Motor Fan Shroud 214811HW3A for Nissan Micra/Versa 2012-2019 1.6L

Motor fan shroud 214811HW3A is the cooling fan and its moulded housing for the Nissan Micra K13 and the Versa, and it is sold as one assembly because the motor is riveted into the shroud rather than bolted. The shroud seals against the radiator core with a soft lip, which matters on these cars: without the lip the fan pulls air from the engine bay instead of through the core, and the gauge climbs in traffic even though the blade is turning.

The motor is a single speed brushed unit with a two pin plug on the right hand side as the unit sits in the car. Failure is gradual. The brushes wear, the motor draws more current, the 40 amp fuse in the battery box gets hot, and eventually the fan stops. Owners often report that the fan works when tapped with a screwdriver handle and stops again a minute later, which is the classic worn brush symptom. A blade that has lost a vane will vibrate and can crack the shroud around the motor mount.

Before replacing the assembly, confirm that the fan relay clicks when the engine reaches temperature and that the earth wire from the shroud to the body is clean. On the Micra the relay lives in the intelligent power distribution module, and a failed relay gives exactly the same dead fan as a failed motor.

Fitting takes about forty minutes. Disconnect the battery, remove the two 10 mm bolts at the top of the shroud, tilt the assembly forward, unplug the motor and lift it out between the radiator and the engine. The new unit goes in the same way, with the locating tabs at the bottom engaging the radiator tanks first. The cooling system is not opened, so nothing needs refilling, but run the engine afterwards and watch the fan cut in.

Supplied as one shroud and motor assembly, ready to fit. Twelve month warranty.
