Land Rover Part Number: LR066866 - Rear Evaporator
LR066866 is a rear evaporator fitted within the heater and air conditioning internal assembly; it provides refrigerant-to-air heat exchange specifically for the rear seat climate control system. Refrigerant passing through the evaporator changes phase and absorbs heat from cabin air blown across the evaporator core, lowering temperature for rear-seat occupants. Replacement is normally required when the core corrodes, leaks refrigerant, or becomes blocked with debris, causing reduced cooling performance or refrigerant loss. Accessing and replacing the rear evaporator involves the HVAC internal components and the refrigerant circuit and should be carried out by technicians certified to handle refrigerant systems.

Frequently Asked Questions
LR066866 is the cold-side heat exchanger for the rear-seat air conditioning circuit; it removes heat from cabin air as refrigerant evaporates inside the core. The evaporator is integrated into the HVAC internal assembly and the vehicle's refrigerant circuit. Common failure modes are corrosion, refrigerant leaks or blockage by debris, all of which reduce cooling performance; any work on the evaporator requires certified refrigerant handling.
