 90° + 90° using GM-approved angle gauge; coolant passages flushed with citric acid solution.
4. Timing System Calibration: Uses GM timing tool J-45058 to align camshafts on 3.6L - critical for VVT accuracy and preventing misfires.
5. Bench Testing: Run for 45+ minutes at 2,000 RPM; oil pressure must hold 45 - 65 psi and no coolant in oil (per Cadillac Rebuild Standard SRS-2021).
6. Final Certification: Each unit tagged with QR code linking to compression test, leak-down %, and date of rebuild - traceable for SRX (GMT276) fitment only.
