Nissan Pulsar Radiator: Specs, Fitment & Common Faults

On the Pulsar, 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: 214103ZU0A (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 606120 / Valeo 701699

Accuracy note: Covers the Nissan Pulsar (C13 2014-2018) 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 606120 (508 x 432 x 16 mm, aluminium soldered core, plastic tanks, 1.2 DIG-T petrol); Denso DRM46075; Valeo 701699; NRF 59267; Van Wezel 13012711; Ava DN2470; Prasco DS700R004.
Core sizes & variants	The 1.2 DIG-T Pulsar shares its radiator with the Juke F15 1.2 DIG-T. The 1.5 dCi diesel and the 1.6 DIG-T Pulsar take different radiators that were not confirmed here.
Genuine (OE) numbers quoted	214103ZU0A
Fitment notes	Inlet is 35.5 mm and outlet 28.5 mm. Diesel owners should order against the VIN.

Accuracy note: genuinely worth knowing: some Pulsar engines pair the radiator with an integrated oil cooler or a separate charge-air cooler depending on turbocharging — these aren't interchangeable, so confirm your exact engine spec before ordering.

A Genuinely Useful Diagnostic Point Worth Knowing: No Drip Doesn't Mean No Leak — Nissan Pulsar 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 Pulsar Radiator: The Part That Keeps Everything Else From Cooking

It's an unglamorous part, but on the Nissan Pulsar, 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 Pulsar Radiator: What It Does

On the Nissan Pulsar, 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.
