Land Rover Part Number: ESR3687 - Radiator with Oil Cooler - V8 Automatic
ESR3687 is a radiator with an integral oil cooler for V8 petrol automatic vehicles. Fitted to the cooling system of V8 petrol automatic Discovery 1 models and some Range Rover 3.9/4.2 V8 EFI automatic models, the unit transfers heat from engine coolant to ambient air and provides a separate oil cooler circuit to manage oil temperature. The core routes coolant across finned passages where airflow reduces coolant temperature before it returns to the engine, while the built-in oil cooler passes oil through separate passages so the same airflow can remove excess heat. The assembly mounts at the front of the engine bay and interfaces with the fan shroud, hoses and mounting brackets specific to V8 petrol automatic layouts; regular inspection for leaks, blockages or damage helps maintain correct coolant and oil temperatures during normal and heavy-load operation.
