Range Rover 4.4 V8 Engine Replacement Compare Prices & Get Quotes

A full rebuilt or reconditioned engine replacement for a Range Rover 4.4 V8 typically ranges from £6,500 to £12,000 for supply only, depending on whether it is the petrol (AJ-V8) or diesel (448DT) variant. Used engines start around £2,500 but carry higher risk, while rebuilt units include upgraded components and a 12-month warranty.

The most common early warning signs in the Range Rover 4.4 V8 are unexplained coolant loss, a sweet smell from the engine bay, or a distinct rattling noise on cold starts pointing to timing chain wear. For the 448TDV8 diesel, watch for oil/coolant mixing or illuminated temperature warning lights.

It depends heavily on the vehicle's overall condition. A typical Range Rover 4.4 V8 holds a UK market value of £3,000-£8,000. If the chassis, bodywork and interior are in pristine, low-mileage condition, a £6,500-£12,000 rebuilt engine is a sound investment to preserve a classic flagship. If the vehicle is heavily worn, evaluate scrap or part-exchange value first, as the rebuild cost may exceed the car's worth.

A professional supply and fit service for a Range Rover 4.4 V8 typically takes 3 to 5 days, depending on the specialist's workload and whether any ancillary components like the cooling system are being upgraded simultaneously. Sourcing a quality rebuilt V8 unit may add a few days.

The Range Rover 4.4 V8 petrol (AJ-V8, 2002-2005) is a naturally aspirated unit prioritising smooth, refined power delivery and simpler mechanical architecture. In contrast, the 4.4 TDV8 diesel (448DT, 2006-2009) is a twin-turbocharged unit focused on massive low-end torque, heavy towing capability, and improved fuel economy, though it carries more complex cooling system components.
