Dacia Jogger Radiator: Specs, Fitment & Common Faults

On the Jogger, a genuine, widely-documented thermostat housing fault comes with a real consumer grievance worth knowing.

Generation covered: this guide is for the Jogger (launched 2021), with particular focus on 2021–2023 registered examples now old enough for parts to be a common search. Check your logbook or VIN if you're unsure which build you have.

Confirmed: A Genuine, Widely-Documented Thermostat Housing Fault — And a Real Consumer Grievance

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.

A genuinely useful, free diagnostic technique worth trying first: rather than removing the engine undertray immediately, shine a torch up through the gaps toward the thermostat housing and look for visible staining, crusting, or wetness — this can often confirm a leak without needing to remove anything.

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.

The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but 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.

OEM Part Numbers

Accuracy note: genuinely worth knowing: whether a Jogger has air conditioning or a larger optional engine can change radiator sizing on some variants — fitment guides that only ask for model and year can still get this wrong, so cross-check the engine code where possible.

The Jogger shares its CMF-B platform with the Dacia Sandero and Renault Clio, so it's worth checking parts listings under those car names too. Radiator specification varies between the manual TCe versions and the automatic Hybrid 140/155, which has additional cooling requirements for its hybrid system components.

What It Does

The 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.

Fitment & Compatibility

Radiators differ between manual and automatic versions of the Jogger due to the transmission cooling circuit, and again across different generations. A radiator designed for a manual gearbox car will not correctly cool an automatic's transmission fluid even if it physically fits the mounting points. Always confirm the exact part number for your specific engine and transmission combination. Whether you're sourcing a replacement radiator for your Dacia Jogger from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying.
