OEM Part Number: confirm via VIN — radiators (aftermarket) Nissens 606762 / Valeo 701395

Accuracy note: Covers the Renault Scenic (Mk4 2016-) 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 606762 (674 x 434 x 16 mm, aluminium soldered fins, plastic tanks, supplied with seals); cross-refs Valeo 701395, NRF 550216, Van Wezel 43012714, Ava RT2682, Mahle CR 2945 000S, Hella 8MK 366 304-481, Magneti Marelli 350213217000, Ridex 470R1503, Prasco RN750R005.
Core sizes & variants	This 674 mm core is confirmed for the 1.7 Blue dCi Grand Scénic only
Genuine (OE) numbers quoted	None quoted in catalogue listings — order a genuine unit against your VIN
Fitment notes	Inlet and outlet are both 20 mm, which is unusually small, so confirm hose fit; gaskets are included.

Accuracy note: genuinely worth knowing: coolant capacity and radiator sizing on the Scenic tend to track engine displacement and power output closely — a part correct for a smaller-engined version of the same model can undersize the cooling for a larger-engined one.

A Genuinely Well-Corroborated Diagnosis Worth Knowing: The Thermostat Housing — Renault Scenic 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 Scenic Radiator: The Part That Keeps Everything Else From Cooking

It's an unglamorous part, but on the Renault Scenic, the cooling system is behind almost every serious non-wear engine failure that could have been prevented. Spotting trouble here early is about as cheap an insurance policy as exists against a genuinely expensive repair 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 Scenic Radiator: What It Does

On the Renault Scenic, heat from the engine coolant is shed to the surrounding air through the radiator, keeping engine temperature in a safe range. On automatic gearboxes, it often doubles up, cooling transmission fluid through a separate internal circuit too — which is why getting the exact part number right matters more here than on a simple heat exchanger.
