Nissan X-Trail Radiator: Specs, Fitment & Common Faults

On the X-Trail, an emptying coolant reservoir with no visible drip genuinely doesn't mean there's no leak — coolant can atomise against a hot component instead.

OEM Part Number: 214104BE0A (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 68788 / Denso DRM46065

Accuracy note: Covers the Nissan X-Trail (T32 2014-) 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 68788 (540 x 468 x 26 mm, aluminium core with plastic tanks, fits 1.6 dCi R9M, 2.0 dCi M9R, 1.6 DIG-T MR16DDT and 1.3 DIG-T HR13DDT); Denso DRM46065; Mahle CR 1595 000S; NRF 550119; Van Wezel 33002444; Hella 8MK 366 307-611; Prasco DS836R004.
Core sizes & variants	One 540 x 468 mm radiator covers the 1.6 and 2.0 dCi diesels and the 1.3 and 1.6 DIG-T petrols, including 4x4 versions, and is shared with the Renault Koleos II. The 2.0 and 2.5 petrol X-Trails sold outside Europe are not listed.
Genuine (OE) numbers quoted	214104BE0A
Fitment notes	Supplied with gaskets and seals, with 35 mm inlet and outlet connections.

Accuracy note: genuinely worth knowing: automatic gearbox X-Trails typically need a radiator with a built-in transmission oil cooler that manual versions don't have — ordering the manual-spec part for an automatic car will fit, but won't cool the gearbox oil properly.

A Genuinely Useful Diagnostic Point Worth Knowing: No Drip Doesn't Mean No Leak — Nissan X-Trail Radiator

If your coolant reservoir keeps emptying but you can't find a single drip anywhere underneath the car, this is genuinely worth knowing: coolant escaping and atomising against a hot component, such as a manifold or exhaust, rather than dripping straight down to the ground, is a real and well-documented possibility. The absence of a puddle in the garage doesn't mean the absence of a genuine leak.

Worth knowing on related models using the 1.3 DIG-T engine: the plastic thermostat housing on this engine has a well-known tendency to crack or shear off, sometimes leading to serious engine damage if a slow leak goes undetected for an extended period. If your specific car shares this engine, it's genuinely worth confirming with a specialist whether this fault applies to your exact variant.

It's also worth knowing that a genuinely useful, quick diagnostic technique is pressurising the coolant system directly, since some leaks — particularly around joints or hose connections that expand slightly when hot — only become visible under this kind of pressure test.

Nissan X-Trail Radiator: The Part That Keeps Everything Else From Cooking

It's an unglamorous part, but on the Nissan X-Trail, the cooling system is behind almost every serious non-wear engine failure that could have been prevented. Spotting trouble here early is about as cheap an insurance policy as exists against a genuinely expensive repair 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.

Nissan X-Trail Radiator: What It Does

On the Nissan X-Trail, heat from the engine coolant is shed to the surrounding air through the radiator, keeping engine temperature in a safe range. On automatic gearboxes, it often doubles up, cooling transmission fluid through a separate internal circuit too — which is why getting the exact part number right matters more here than on a simple heat exchanger.
