Can I shift with a fan on?
Yes, you can shift with a fan blowing.
How does a water pump fan clutch work?
The fan clutch is a thermostatic device, which means it operates based off temperature, and is usually mounted on the water pump, or another belt driven pulley. The fan clutch will spin loosely until the temperature reaches a certain level, at which point the fan clutch will fully engage…
When to replace the fan clutch in your cooling system?
When replacing the damaged water pump, it is wise to replace the worn fan clutch at the same time otherwise the new water pump will soon fail. That is why the fan clutch should be replaced when a water pump is replaced. How to tell if the Fan Clutch in your Cooling System is failing or has failed.
How does silicone fluid affect the fan clutch?
During high speed rotation the silicone fluid within the fan clutch reduces its ability to spin the fan at full speed and the energy transferred from the water pump shaft, through the clutch to the fan is reduced. The result is less load on the engine as the fan almost free-wheels.
How does a non thermal fan clutch work?
Non-Thermal Fan Clutches. Non-thermal clutches operate solely based on the shaft speed of the water pump. At low and idling speeds, the clutch allows the fan blade to turn at almost a 1:1 ratio.
What does a fan clutch do on a water pump?
A fan clutch is a temperature-controlled coupling between the water pump shaft and the fan which allows the fan to be operational at low speeds and disconnected at higher speeds.
What should I do if my fan clutch is not working?
More likely, you’re going to have to remove the shroud. This means draining some coolant, disconnecting the upper radiator hose and sometimes removing the belt. If the clutch is held to the belt pulley hub by screws or bolts, use a plumber’s strap wrench to keep the pulley from turning while you loosen the screws.
What are the different types of fan clutches?
Types of Fan Clutches. The main types are non-thermal, thermal, and electronic — all of which use a silicone fluid to engage and disengage your fan. Non-thermal clutches operate solely based on the shaft speed of the water pump. At low and idling speeds, the clutch allows the fan blade to turn at almost a 1:1 ratio.
What is the RPM of a fan when disengaged?
When disengaged, it turns the fan at 25-35 percent. It’s used with deeper-pitch fans (2 1/2″ of pitch), and works well with higher operating rpm. Severe-Duty Thermal Fan Clutch: Severe duty thermal fans turn the fan at 80-90 percent of the shaft speed when engaged and 20-30 percent when disengaged.
