Which is better thermal or non thermal fan clutch?

Which is better thermal or non thermal fan clutch?

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.

What is the difference in fan clutches?

A Standard Duty fan clutch will lock up 60 to 70 percent when engaged. A Heavy Duty fan clutch will lock up 70 to 80 percent when engaged. A Severe Duty fan clutch will lock up 80 to 90 percent when engaged. Standard Duty fan clutches are usually installed on cars and light trucks designed with good air flow.

What is the difference between a heavy duty and severe duty fan clutch?

Heavy Duty fan clutches turn the fan at 70 – 90% shaft speed. Severe Duty Fan Clutches have the same operation as Heavy Duty fan clutches. The difference between them is in the “Working Area”. As a fan clutch spins, it creates heat, the larger the working area the easier the heat is dissipated.

Will a bad fan clutch make noise?

3. Decrease in power, acceleration, and fuel efficiency. A decrease in performance is another symptom of a bad or failing fan clutch. A faulty fan clutch that leaves the fan permanently engaged will not only cause a noisy engine, but can also cause a decrease in performance.

What makes a fan clutch go bad?

BAD CLUTCH If your fan clutch is not operating the way it should, it’s likely due to a fluid leak or a bad thermostatic spring or valve. When a leak occurs, it’s at the bearing seal, at the center rear of the clutch.

How can you tell if a 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.

At what temperature should a fan clutch kick in?

Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.

Can a fan clutch cause overheating?

Overheating engine is the most common symptom of a bad or failing fan clutch. It controls the operation of the cooling fans. These cooling fans will disable/not work at maximum efficiency as the bad clutch will not engage properly. This result in overheating which may lead to serious issues if not timely attended.
