3. Clutch Type: Thermal vs. Non-Thermal
Alright, let’s get a little technical, but don’t worry, I’ll keep it simple! There are two main types of fan clutches: thermal and non-thermal (also known as torque-limiting or viscous). Thermal clutches are the most common type and use a temperature-sensitive fluid to engage the fan based on the air temperature passing through the radiator. Non-thermal clutches, on the other hand, engage based on engine speed and torque.
Thermal clutches are generally more efficient in terms of fuel economy because they disengage the fan when it’s not needed. They’re also better at maintaining a consistent engine temperature. Non-thermal clutches, while less fuel-efficient, can provide more consistent airflow and are often preferred in heavy-duty applications where constant cooling is required. Consider the pros and cons of each type based on your vehicle’s needs and driving style. Understanding this difference is key to finding the best performance engine fan clutches.
4. Engagement Speed and Smoothness
Have you ever felt that jarring “thunk” when your fan clutch engages? That’s something you definitely want to avoid!
