Jeep Wagoneer Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Jeep Wagoneer replacement engines. Whether you are managing Hurricane Twin-Turbo cooling issues in the modern WS chassis or addressing oil consumption in classic SJ-era V8s, we provide direct OEM-spec solutions for the entire series.
Jeep Wagoneer Replacement Engines
The Jeep Wagoneer series spans two critical eras: the classic SJ platform (1963–1991) and the contemporary WS generation (2022–present). Across the modern WS lineup, shared architecture means technical bulletins like TSB 18-043-22 regarding powertrain control modules affect the entire series. The classic SJ generations, primarily powered by AMC-derived 5.9L V8s, suffer from common rear main seal failures and timing gear wear due to shared casting designs. In the modern era, the introduction of the Hurricane 3.0L Twin-Turbo across all Wagoneer variants has highlighted series-wide vulnerabilities in the intercooler circuit and PCV valve assembly. Because both the standard and long-wheelbase "L" models share identical engine mounts and cooling systems, these mechanical issues remain consistent across all luxury trims within the generation.
Jeep Wagoneer Models & Engines Codes
The Wagoneer series utilizes a range of heavy-duty powerplants designed for high-torque performance across all generations:
- Stellantis Hurricane (SST): 3.0L Twin-Turbo I6 (WS, 2022–present) – Shared intercooler efficiency issues in all variants.
- HEMI Eagle: 5.7L V8 with eTorque (WS, 2022–present) – Hemi-tick and exhaust manifold bolt failures across the series.
- AMC 360: 5.9L V8 (SJ, 1970–1991) – Shared oiling system weaknesses and timing chain slack.
- AMC 258: 4.2L I6 (SJ, 1963–1986) – Manifold gasket leaks common across all early utility trims.
Modern WS engines are integrated with the Torqueflite 8HP75 transmission, requiring series-specific ECU synchronization during any engine replacement process.
Buy Used and Second-Hand Jeep Wagoneer Engines
For Wagoneer owners, used engines carry risks due to shared generational flaws. Reconditioned units are highly recommended for the following reasons:
- Hurricane Series: Remanufactured units include updated cooling gaskets (Part 68444391AA) to prevent the heat soak issues found in used stock.
- HEMI Variants: Rebuilt 5.7L engines feature reinforced exhaust manifold studs to address the series-wide snapping problem.
- SJ Classic Series: Second-hand AMC blocks often require full line-boring to correct decades of shared vibration wear.
Our suppliers ensure that every replacement unit for the Wagoneer series addresses these known architecture-wide vulnerabilities before delivery.

Expert Tips for Choosing the Right Engine for Your Jeep Wagoneer
♻️ Jeep Wagoneer Engine Types Explained
- Reconditioned: Best for the 5.7L Hemi V8, addressing MDS lifter failure with updated parts.
- Used Low-Mileage: A viable option for the 6.4L Hemi V8 from US-market donor vehicles.
- Remanufactured OEM: Ideal for the new 3.0L Hurricane I6, replacing complex twin-turbo systems.
- For early 5.2L V8s (1990s), a used engine is often the only cost-effective solution.
£ Jeep Wagoneer Replacement Engine Cost in the UK
- Used 5.7L Hemi V8 for models 2011-2021: £4,500 - £7,000.
- Reconditioned 6.4L Hemi V8 with new cam/lifters: £9,000 - £14,000.
- Complete 3.0L Hurricane I6 long block assembly: £16,000+.
- Sourcing from US breakers can save 30-50% vs. UK-supplied units.
🔍 Finding the Right Jeep Wagoneer Engine
- Locate the engine RPO code on the vehicle's build sheet or VIN decoder.
- Key codes: 'ESG' for 5.7L Hemi, 'ERB' for 6.4L Hemi, 'E58' for 3.0L Hurricane.
- Pre-1991 models use the AMC 360 or 401 V8, requiring specific carbureted units.
- Ensure the engine includes the correct ECU and wiring harness for your model year.
⛽ Jeep Wagoneer Petrol vs Diesel Engines
- The Wagoneer was offered with a 6.2L Detroit Diesel V8 up to 1993.
- Historic diesel models are non-ULEZ compliant and parts are scarce.
- All modern Wagoneers (2011+) are petrol-only (5.7L, 6.4L, 3.0L Hurricane).
- For UK driving, the 3.0L Hurricane I6 offers the best efficiency for its size.
🔒 Quality Assurance & Warranty
- For 5.7L Hemi, verify installation of revised MDS lifters (part 53010487AC).
- Check that remanufactured 6.4L Hemis include the updated cam phaser (68302247AA).
- A 24-month / 24,000-mile warranty is standard for quality UK rebuilders.
- Ensure dyno sheets verifying torque output (~400 lb-ft for 5.7L) are provided.
🛒 Compare & Save on Jeep Wagoneer Engines
- Import a used US-spec Hemi engine and have it reconditioned locally.
- Avoid suppliers who haven't addressed the Hemi's known valve seat recession issue.
- For classic models, consider a modern Hemi crate engine swap for reliability.
- We provide direct access to US salvage auctions specialising in Jeep trucks.
⚙️ Jeep Wagoneer Engine Works: How Experts Rebuild Engines
When your engine fails, Jeep Wagoneer 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. Hemi-Specific Disassembly & Failure Analysis
The engine is stripped with focus on Hemi failure points: MDS lifters, camshaft lobes, and exhaust valve seats. Oil galley plugs are removed to check for sludge common in older Wagoneers used for towing.
2. Block & Cylinder Head Reconditioning
The hemispherical combustion chambers are meticulously cleaned and inspected for cracks. Blocks are hot-tanked and the valley under the intake manifold is examined for coolant leaks, a known issue on the 5.7L.
3. Critical Hemi Component Replacement
All MDS components (lifters, valley tray, solenoids) are replaced with the latest Mopar non-MDS delete kit or updated parts. The camshaft is always replaced with a nitrided version (P5153844) to prevent repeat failure.
4. Reassembly with Updated TSB Parts
Engine is rebuilt using torque specs for the heavy-duty truck application. Updated head bolts and intake manifold gaskets per TSB 09-001-20 are installed. The oil pump is replaced with a high-volume unit for better lubrication.
5. Fuel System & Management Integration
For later model fuel-injected engines, all injectors are cleaned and flow-tested. The ECU is flashed with the latest calibration to prevent the 'Hemi tick'. For carbureted classics, the carb is fully rebuilt.
6. Chassis Dyno Tuning & Break-In
The rebuilt engine is run on a dyno with a break-in cycle specific to flat-tappet (classic) or roller cam (modern) Hemis. Power and vacuum are verified to ensure it meets the Wagoneer's heavy towing demands.
