| Core sizes & variants | The pre-2018 petrol TCe and 1.5 dCi cars share one 510 x 388 mm main radiator; the Euro 6d Blue dCi 95 introduced in 2018 moved to a slightly taller 405 mm core with its own genuine number. All diesel versions also carry a narrow 83 mm auxiliary radiator for the charge-air circuit, which is a separate part. |

| Fitment notes | Main radiator connections are 35 mm; the auxiliary radiator has 19 mm connections. The TYC unit is listed for manual-gearbox cars only, so Easy-R automated cars should be checked against the VIN. |
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: 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.
