Frequently asked questions

What does the ESR3687 radiator do?
The ESR3687 is the engine coolant radiator for V8 automatic applications, the main heat exchanger in the cooling system. It's a cross-flow radiator with side tanks and includes an internal transmission oil cooler in the tank to cool the automatic gearbox fluid.
Which models does the ESR3687 V8 auto radiator fit?
This radiator fits the Discovery 1 V8 petrol automatic (1989-1998, up to VIN MA081992) and the Range Rover Classic 3.9 and 4.2 V8 EFi automatic (1986-1994). It cross-references to ESR2630, AU2099 and ESR1250. Check your VIN, as the Discovery 1 has a build cut-off.
What are the signs this radiator needs replacing?
A failing V8 radiator usually shows as coolant leaks from the core or side tanks, overheating, or coolant and transmission fluid mixing if the internal oil cooler fails. Corrosion and blocked cores are common on older cars, and a cross-contaminated cooler risks gearbox damage.
