Confirmed: A Genuine UK Recall Covering Coolant Leaks on Certain Pumas

Worth checking directly against your registration: Ford issued a UK recall (reference R/2020/089, 2020) specifically covering certain Puma models alongside the Kuga for a potential coolant leak that could lead to engine overheating. Confirming this recall work has been completed via the official DVSA recall checker is a genuine priority rather than a nice-to-have — and given every Puma runs the 1.0 EcoBoost, it's also worth being aware of the wider degas bottle and coolant hose issues discussed below, which affect this engine family more broadly regardless of whether your specific car falls under the recall.

Broader context worth knowing: across the 1.0 EcoBoost family generally (primarily 2012-2017 production, though the Puma arrived later in the engine's life), the plastic degas bottle (coolant reservoir) and its connecting hoses have a well-documented tendency to develop hairline cracks as the plastic ages — 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.

The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but 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.

What It Does

The 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.

Fitment & Compatibility

Radiators differ between manual and automatic versions of the Puma due to the transmission cooling circuit, and again across different generations. A radiator designed for a manual gearbox car will not correctly cool an automatic's transmission fluid even if it physically fits the mounting points. Always confirm the exact part number for your specific engine and transmission combination. Whether you're sourcing a replacement radiator for your Ford Puma from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying.

Common Faults

Symptoms of Failure

Engine temperature gauge creeping up — often the earliest sign, especially noticeable in slow traffic or on long motorway runs.
Sweet-smelling smoke from the engine bay — a strong indicator of a coolant leak, usually from a cracked radiator tank or failed seal.
Visible coolant puddles under the front of the car — points to a leak that needs tracing back to its source before it causes overheating.
Milky discolouration in the coolant reservoir — can indicate a more serious internal issue where coolant and oil are mixing, requiring urgent inspection.

DIY Replacement Difficulty

This is a moderate-to-difficult DIY job, typically involving draining the cooling system, removing the front bumper or grille on some model years for access, and correctly bleeding air from the system afterward. Getting the bleed process wrong can cause airlocks that mimic a still-faulty radiator, so this is one job where following the exact procedure matters. Expect 2–3 hours for an experienced home mechanic, or roughly 1–1.5 hours of labour at a garage.

OEM vs. Aftermarket

OEM radiators are generally the safer choice given how directly this part affects engine longevity, though reputable aftermarket brands with genuine OEM-equivalent specifications are a reasonable, cheaper alternative. Budget unbranded radiators are where most repeat-failure complaints cluster — this is not a part worth cutting corners on.
