Jeep Grand Wagoneer Engines for Sale | Engine Finders

Whether battling Hurricane Twin-Turbo cooling issues across the latest WS generations or oil consumption in classic SJ V8 configurations, we provide direct OEM-spec solutions for the entire series.
Jeep Grand Wagoneer Replacement Engines
The Jeep Grand Wagoneer evolved through two distinct eras: the iconic SJ platform (1984–1991) and the modern WS luxury chassis (2022–present). Across the series, technical bulletins such as TSB 18-043-22 have addressed powertrain control modules and cooling efficiencies. The SJ generations, featuring AMC-derived 5.9L V8s, often face shared rear main seal leaks and timing gear wear. In contrast, modern WS variants (Series I, II, III) utilize high-output Hurricane 3.0L engines where intercooler heat soak and PCV valve failures represent common series-wide patterns. This shared architecture across both standard and long-wheelbase "L" models ensures that failure points like the active vibration cancellation mounts are consistent throughout the entire production range, requiring specialist knowledge for successful replacement.
Jeep Grand Wagoneer Models & Engines Codes
The Grand Wagoneer series utilizes specific engine families designed for heavy-duty luxury performance across all trims:
- Stellantis Hurricane (SST): 3.0L Twin-Turbo I6 (2022–present) – Intercooler efficiency issues affecting all WS variants.
- HEMI Eagle: 6.4L V8 (2022–present) – MDS (Multi-Displacement System) lifter failures common in early WS models.
- AMC 360: 5.9L V8 (SJ Platform, 1984–1991) – Shared oiling system vulnerabilities and carburetor manifold leaks.
- Hurricane HO: High-Output 3.0L (2023–present) – Shared turbocharger wastegate rattling across Series II/III luxury trims.
All powerplants in the WS generation share the Torqueflite 8HP75 transmission interface, meaning engine replacement requires precise ECU re-coding consistent across the entire Grand Wagoneer lineup.
Buy Used and Second-Hand Jeep Grand Wagoneer Engines
For Grand Wagoneer owners, used engines carry inherent risks due to shared generational failure patterns. We recommend:
- Remanufactured Hurricane Units: Essential for WS models to ensure upgraded cooling gaskets (Part 68444391AA) are installed.
- Reconditioned V8s: All 6.4L HEMI replacements should include revised MDS solenoids to prevent future cylinder deactivation faults.
- SJ Classic Rebuilds: Sourcing units with modernized seals to address the chronic oil leaks found in original AMC blocks.
Professional remanufacturing addresses these series-wide engineering flaws that standard "used" engines from salvage yards typically retain.

⚙️ Jeep Grand Wagoneer Engine Works: How Experts Rebuild Engines
When your engine fails, Jeep Grand 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. Grand Wagoneer-Specific Teardown & Inspection
The engine is stripped and all components are inspected for wear patterns unique to the Wagoneer's heavy-duty use, like cylinder scoring from towing loads on the Hemi V8.
2. Block & Head Machining for Large SUV Tolerances
The cylinder heads are resurfaced and valve guides replaced, critical for the 3.6L Pentastar's known oil consumption. Blocks are honed to factory specs for the high compression ratios.
3. Critical Internal Component Replacement
All timing components (chains, phasers, guides) are replaced with updated Mopar kits. For the 5.7L/6.4L Hemi, new valve seats and hardened exhaust valves are installed to prevent drop-in.
4. Turbo & Forced Induction System Refurbishment
For the 3.0L Hurricane I6, both turbochargers are inspected, balanced, and often fitted with new cartridges. All charge air coolers and piping are pressure-tested for leaks.
5. Reassembly with Updated Technical Service Bulletins
Engine is rebuilt using updated TSB parts, like the revised PCV system for the Pentastar V6 (TSB 09-001-21). All bolts are torqued in sequence to Stellantis factory specifications.
6. Dyno Break-In & Final Validation
The rebuilt engine undergoes a controlled dyno run-in cycle to seat rings and verify power/torque output matches the Grand Wagoneer's specific calibration before installation.
