Dacia Logan MCV 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 |
Confirmed: A Genuine, Widely-Documented Thermostat Housing Fault — And a Real Consumer Grievance — Dacia Logan MCV Radiator
If your car has a TCe petrol engine, this is genuinely worth knowing: the plastic thermostat housing on these engines has a well-documented tendency to crack or lift away from its gasket over time, causing coolant loss that can escalate to a serious leak. One genuinely alarming documented case on a related model saw the thermostat housing crack severely while driving on a motorway, emptying the entire cooling system. When the dealer diagnosed the cause, they refused warranty coverage, reportedly claiming this kind of failure "has never happened" — despite it being a widely reported, well-documented issue across owner forums for this exact engine.
It's also worth knowing about a genuine false positive: air conditioning systems naturally produce condensation, which can drip onto the ground in a way that's easily mistaken for a coolant leak. If you're seeing wet patches but the coolant level isn't actually dropping, it's worth checking whether this is simply normal AC condensate first.
Dacia Logan MCV Radiator: The Part That Keeps Everything Else From Cooking
Few parts get less attention than this one, but on the Dacia Logan MCV, a neglected cooling system is behind the vast majority of avoidable serious engine failures. Noticing the early warning signs costs nothing and can save a genuinely large repair bill down the line.
Dacia Logan MCV Radiator: What It Does
On the Dacia Logan MCV, coolant runs through the radiator to shed engine heat into the airflow, keeping temperatures in check. On many automatics, a separate internal circuit inside the same unit also cools the transmission fluid — one more reason a mismatched part number causes more than just a cooling problem.
