Common failure points and repair options

Cooling System & Water Pump Vulnerability

Affected: Land Rover Discovery P360 (AJ20P6 / 306PS, 2021-present)
Typical failure mileage: 60,000-120,000 miles (projected based on Ingenium family patterns)

Root cause

Plastic coolant crossover pipes and electric water pump components can degrade under repeated heat cycles, leading to coolant loss and potential overheating if not addressed promptly.

Repair options

Repair tier	Dealer price	Specialist price
Preventative Cooling System Service	£800-£1,500	£500-£900
Full Replacement - rebuilt/reconditioned engine	£9,000-£14,000	£6,500-£10,000 [EM-QUOTE]

Our recommendation

Proactive inspection and replacement of the electric water pump and coolant crossover pipes is a highly recommended, low-cost preventative measure. If overheating has already occurred, a full rebuilt engine replacement is the safest and most reliable solution to protect your investment.
