Renault Twingo Radiator: OEM Part Number

Manual gearbox, all engines	Standard radiator with no transmission cooling circuit
Automatic/EDC dual-clutch, all engines	A genuinely separate water-oil heat exchanger cools the transmission fluid, distinct from both the radiator itself and the separate engine oil cooler also present on many of these engines — confirmed as three distinct cooling components working together, not one radiator doing all the jobs

Accuracy note: genuinely worth knowing: radiator core size and construction can differ between petrol and diesel Twingo engines, and again between manual and automatic gearboxes where the automatic needs an integrated oil cooler circuit — confirm your exact engine code and transmission before ordering.

A Genuinely Well-Corroborated Diagnosis Worth Knowing: The Thermostat Housing — Renault Twingo Radiator

If your car has the 0.9 or 1.2 TCe engine and you're chasing a slow coolant leak, this is genuinely worth knowing directly: one owner's own assessment after extensive research put it plainly — "95% chance it is thermostat housing." This is a well-documented, common failure point on these engines, and genuinely good news on cost: one documented repair came to around £85-100.

A genuinely useful diagnostic insight worth knowing: a coolant leak that seems to disappear entirely over summer, then returns once temperatures drop in winter, is a real, documented pattern — rubber components expand slightly when warm, which can temporarily seal a very small crack or hole, only for it to re-open as the material contracts in colder weather. If your leak seems to have "fixed itself" only to return months later, this genuinely explains why.

It's also genuinely worth knowing you're not imagining a problem if this feels like a common complaint: multiple owners and independent motoring columns have confirmed that this generation of small turbocharged engines leaks coolant in significant numbers, and if a dealer is dismissive of a genuine, repeated coolant loss without a proper investigation, it's worth pushing back rather than accepting a simple "topped up, no fault found" response.

Renault Twingo Radiator: The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but on the Renault Twingo, 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.

Renault Twingo Radiator: What It Does

The Renault Twingo'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.
