How much does a Range Rover P440e engine replacement cost-

A full reconditioned or rebuilt Range Rover P440e engine typically costs between £4,500 and £10,000 for the unit itself, depending on the level of rebuild.

What are the signs of cooling system failure in a Range Rover P440e-

Early detection is critical to preventing catastrophic damage to your AJ20P6 engine. Look for unexplained coolant loss, overheating warnings on the dashboard, or a sweet smell from the engine bay. The PHEV system may also limit electric mode availability if thermal management is compromised.

Is it worth replacing the engine in a Range Rover P440e-

Yes, absolutely, given the high retained values of the L460 PHEV Range Rover lineup. A rebuilt AJ20P6 engine with upgraded water pumps and cooling components can extend the vehicle's life significantly. For vehicles valued over £80,000, a warranted reconditioned engine protects your investment far better than a cheap used unit.

Does the P440e engine replacement include the high-voltage hybrid battery-

No, the engine replacement covers the AJ20P6 internal combustion unit only. The high-voltage battery is a separate component. However, our vetted specialists are trained to safely disconnect, protect, and reintegrate the hybrid system during the engine swap.

How long does a Range Rover P440e engine replacement take-

A straightforward supply and fit of a reconditioned AJ20P6 engine typically takes 3 to 5 days at a specialist workshop. This allows time for high-voltage system safety protocols, proper bedding-in procedures, ECU calibration, and a thorough road test.

Common Problems

Range Rover P440e Engine Problems Repair Cost vs Replacement

The Range Rover P440e is celebrated for its seamless blend of electric torque and refined inline-six performance. The AJ20P6 / 306PS 3.0L Ingenium petrol engine is the core internal combustion unit driving replacement demand for this variant. Rebuilt engines supplied through EnginesMarket include upgraded components, such as revised water pumps and cooling system seals, addressing the original failure points, plus a minimum 12-month unlimited-mileage warranty.

Common failure points and repair options

Cooling System & Water Pump Failure

Affected: Range Rover P440e (AJ20P6 / 306PS, 2022-present)
Typical failure mileage: 60,000-100,000+ miles

Root cause

Plastic water pump impellers or housing cracks can lead to coolant loss and subsequent overheating, a risk slightly exacerbated by the additional thermal management demands of the PHEV battery cooling system.

Repair options

Repair tier	Dealer price	Specialist price
Preventative Cooling System Service	£800-£1,500	£500-£1,000
Full Replacement - rebuilt/reconditioned engine	£10,000-£14,000	£6,500-£10,000

Our recommendation

If your Range Rover P440e is exhibiting early signs of coolant loss or minor boost irregularities, a preventative specialist service is a cost-effective solution. However, if the engine has suffered severe overheating or internal damage, a full reconditioned replacement is the most reliable long-term investment to preserve the vehicle's performance and value.

Turbocharger & Crossover Pipe Leaks

Affected: Range Rover P440e (AJ20P6 / 306PS, 2022-present)
Typical failure mileage: 70,000-120,000 miles

Root cause

Thermal cycling can cause plastic coolant crossover pipes to become brittle and leak, while turbocharger seals may wear over time, leading to boost loss or coolant ingestion.

Repair options

Repair tier	Dealer price	Specialist price
Turbo & Pipe Service	£1,500-£2,500	£900-£1,800
Full Replacement - rebuilt/reconditioned engine	£10,000-£14,000	£6,500-£10,000
