Nissan Note Radiator: Specs, Fitment & Common Faults

On the Note, 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 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: radiator core size and construction can differ between petrol and diesel Note engines, and again between manual and automatic gearboxes where the automatic needs an integrated oil cooler circuit — confirm your exact engine code and transmission before ordering.

A Genuinely Useful Diagnostic Point Worth Knowing: No Drip Doesn't Mean No Leak — Nissan Note 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.

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.
