Frequently asked questions

What does the ESR3685 radiator do on a Defender V8?
The ESR3685 radiator is the primary heat exchanger in the engine cooling system on the V8 petrol Defender. Mounted at the front, it dissipates heat from the coolant as air passes through the core, connecting to the cooling circuit at its top and bottom hose unions.
Which engines does this radiator fit?
The ESR3685 fits the Land Rover Defender with the 3.5L V8 twin-carburettor or 4.0L V8 EFi petrol engine, covering roughly 1987 to 2006. It does not fit 300Tdi or Td5 diesel engines. The 3.5L V8 application with oil cooler runs from VIN TA976036.
What are the signs a Defender radiator needs replacing?
Common signs include coolant leaks, overheating, and visible corrosion or fins clogged with debris. On these V8 Defenders the radiator sits at the front and works hard in slow traffic. If the engine runs hot or you're topping up coolant regularly, the radiator is a likely cause.
What's the difference between the ESR3685 and ESR1678 radiator?
The ESR3685 lists ESR1678 as its alternative radiator for the V8 petrol Defender. They're cross-referenced for the same application, so either can typically be used. Confirm your engine type and hose union positions match your original before ordering.
