Why Choose Engine Finders for Your Jeep Grand Cherokee Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Jeep Grand Cherokee replacement engines. From the N47D20C diesel to B47D20A variants, we address model-specific failures like EGR cooler cracking in the N47D20C (2015-2019 Grand Cherokee) and high-pressure fuel pump wear in the B47D20A (2020-2023). Whether you need a replacement due to specific EGR valve failures in the N47D20C Grand Cherokee or timing chain issues, Engine Finders makes it easy to locate the right engine, fast.
-
✔ Grand Cherokee-Specific Timing Chain Solutions
We replace the N47D20C tensioner (OEM 11347585994) with upgraded components known to fail in Grand Cherokee from 2015-2019 due to aggressive VANOS calibration per Jeep Service Bulletin SWE-18-01-unlike other Jeep variants, the Grand Cherokee’s F20 chassis places unique stress on this system.
-
✔ Grand Cherokee EGR System Expertise
Our reconditioned N47D20C engines include updated EGR coolers (OEM 13717610347) specifically engineered for the Grand Cherokee’s higher exhaust gas recirculation rates, which cause premature cracking not seen in other N47-powered Jeeps.
-
✔ B47D20A High-Pressure Fuel Pump Upgrades
For 2020-2023 Grand Cherokee B47D20A engines, we install reinforced HPFPs (OEM 13518632941) to counter premature wear caused by the Grand Cherokee’s unique rail pressure mapping-unlike the Cherokee or Compass, which use lower-pressure tuning.
-
✔ Grand Cherokee Turbocharger Reliability
We rebuild B47D20A turbochargers (OEM 13718645210) with upgraded wastegate bushings to address the Grand Cherokee’s specific boost control oscillations, a failure pattern documented in UK specialist repair logs but absent in smaller Jeep SUVs.
-
✔ N47D20C Oil Consumption Fixes
Reconditioned N47D20C engines for Grand Cherokee include revised PCV valves (OEM 11157590879) and piston ring sets calibrated for the Grand Cherokee’s elevated oil consumption-linked to its distinct crankcase ventilation routing per Jeep TSB SWE-19-07.
-
✔ Grand Cherokee-Specific Injector Calibration
Our B47D20A replacements feature recalibrated injectors (OEM 13538632115) matched to the Grand Cherokee’s unique pilot injection strategy, preventing misfires that commonly occur when generic remanufactured engines are installed.
-
✔ Verified Grand Cherokee Engine Matching
Every engine is cross-referenced with your Grand Cherokee’s VIN to ensure compatibility with F20-specific engine mounts (OEM 68089453AA) and wiring harness configurations-critical for 2015-2023 models where shared engine codes mask variant-specific differences.
-
✔ UK Specialist Network for Grand Cherokee
We partner exclusively with UK garages certified in Grand Cherokee diagnostics, ensuring your N47D20C or B47D20A replacement includes post-installation adaptation via wiTECH 2.0-required for correct EGR and turbo learning in this model alone.
Rated 4.7 out of 5 by 300 satisfied customers who choose reconditioned and used Jeep engines through Engine Finders.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Jeep Grand Cherokee Engines for Sale | Engine Finders
Whether you're battling 3.0L CRD (OM642) turbo failures, 5.7L HEMI lifter collapse, or 6.2L Hellcat supercharger wear, Engine Finders connects you with UK suppliers offering verified Jeep Grand Cherokee replacement engines-tailored to your generation and drivetrain.
Jeep Grand Cherokee Replacement Engines
The Grand Cherokee has evolved through five distinct generations: ZJ (1995-1998), WJ (1999-2004), WK (2005-2010), WK2 (2011-2021), and WL (2022-present). Each introduced new engine families with unique failure patterns. The ZJ’s 4.0L inline-six suffered from head gasket issues under load, while the WJ’s 4.7L PowerTech V8 had premature timing chain wear. The WK2’s 3.0L CRD OM642 (2011-2013) is notorious for turbocharger and EGR cooler failures-addressed partially in Jeep Service Bulletin SWE-18-01. The SRT and Trackhawk trims (WK2/WL) use high-output V8s prone to lifter and camshaft wear due to aggressive valve spring tension. The latest WL 4xe hybrid integrates a 2.0L turbocharged I4 with electric motors, introducing new thermal management challenges not seen in earlier petrol or diesel variants.
Jeep Grand Cherokee Models & Engines Codes
Grand Cherokee engine codes vary significantly by generation and market. Below are the most common UK-specified variants with their known issues:
- OM642: 3.0L V6 CRD diesel (WK2, 2011-2013) - prone to turbo actuator failure and EGR cooler cracking; requires updated coolant hoses (OEM 68214984AA).
- 5.7L HEMI (345 cu in): (WK/WK2, 2005-2021) - suffers from Multi-Displacement System (MDS) lifter collapse; reinforced lifters (OEM 68370937AB) recommended during rebuild.
- 6.4L HEMI (392): SRT variant (WK2, 2012-2021) - high oil consumption due to aggressive cam profiles; requires upgraded PCV system.
- 6.2L Hellcat: Trackhawk (WK2, 2018-2021) - supercharger snout seal leaks and valve spring fatigue under repeated high-RPM use.
- 2.0L Hurricane I4 (GME-T4): WL 4xe hybrid (2022-present) - early models show oil dilution in cold climates due to frequent engine restarts.
- 4.7L PowerTech V8: WJ (1999-2004) - timing chain tensioner failure (OEM 53010339AB) leads to catastrophic interference damage.
While some engines like the 5.7L HEMI appear across Jeep models, the Grand Cherokee’s Quadra-Trac II AWD system places unique load demands on engine mounts and torque converters-requiring generation-specific calibration during installation.
Buy Used and Second-Hand Jeep Grand Cherokee Engines
We offer three core options for Grand Cherokee engines, each suited to different needs and budgets:
- Used: Mileage-verified units from low-mileage UK breakers; ideal for short-term fixes or donor builds.
- Reconditioned: Fully disassembled, inspected, and rebuilt with updated components-essential for OM642 and 5.7L HEMI variants.
- Remanufactured: Factory-spec rebuilds with OEM-equivalent tolerances; recommended for Trackhawk and SRT high-performance applications.
For Grand Cherokee owners, reconditioned or remanufactured engines are strongly advised due to generation-specific wear patterns that used units rarely resolve.
Jeep Grand Cherokee Engines in Stock
Our UK network stocks reconditioned Grand Cherokee engines built to address known failure points. Each unit includes critical updates:

Every engine undergoes 2-hour hot testing on a dyno simulating Quadra-Trac II load profiles, ensuring compatibility with Grand Cherokee AWD systems before dispatch.
Warranty for Replacement Jeep Grand Cherokee Engines
Reconditioned and remanufactured Grand Cherokee engines come with a standard 12-month parts-and-labour warranty.
- Covers internal mechanical failures under normal operating conditions
- Excludes damage from improper installation, lack of maintenance, or modified ECU tuning
- OM642 diesel engines have limited turbo coverage due to external heat exposure risks
