What is the difference between thermal and non-thermal clutch fan?

What is the difference between thermal and non-thermal clutch fan?

Non-thermal clutches operate solely based on the shaft speed of the water pump. A non-thermal clutch provides a steady flow of cooling air but is always engaged, so it offers lower fuel savings than a thermal-style fan clutch. However, non-thermal clutches are a lower-cost option than thermal-style clutches.

What is the purpose of a thermostatic clutch fan?

A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

Is Turkish cotton better than Egyptian?

How do I know if my thermal fan clutch is bad?

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.

What is thermal fan?

Thermal Fan Clutch As engine temperature varies, a temperature-sensitive bimetal coil spring expands or contracts, opening or closing non-return inlet and outlet ports between the hydraulic reservoir and the clutch cavity. When the engine is cold, the non-return drain valve opens, and draws oil back into the reservoir.

Is a straight fan better than a clutch fan?

When compared to an electric fan, fan clutches are quite inefficient. The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.

Can you drive with a bad fan clutch?

If your fan clutch is frozen on full lock (and i would guess it is, since it roars all the time and has bad mileage and no balls), i would say it?s fine for you to drive it for the time being. If the clutch wasn?t locking up anymore, now that would be different (the fan wouldn?t cool properly).

At what temperature does a fan clutch engage?

about 170øF
Answer: Most fan clutches engage at about 170øF air temperature (about 180-190øF engine temperature). They reduce the temperature about 20øF before disengaging.

What?s the difference between thermal and non-thermal fan clutches?

The Difference in Thermal Vs. Non-Thermal Fan Clutches. Clutch driven fans run quieter, whereas direct-driven standard fans eat up horsepower and increase noise at high engine rpm. In addition, a fan clutch reduces wear by decreasing fan speed and raising the engine?s operating temperature rapidly during start-up.

What are the different types of fan clutches?

There are two types of fan clutches available: thermal and nonthermal. Both thermal and nonthermal clutches are filled with silicone based oil. The low viscosity oil channels energy to the fan by transferring centrifugal hydraulic pressure from the clutch housing cavity to fluid coupling teeth and the clutch plate.

How does a fan clutch work on a radiator?

As hot air blows across the radiator, it heats a thermal spring mounted at the front of the clutch. As the spring is heated, it turns and allows valve ports to open within the clutch. Silicone fluid stored inside a reservoir is allowed to pass through these open ports and enter the working area of the clutch.

How does a thermal and nonthermal fan work?

How Clutch Fans Work Both thermal and nonthermal clutches are filled with silicone based oil. The low viscosity oil channels energy to the fan by transferring centrifugal hydraulic pressure from the clutch housing cavity to fluid coupling teeth and the clutch plate.
