Fan Clutch Assembly

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD and 2019 Nissan NV2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

A cooling fan clutch is utilized to control cooling fan operation. This fan clutch is controlled by the ECM. The ECM monitors coolant temperature and intake manifold temperature to determine when to engage the cooling fan. There are also additional sensors monitored by the ECM for fan control (for example, air conditioner pressure). The fan clutch is an electro-viscous fan clutch.
