Transmissieoliekoeler voor het transmissiekoelcircuit op V8-benzinemotoren.

De koeler reguleert de temperatuur van de automatische of handmatige transmissievloeistof door vloeistof door een speciale warmtewisselaar te leiden, waardoor transmissiecomponenten worden beschermd tegen warmtegerelateerde slijtage. Geplaatst binnen het koelsysteem van de motorruimte, ontvangt deze vloeistof van de transmissie en retourneert deze op een verlaagde temperatuur.

Frequently asked questions

What does the ESR1703 transmission oil cooler do?
The ESR1703 transmission oil cooler regulates transmission fluid temperature on V8 petrol Discovery 1 and Range Rover Classic models. It routes fluid through a heat exchanger and returns it cooler, protecting the gearbox from heat-related wear. It suits both manual and automatic transmissions.
Which vehicles does this cooler fit?
The ESR1703 fits the V8 petrol Discovery 1 and Range Rover Classic, in both manual and automatic transmission applications. It mounts in the engine bay cooling system. Confirm your model has the V8 petrol engine before ordering, as cooler specifications differ by drivetrain.
What thread fitting does the ESR1703 use?
The ESR1703 transmission oil cooler uses an M20 x 1.5 thread for its fluid connections. Match this against your existing cooler unions and adapters before fitting to the Discovery 1 or Range Rover Classic V8.
What are the signs a transmission oil cooler needs replacing?
A failing transmission oil cooler typically leaks fluid, corrodes, or becomes internally blocked, causing the transmission to overheat on the V8 Discovery 1 or Range Rover Classic. Overheated fluid accelerates gearbox wear, so check for leaks and reduced cooling if temperatures climb.
