Jeep Engine Replacement - Compare Prices & Save

A complete Jeep engine replacement typically costs between £2,500 and £4,500 for common four-cylinder diesel units like the 2.0L MultiJet II (Renegade, Compass) and £4,000 to £6,500 for the 3.6L Pentastar V6 (Wrangler, Grand Cherokee). Reconditioned engines usually sit in the middle of those ranges, while premium remanufactured units with upgraded components (e.g., revised piston rings on the Pentastar, uprated chains on the MultiJet) can reach £5,500-£8,000. Supply-and-fit adds £400-£900 to the engine price depending on the model. For an accurate price tailored to your registration number and engine code, use our free comparison tool. *

Four key factors determine the final price: engine size and complexity (a 3.0L CRD V6 diesel costs significantly more than a 1.3L FireFly petrol); condition - used, reconditioned, or remanufactured; vehicle age and complexity (Wrangler JL access is easier than Grand Cherokee WK2, affecting labour hours); and supply-only vs supply-and-fit. Geographic location also matters - London and South-East labour rates can be 20-30% higher than the national average. Our marketplace shows you transparent, all-in quotes from multiple UK Jeep specialists so you can see exactly what affects each price. *

In most cases, yes - especially if the chassis, transmission, and bodywork are in good condition. A properly rebuilt Jeep engine with upgraded components (e.g., improved piston rings on a Pentastar, an aluminium oil cooler on a 3.0L CRD) often outlasts the original. Compare that to spending £15,000-£30,000 on a replacement vehicle of similar age and spec. For sought-after models like the Wrangler JK, Grand Cherokee WK2, or a well-maintained Cherokee XJ, engine replacement is almost always financially sensible. The only time we advise against it is if the rest of the vehicle has severe structural rust or irreparable electrical faults. *

A full supply-and-fit service includes sourcing the correct engine (by engine code, not just model), removal of the old unit, installation of the replacement, all new gaskets, seals, fluids and filters, a workmanship warranty (typically 12 months), and disposal of the old engine. Most specialists also include a road test and final inspection. Fitting costs generally range from £450-£900 depending on the model - the Grand Cherokee WK2 is towards the upper end due to its complex front subframe design. Always confirm what’s included before committing: some quotes exclude ancillaries like the alternator, starter, or turbo. *

For common models like the Cherokee KL, Compass MP, or Renegade with MultiJet II or Tigershark engines, a straightforward swap takes 3-5 working days. More complex models - especially the Wrangler JK (2.8L CRD) or Grand Cherokee WK2 (3.0L CRD or 3.6L Pentastar) - can take 5-7 days due to accessory removal and subframe alignment. The biggest variable is engine availability: our network of UK specialists holds stock of the most commonly replaced codes (e.g., Pentastar 3.6L, MultiJet 2.0L/2.2L, 3.0L CRD), so lead times are often shorter than going to a main dealer. Ask each supplier for their current turnaround when you request a quote. *

Yes - every engine supplied through EngineMarket carries a minimum 12-month unlimited mileage warranty as standard. Rebuilt and remanufactured units (the highest grade, with all critical components replaced to factory spec) often come with extended 24-month or 36-month coverage. The warranty typically covers major internal components: crankshaft, connecting rods, pistons, piston rings, cylinder head, valves, camshafts, timing chain or belt, and oil pump. It usually excludes ancillary parts (injectors, turbo, alternator) unless explicitly rebuilt as part of the engine. Always confirm exact terms with your chosen supplier before purchase. *

Used engines are cheaper upfront - typically £1,200-£2,500 for common Jeep units - but they come with unknown history and minimal warranty (often 30-90 days). They’re a good choice for a temporary fix or if you plan to sell the vehicle quickly. Reconditioned engines cost more (£2,500-£5,500) but include new piston rings, bearings, gaskets, and often upgraded components that address the original failure point (e.g., revised timing chain tensioners on MultiJet II, uprated oil cooler on 3.0L CRD). For long-term ownership - especially on failure-prone engines like the 2.2L MultiJet or early 3.6L Pentastar - a reconditioned or remanufactured engine with a 12-24 month warranty is almost always the better investment. *

EngineMarket connects you with a UK-wide network of independent Jeep engine specialists, from Scotland to the South Coast. While there’s no single dominant regional hub for Jeep in the way Land Rover has the Midlands, we see strong clusters of 4x4 specialists around Manchester, Birmingham, Bristol, and Essex - many of whom benchmark their work against main dealers but charge 30-50% less. Enter your registration number, and we’ll match you with up to three suppliers who stock your specific engine code and offer supply-only or supply-and-fit. Nationwide delivery is available if you prefer to use your own garage for fitting. *

The most common catastrophic failures driving replacement are: timing chain stretch on the 2.0L and 2.2L MultiJet II diesels (Cherokee, Renegade, Compass), often failing by 80,000 miles; oil cooler housing cracks on the 3.0L CRD (Grand Cherokee WK2), which mixes oil and coolant and kills the turbo and main bearings; excessive oil consumption and valve seat drop on early 3.6L Pentastar V6 engines (2011-2013 Wrangler JK, Grand Cherokee); MultiAir brick failure on the 2.4L Tigershark (Renegade, Cherokee, Compass) and 1.3L FireFly; and crankshaft bearing failure on the 2.8L CRD (Wrangler JK) following injector failure and fuel dilution. These failures rarely give enough warning for a cost-effective repair - engine replacement is the most common outcome. *

Always compare at least three quotes - prices for the same engine code can vary by £1,000 or more between suppliers. Consider used if your budget is tight and you only need 12-24 more months from the vehicle. Choose reconditioned or remanufactured for long-term ownership, especially on failure-prone engines where upgraded components prevent a repeat failure. Ask for supply-only if you have a trusted local garage - you’ll save the specialist’s fitting markup. Finally, check what’s included: some headline prices exclude VAT, delivery, or critical ancillaries like the oil pump and timing chain. Our marketplace makes all this transparent so you can compare apples-to-apples. *
