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 Discovery P300 of relevant age (2017-present) currently holds a UK market value of approximately £25,000-£45,000 [THIRD-PARTY - Auto Trader market observations]. At this premium value band, a reconditioned or rebuilt engine replacement is a small fraction of the vehicle's worth and easily justifies the investment to preserve performance and resale value.
Our Recommendation
Our Recommendation
If your Land Rover Discovery P300 is exhibiting minor coolant seepage but has not suffered thermal damage, a targeted preventative cooling system refresh by a JLR specialist is the most cost-effective route. However, if the engine has overheated, a full rebuilt replacement is the only reliable long-term solution.

Don't Let Engine Failure Write Off Your Land Rover Discovery P300
Whether it is a cooling system leak or a timing chain rattle, addressing issues early keeps your Land Rover Discovery P300 on the road and protects its strong resale value.
