Nissan Juke Radiator: Specs, Fitment & Common Faults

A genuinely severe, well-documented fault on related models: over 40% of thermostat housing failures resulted in a full replacement engine, with costs ranging from £700 to £10,000.

OEM Part Numbers

Manual gearbox, all engines	Standard radiator with no transmission cooling circuit
Xtronic CVT, European/UK-spec cars	Genuinely uses a separate external "beehive"-style CVT oil cooler, air-cooled and mounted away from the main radiator — a different arrangement from the coolant-shared warmer fitted to North American-spec cars of the same model
Fitment note	CVT fluid temperature is known to run hot under sustained motorway driving or towing on this platform — confirm your exact market spec before assuming your car has (or lacks) the dedicated external cooler

Accuracy note: genuinely worth knowing: coolant capacity and radiator sizing on the Juke 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 Severe, Well-Documented Fault Worth Understanding — Nissan Juke Radiator

If your Juke shares the 1.3 DIG-T engine used across Nissan's related range, this is genuinely worth understanding: the plastic thermostat housing has a well-known tendency to crack or shear off, and documented tracking on related models has recorded cases where over 40% of affected cars ultimately needed a full replacement engine after a leak went undetected long enough to cause serious internal damage. Real cost figures worth knowing: a straightforward housing repair has been quoted around £700 out of warranty, while a full engine replacement following undetected damage has been quoted as high as £10,000. Failures have been documented across a genuinely wide mileage range, so this isn't limited to only very high-mileage examples.

A genuinely important consumer rights point worth knowing if a dealer resists a warranty claim: a thermostat housing is not a scheduled maintenance item — meaning a dealer's usual "it's just wear and tear" framing doesn't automatically apply the same way it might to a brake pad or filter. If you're facing resistance, it's genuinely worth pointing this distinction out directly.

A genuinely useful early warning sign worth knowing: an emptying coolant reservoir with absolutely no visible drips anywhere underneath the car has been documented repeatedly — coolant escaping and atomising against a hot component rather than dripping to the ground is a real possibility, so the absence of a puddle doesn't mean the absence of a genuine leak.

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.

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.
