Cheap Mercedes-Benz GLE Oil Cooler

Yes, most GLE variants do have an engine oil cooler, and some also have a separate transmission oil cooler depending on the gearbox fitted. The oil cooler is present across petrol and diesel engine variants, though the exact type and location can differ between engine families. Always confirm which cooler you need — engine or transmission — before searching, as these are separate parts.

Almost certainly not without verification — the W166 generation ran from 2015 to 2019, while the current V167 generation launched for 2019, and the two platforms are mechanically distinct. Even if the engine code looks similar across the two generations, mounting points, pipework connections, and ancillary fittings can differ. Name both your generation and your engine code when contacting a breaker, and ask them to cross-reference against your registration before buying.

Yes — the 250d and 350d use different engine codes (the 250d uses the OM651 four-cylinder and the 350d uses the OM642 six-cylinder), and the oil cooler is matched to the engine, so the two are not interchangeable. Fuel type and engine code are the critical details here, not the badge or model name. Always quote your engine code, which you can find on your V5 or through a VIN check, when requesting a quote from a breaker.

No, trim level makes no difference to oil cooler fitment on the GLE — AMG Line, Sport, and other trim designations are cosmetic and equipment packages that do not change the engine or its ancillaries. What matters is that both vehicles share the same engine code, fuel type, and gearbox type. You may find minor cosmetic differences on the removed part such as brackets or heat shielding, so confirm these details with the breaker against your registration to be safe.

For the engine oil cooler specifically, the gearbox type is generally less critical than the engine code — the cooler serves the engine regardless of which gearbox is attached. However, if you are also looking for a transmission oil cooler, then gearbox type becomes the primary fitment factor. Confirm with the breaker which cooler you need and supply both your engine code and gearbox type to avoid any mismatch.

The W166 GLE ran from 2015 to 2019, and it is possible that ancillary components including mounting brackets, pipework connections, or the cooler itself were revised at some point within that production run. Because mid-production changes like this are difficult to pin down without checking against a specific VIN, you should not assume that any W166-sourced oil cooler will automatically fit without checking. Give the breaker your full registration or VIN so they can verify the part against your exact build date before purchasing.
