OEM Part Number: 8V518005FA (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 69235 / Valeo 701603

Accuracy note: Covers the Ford Fiesta (Mk7 2008-2017) 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 69235 (352 x 544 x 24 mm, aluminium mechanically jointed core with plastic tanks, 28 mm inlet and outlet, supplied with seals; fits the 1.25 60 PS and 82 PS, 1.4 97 PS and 1.4 LPG, plus the B-MAX 1.4); Valeo 701603; Denso DRM10043; Mahle CR 1135 000S; NRF 53152; Van Wezel 18002440; Hella 8MK 366 301-801
Core sizes & variants	Both radiators share the same 352 x 544 x 24 mm core and 28 mm hose stubs; 69235 is the wide-fit part for the 1.25 and 1.4 petrols, while 69234 is the alternative listed for the 1.4 petrol and LPG only, so the engine code and the shape of the tank brackets decide between them. The 1.6 TDCi diesel and 1.0 EcoBoost use different radiators not covered here.
Genuine (OE) numbers quoted	1540332; 1566662; 1671561; 1775583; 1897437; 8V518005FA; 8V518005FB; 8V518005FC; 8V518005FD; ME8V518005FD
Fitment notes	Both Nissens parts are supplied with seals and have 28 mm inlet and outlet pipes.

The 1.0 EcoBoost's Degas Bottle Is a Well-Documented Weak Point

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 Fiesta Radiator: The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but on the Ford Fiesta, almost every serious engine failure that isn't wear-related traces back to a cooling system problem left unaddressed. Catching the early signs here is genuinely cheap insurance against a much bigger bill.

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 Fiesta Radiator: What It Does

The Ford Fiesta's radiator transfers heat from the engine coolant to the surrounding air, keeping engine temperature within a safe operating range. On automatic versions, it often also cools transmission fluid through a separate internal circuit — one more reason the correct part number matters so much here.
