Renault Scenic 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 |
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.
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.
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.
