OEM Part Number: 21410BA60A (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 68735 / Valeo 701762

Accuracy note: Covers the Nissan Juke (F15 2010-2019) as listed in the UK aftermarket catalogues. Radiators are sold by engine, gearbox and air-conditioning fitment, and one model usually has two or three different cores — a thicker core for diesels and automatics, a thinner one for small petrols — with different hose positions, so a radiator for the wrong engine will not connect up. The references below are UK aftermarket listings whose fitment lists name this generation, labelled by brand with the core size in mm; genuine numbers are those quoted against the listing. Check your engine code and whether the car has air conditioning against your VIN, and replace the coolant and bleed the system after fitting.

Radiators (aftermarket)	Nissens 68735 (380 x 584 x 16 mm, aluminium core, plastic tanks, 35 mm connections, supplied with seals, fits 1.6 HR16DE 94, 98, 113 and 117 PS including CVT); Valeo 701762; Denso DRM46079; NRF 58236; Mahle CR 856 000S; Van Wezel 13012717; Hella 8MK 366 312-121; Prasco DS300R001. Nissens 68741 (380 x 598 x 16 mm, aluminium core, plastic tanks, 35 mm connections, fits 1.6 HR16DE 113 and 117 PS, shared with Cube and Tiida)
Core sizes & variants	The 1.6 petrol takes a slim 16 mm crossflow core, with 68735 (OE 21410BA60A) covering every 1.6 output and 68741 the older 21410 1JY0A fitment; the 1.5 dCi diesel uses a taller, thicker 480 x 428 x 26 mm radiator. The 1.6 DIG-T turbo is not on these fit lists.
Genuine (OE) numbers quoted	1.6 petrol: 21410BA60A; 214101JY0A; 21410EE000; 21410EW000; 214101FD5A; 214101FD0A; 214101KF5A; 21410EE50A. 1.5 dCi: 214101FE0A; 214101FE0B; 21410BA62A
Fitment notes	68735 is sold with seals and is the broadest-fit petrol radiator

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.

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.

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.

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.
