Nissan Juke Radiator: OEM Part Number
| 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 |
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 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.
Nissan Juke Radiator: The Part That Keeps Everything Else From Cooking
Few parts get less attention than this one, but on the Nissan Juke, 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.
Nissan Juke Radiator: What It Does
On the Nissan Juke, 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.
