Jeep Liberty Engine ReplacementCompare Prices & Save

Typical rebuilt engine prices for Jeep Liberty range from £950 for early 2.4L petrol units to £3,200 for 2.8L CRD diesel engines, supply only. Supply & fit adds £400-£900 depending on location and workshop rates.

• 2.8L CRD rebuilt: £1,450-£3,200 supply only
• 3.7L V6 rebuilt: £1,200-£2,800 supply only
• Used engines start around £950 but carry higher risk

Only factory-fitted engines are guaranteed compatible: 2.4L/3.7L petrol PowerTech or 2.5L/2.8L VM Motori CRD diesel. Engine codes must match your VIN plate to avoid fitment issues.

• KJ (2002-2007): ED1/ED2 petrol, R425/R428 diesel, EKG petrol
• KK (2008-2012): EKG/EGQ petrol, ECN/AVM diesel variants
• Cross-generation swaps require ECU and wiring modifications

The 2.8L CRD delivers strong torque but has known weaknesses: rocker arm wear at 80k-120k miles and injector seal leaks. Rebuilt units with upgraded components address these issues.

• Rocker arm failure is the most common catastrophic issue
• Black Death injector seals cause carbon buildup if neglected
• Regular oil changes with correct spec extend engine life significantly

Engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty from UK specialists. Some suppliers offer extended terms for rebuilt or remanufactured units.

• 12-month unlimited mileage is the network standard
• Warranty covers parts and labour for manufacturing defects
• Always confirm terms with your chosen supplier before ordering

Yes, our UK network includes specialists offering supply-only or full supply & fit services for Jeep Liberty engines, with nationwide delivery and mobile fitting options available.

• Supply & fit adds £400-£900 to engine price typically
• Mobile fitters available in many regions for complex diesel installs
• Collection and delivery services offered by most suppliers

Supply-only engines can be dispatched within 1-3 working days. Full supply & fit typically takes 2-5 days depending on workshop availability and parts sourcing.

• Used engines often available for next-day dispatch
• Rebuilt units may require 3-5 days for final testing
• Complex diesel installs (2.8L CRD) take longer than petrol swaps

Copper injector seat seals degrade over time, allowing diesel to leak into the cylinder head and burn, creating hard carbon deposits that can seize injectors and damage the head.

• Failure typically occurs between 70k-110k miles
• Early signs include diesel smell in engine bay and rough idle
• Prevention includes regular injector seal inspection at service intervals

For Liberties worth £2,000-£5,000, a rebuilt engine with warranty often offers better value than repeated repairs or scrapping. Compare quotes before deciding.

• Rebuilt engines typically cost £1,200-£3,200 supply only
• Factor in vehicle value, mileage and intended ownership period
• Warranty coverage provides peace of mind for long-term use

KJ Liberties (2002-2007) use ED1/ED2 (2.4L petrol), R425 (2.5L diesel), R428/AR (2.8L diesel) or EKG (3.7L petrol). Match the code on your VIN plate exactly.

• R428 is the most common 2.8L CRD code for UK KJ models
• AR/AVM are export-spec variants with different emissions hardware
• Petrol codes EKG/EGQ are interchangeable within generation

Technically possible but not recommended: requires ECU, wiring harness, transmission and 4WD system modifications. Cost often exceeds vehicle value; stick with factory-spec replacement.

• Petrol-to-diesel swaps need extensive electrical reprogramming
• Transmission bellhousing and mounts differ between engine types
• Specialist conversion shops charge £3,000+ beyond engine cost
