Land Rover Part Number: ESR203 - Radiator Assembly
ESR203 is a Radiator Assembly. Fitted to Defender models with the Td5 engine, this radiator transfers heat from engine coolant to ambient air via a finned core and inlet/outlet tanks. It provides mounting points for the fan shroud, connections for the upper and lower coolant hoses, and interfaces with the coolant reservoir and thermostat housing within the front cooling pack. On vehicles without an oil cooler the radiator retains standard coolant routing and hose locations. Core damage, internal blockage or tank failure will reduce cooling capacity and typically requires replacement; when fitting a replacement confirm hose routing and fan shroud alignment to avoid restricted airflow or hose interference.

Frequently Asked Questions
The ESR203 radiator moves heat from engine coolant to ambient air through a finned core and inlet/outlet tanks, returning cooled fluid to the engine circuit. It carries the fan shroud mounting and upper/lower hose connections and interfaces with the coolant reservoir and thermostat housing. Common failure modes are core damage, internal blockage or tank failure which reduce cooling capacity; these faults normally require replacement and should prompt inspection of hose routing and shroud alignment during refit.
