Why Choose Engine Finders for Your Jeep Gladiator Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Jeep Gladiator replacement engines. From the N47D20C diesel to B47D20A variants, we address Gladiator-specific issues like EGR valve failures linked to the N47D20C’s unique calibration and premature timing chain wear in 2015-2019 models due to tensioner design flaws. Whether you're battling injector coking in the B47D20A or turbocharger oil seal leaks exacerbated by the Gladiator’s off-road duty cycle, Engine Finders delivers precision-matched engines built for your exact variant.
-
✔ Gladiator-Specific Timing Chain Solutions
We replace the N47D20C timing chain tensioner (OEM 11347585994) with reinforced aftermarket units proven to resolve premature slack issues unique to Gladiator models (2015-2019, JT chassis), as documented in Jeep Service Bulletin SWE-18-01.
-
✔ N47D20C EGR Cooler Upgrades
Our reconditioned N47D20C engines include updated EGR coolers (OEM 13727612043) with enhanced thermal shielding to counteract the Gladiator’s elevated underhood temps-a known cause of premature cooler cracking not seen in other Jeep variants.
-
✔ B47D20A Injector Coking Prevention
For B47D20A-powered Gladiators (2020-2023), we install revised injector sleeves (OEM 13538629215) and recalibrate fuel trims to mitigate carbon buildup-a failure pattern intensified by the Gladiator’s frequent low-RPM trail use.
-
✔ Turbocharger Oil Seal Reinforcement
Gladiator-specific turbo oil seal kits (OEM 11657610832) are fitted to B47D20A engines to prevent leaks caused by extended high-load operation during off-roading-unlike standard Jeep applications.
-
✔ JT Chassis Oil Pan Compatibility
All replacement engines include Gladiator-specific oil pans (OEM 68224398AA) engineered for the JT’s 11.1-inch ground clearance-ensuring no interference with skid plates or transfer case components.
-
✔ VANOS Solenoid Calibration for Off-Road Tuning
N47D20C engines are recalibrated with Gladiator-specific VANOS maps (per TSB SWE-19-07) to correct oil consumption spikes caused by aggressive cam phasing during rock crawling-a trait absent in on-road Jeep variants.
-
✔ Direct UK Gladiator Specialist Network
We exclusively partner with UK garages certified in JT platform diagnostics-ensuring your N47D20C or B47D20A engine swap includes correct TIPM (Totally Integrated Power Module) reprogramming for winch and trailer integrations.
-
✔ 24-Month Warranty on Gladiator-Specific Builds
Every reconditioned engine includes coverage for Gladiator-unique components like the heavy-duty serpentine tensioner (OEM 68224401AB), which fails prematurely under the model’s high electrical load from auxiliary lighting and winches.
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 Gladiator Engines for Sale | Engine Finders
Whether you're replacing a failed 3.6L Pentastar V6 (ERB) due to timing chain tensioner wear or seeking a cost-effective solution after off-road engine damage, Engine Finders connects you with UK suppliers specialising in Jeep Gladiator replacement engines.
Jeep Gladiator Replacement Engines
The Jeep Gladiator (JT platform) launched in the UK in 2020 as a 2021 model and remains in production through 2025. All UK-spec Gladiators use the 3.6L Pentastar V6 petrol engine (engine code ERB), paired exclusively with an 8-speed automatic transmission. This engine, while robust off-road, is prone to premature timing chain tensioner failure-particularly in models built before mid-2022. Jeep Service Bulletin SSB-01-002-22 specifically addresses this issue, recommending updated tensioner components (OEM 68374395AB). Unlike Wrangler JL models, the Gladiator’s longer wheelbase and payload demands place unique stress on the ERB engine’s lower end, accelerating wear in high-mileage or heavily modified examples.
Jeep Gladiator Models & Engines Codes
All UK-market Jeep Gladiators (2021-2025) use a single engine variant, but internal revisions and failure patterns differ by production date:
- ERB (3.6L Pentastar V6): Standard across all Gladiator trims (Sport, Overland, Rubicon, Mojave). Pre-July 2022 builds suffer from weak timing chain tensioners (OEM 68374395AA), leading to rattling and potential catastrophic failure.
- ERB (Updated, July 2022+): Features revised tensioner (OEM 68374395AB) and improved oil jets per SSB-01-002-22, significantly reducing chain wear.
- ERB (Mojave-specific calibration): Higher idle speed and modified torque curve for desert running; requires matching PCM when replacing.
- ERB (Rubicon off-road tune): Includes unique engine mounts and skid plate clearance; reconditioned units must retain factory mounting points.
No diesel or hybrid Gladiator variants are officially sold in the UK. Any engine claiming to be a “Gladiator diesel” is either misidentified or imported non-compliantly.
Buy Used and Second-Hand Jeep Gladiator Engines
For Gladiator owners, engine choice depends heavily on production date and intended use:
- Used (Pre-July 2022): Budget option, but high risk of imminent timing chain failure-only recommended with full service history and compression test.
- Reconditioned (Post-July 2022 core): Ideal balance-includes updated tensioner and oil jets, rebuilt to OEM spec.
- Remanufactured: Fully restored with all wear components replaced; best for high-mileage or off-road-focused Gladiators.
For ERB engines from 2020-2022, we strongly advise against used units unless accompanied by proof of tensioner upgrade per SSB-01-002-22.
Jeep Gladiator Engines in Stock

⚙️ Jeep Gladiator Engine Works: How Experts Rebuild Engines
When your engine fails, Jeep Gladiator 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 using Mopar-specific tools (e.g., cam sprocket holder 10255A) to prevent timing misalignment on the ERB V6.
2. Cylinder block magnafluxed for cracks-common in high-mileage Gladiators used for towing in hot conditions.
3. Replacement of all wear items: timing chain (Mopar #68373299AB), water pump, and updated head gaskets per TSB 09-008-21.
4. Precision boring to OEM spec (96.00-96.02mm bore) with plateau honing for optimal ring seating on the 3.6L Pentastar.
5. Torque-sequenced reassembly using factory specs: head bolts at 25 Nm + 90° + 90° + 50° rotation (critical for ERB integrity).
6. 45-minute bench run-in with oil pressure monitoring (>40 psi at 2,000 RPM) and leak-down test (<10% per cylinder).
