OEM Part Number: H1BG8005AB (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 606662 / Valeo 701286

Accuracy note: Covers the Ford EcoSport (2013-) as listed in the UK aftermarket catalogues. Radiators are sold by engine, gearbox and air-conditioning fitment, and one model usually has two or three different cores — a thicker core for diesels and automatics, a thinner one for small petrols — with different hose positions, so a radiator for the wrong engine will not connect up. The references below are UK aftermarket listings whose fitment lists name this generation, labelled by brand with the core size in mm; genuine numbers are those quoted against the listing. Check your engine code and whether the car has air conditioning against your VIN, and replace the coolant and bleed the system after fitting.

Radiators (aftermarket)	Nissens 606662 (385 x 546 x 22 mm, aluminium core with plastic tanks, fits all 1.0 EcoBoost outputs and the 1.5 EcoBlue 4x4); Valeo 701286; Denso DRM10123; Mahle CR 1181 000S; NRF 550068; Van Wezel 18012722; Ava FD2681; Hella 8MK 366 301-831
Core sizes & variants	Both EcoSport radiators share the same 385 x 546 x 22 mm core, so the difference is in the tanks and connections: the 606662 type has two 34 mm connections and covers petrol and diesel, while the 606661 type has a 34 mm and a 38.5 mm connection and is listed for the higher-output 1.0 EcoBoost cars. The hose size on the old radiator decides which one is needed.
Genuine (OE) numbers quoted	2088142; 2101532; 2178100; H1BG8005AB; H1BG8005CB; H1BG8005DA (606662 type); 2101513; 2055474; 2375964; GN118005CB; GN118005CD (606661 type)
Fitment notes	Both Nissens units are supplied with seals and without expansion tank or cap. Check the hose diameters before ordering as the two types are otherwise the same size.

Accuracy note: genuinely worth knowing: automatic gearbox EcoSports typically need a radiator with a built-in transmission oil cooler that manual versions don't have — ordering the manual-spec part for an automatic car will fit, but won't cool the gearbox oil properly.

The 1.0 EcoBoost's Degas Bottle Is a Genuine, Documented Weak Point — Ford EcoSport Radiator

Across the 1.0 EcoBoost family generally (primarily 2012-2017 production), the plastic degas bottle (coolant reservoir) and its connecting hoses have a well-documented tendency to develop hairline cracks as the plastic ages and heat-cycles over years of use — serious enough that a UK Parliament transport committee document specifically references "failure of the degas pipe affecting 1.0L Fox engines" as a known issue Ford was asked to address. Watch for dropping coolant levels requiring more than one top-up between services, a sweet smell from the engine bay, or white smoke from the exhaust on starting — all worth investigating promptly rather than simply topping up and continuing to drive.

Worth knowing: a genuine UK recall (reference R/2020/089, 2020) also covered certain Kuga and Puma models specifically for a related coolant leak risk — worth checking your own registration via the DVSA recall checker even if your model wasn't part of that specific recall, since the underlying degas bottle weak point affects the wider 1.0 EcoBoost range.

Ford EcoSport Radiator: The Part That Keeps Everything Else From Cooking

Unglamorous as it is, the Ford EcoSport's cooling system sits behind nearly every serious engine failure that isn't just ordinary wear — and one that went unaddressed for too long. Noticing early warning signs here is a small cost against a potentially very large one.

Before you buy: radiator size and design vary significantly by engine size, transmission type, and whether your car has air conditioning. Always confirm against your VIN before ordering.

Ford EcoSport Radiator: What It Does

On the Ford EcoSport, engine coolant sheds its heat into the passing air via the radiator, which is what keeps engine temperature in a safe working range. On automatics, it frequently pulls double duty cooling the transmission fluid through its own internal circuit — a detail that makes getting the exact part number right especially important.
