- A cooling fan clutch (1) 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 and transmission temperature). The fan clutch is an electro-viscous fan clutch.
