The Land Rover Defender 110 P500 V8 is an engineering marvel, but its 5.0L supercharged V8 operates under extreme thermal and mechanical loads. The AJ133 / 508PN engine dominates replacement demand for high-performance Defender 110s, primarily due to coolant system and supercharger-related failures. Rebuilt engines through EnginesMarket include upgraded components addressing these original failure points, plus a minimum 12-month unlimited-mileage warranty.

Vehicle Value Check
Vehicle Value Check
A typical Land Rover Defender 110 P500 V8 (2022-present) currently holds a value of £80,000-£120,000+ in the UK [THIRD-PARTY]. This places it firmly in the £15,000+ band, meaning a £8,000-£12,000 rebuilt engine replacement is a small fraction of the vehicle's worth and is highly recommended to preserve this ultra-premium asset. Flag: Safe.
Our Recommendation
Our Recommendation
For isolated coolant leaks, specialist pipe replacement with upgraded components is viable. However, given the vehicle's value and the complexity of the cooling system, a full rebuild with upgraded coolant components is the most reliable long-term solution.
