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 should I do if my fan clutch is on the outs?

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 causes radial streaks in a fan clutch?
Radial streaks are another potential clue—this happens when oil escapes from the clutch and is then blown outward in all directions by the fan. Inside the fan clutch, there is a small reservoir filled with a viscous silicone-based oil. The oil flows to and from the main chamber as engine heat fluctuates, engaging and disengaging the clutch.
What’s the best temperature to test a fan clutch?
Make sure your new fan clutch is the same type as the original. It’s possible to upgrade from a non-thermal clutch to a more efficient thermal model, but not the other way around. Keep your engine temperature below 210 °F (99 °C) while you’re running your tests to prevent it from overheating.
When to know if your car fan clutch is binding?
Activity that’s louder than normal may indicate binding. A binding fan clutch will typically be accompanied with warm air flow from the A/C, since the fan isn’t turning the way it should be. Start your vehicle and listen for the fan to engage. Give the engine a little time to warm up. After 4-5 minutes, the fan clutch should come to life.
