Do fan clutches need to be broken in?

New clutches do not require time to ‘break in’. Our OEM fan clutches are the fluid engagement type (viscous fan clutch). The way I understand it as the temperature increases the fluid valve opens (linearly with temperature) causing the viscous fluid to fill the outer rim of the clutch causing the fan to spin faster.

How can I tell if my fan clutch is working?

To confirm the diagnosis, start with this simple test: Spin the fan as hard as you can on an engine that has not been started that day. If the fan rotates more than five times, you can bet the clutch is bad. You should feel some resistance and the fan may spin up to three times, depending on the ambient temperature.

Why does my clutch fan wobble?

If there is any wobble in the fan, there is a bad bearing in the fan clutch, or a worn bearing on the water pump shaft. A bad water pump bearing will usually cause the water pump to leak and/or make noise, but not always. Remove the fan clutch and see if the play is in the water pump shaft.

When do you know it’s time to replace the fan clutch?

According to Hayden, here are some signs your fan clutch might need replaced: Fan spins excessively when engine is stopped (three or more times when hot engine is shut off). Poor A/C performance at idle or low vehicle speeds. Fan speed does not increase when engine is hot.

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 happens to the fan clutch at high speeds?

At low and idling speeds, the clutch allows the fan blade to turn at almost a 1:1 ratio. At high speeds, the silicone fluid within in the clutch will lose its ability to transfer the energy from the shaft to the fan clutch body (and therefore, the fan) and the fan is then allowed to almost free-wheel, removing its load from the engine.

How do you remove a clutch fan?

Loosen the the fan clutch using a 32mm wrench. The threads are reverse rotation, so turn it CLOCKWISE to loosen. Once the fan clutch is loose, remove the wrench, spin the fan clutch the rest of the way off with your hand. Once the fan is completely off carefully fish it out from between the engine and the radiator, it may take a little force.

How do fan clutches work?

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. This allows the engine to operate more efficiently by removing the load that the fan places on it.

What is a fan clutch?

A fan clutch is a device found on an automobile’s cooling fan . In most cases, the fan is attached to the fan clutch by four bolts. As the engine speed increases, the fan clutch disengages and puts the fan into a free-wheeling mode.
