Why does the radiator fan have to start when turning the A/C on?.

. The fan clutch is a coupling device that is located between the water pump shaft and the fan. The fan clutch is designed to improve the vehicles cooling system efficiency while reducing the load on the engine and loss of energy caused by the fan itself. The Fan Clutch allows the fan to operate at lower speeds and effectively detach at higher. Pusher fans should be the same diameter or smaller than the air conditioning condenser. A larger fan can cause air to pass through the open area. Although you can use two small fans, one large fan 14 16 typically works better. If you are able to use two pusher fans, 12 or larger, two fans generally work better than using only one.

. Mar 23, 2022 So, if the fan clutch is spinning freely, it means it is going bad and you might even hear a squeal from the clutch. However, if you have an electronic fan clutch, then it might freewheel even when its cold. If your fan clutch is spinning freely, perhaps the thermostatic spring has given up. Feb 26, 2017 In a nutshell: The radiator fan comes on so the A/C works at its highest efficiency. The A/C condenser the part which sits in front of the coolant radiator is a heat exchanger. If air isn#39;t flowing over it, it won#39;t exchange the heat it needs get rid of so the A/C core inside the vehicle can become cold and make you comfortable.

. This small structure can wear out after prolonged use. Once you replace the relay, the radiator fan should start working again. Temperature Sensor. The ECU#x27;s job is to start the radiator fan once the engine reaches a certain temperature. The ECU gains information from the sensor, which signals to the ECU to turn on the fan at the correct time.

Symptoms of a Bad or Failing Cooling Fan Relay - YourMechanic.

The V-belt drove the fan through a pulley system by friction, consequently, as the belt stretched through wear, it could start to slip. Tell-tale signs were overheating in traffic, as the fan and water pump were not turning at the correct speed.

Fan Clutch Replacement - Popular Mechanics.

Feb 13, 2007 My client currently is using belt driven fan. Many maintenance work have been done for the belt, but it still fails quite often. So they want me to change it to direct drive coupling. The original belt driven fan has a faster speed than motor and the sheave ratio is not 1:1. The fan is a little bit faster than motor.

9 Cooling System Myths and Mistakes Plus Helpful Cooling.

Mar 19, 2009 I am having overheating problems, and I have a belt driven fan. I just realized that the fan spins even with the belt on. It spins very freely, and the belt is tight. Just the fan spins the water pump pulley doesnt spin with it. Is that normal? I am trying to diagnose my cooling problems.

Should A Fan Clutch Spin Freely When Cold? - Vehicle Freak.

Engine fan with viscous drive. 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. First, let#x27;s describe a situation where an alternator is being underdriven. Measuring across your crank pulley, you get 6 inches. And your alternator pulley is 2 1/2 inches in diameter. Six.

Your Radiator Fan Stopped Working - Here Are The Next Steps To Take.

Blown Fuse. If your cooling fan circuit fuse has blown, this is another sign of a problem with the radiator fan motors. If your motors fail or surge unexpectedly, then this can cause the fuse to blow. The fuse will blow to protect the rest of the system from further damage due to the unforeseen electrical surges.

5 Reasons Why Your Car Cooling Fan Is Louder Than It Should Be.

1 Pay attention to changes in air temperature. One of the most common symptoms of a fan clutch on the outs is an inability to properly cool the air circulating through the vehicle. Switch on the A/C and turn it down to the coldest setting. Belt Drive. Defined: In a belt driven configuration, the motor exists independently of the fan blades and at least one belt - sometimes more - connects the motor to the fan#x27;s moving parts. Pro: Belt driven fans offer greater flexibility in terms of RPM speed. Generally, such fans are cheaper than direct drive fans of comparable size.

The difference between direct drive fan and belt drive fan.

Radiator Cooling Fans. Cooling fans are driven by the engine#x27;s crankshaft or by an electric motor. They provide airflow through the radiator fins, transferring heat from the engine#x27;s coolant to the outside air. The radiator does not operate effectively without proper airflow. This airflow is vital, especially while idling or traveling slowly. The fans are the default included with the case, not sure what name. Something worth noting is that today the back case fan didn#x27;t start for the first time usually the front ones. The only fiddling I#x27;ve done with the fans in the Bios is to change the setting from #x27;auto#x27; to #x27;dc#x27;, but that didn#x27;t seem to change anything.

Jun 5, 2015 Sounds like a belt driven fan with a thermostatic clutch. When coolish, it will still spin but the clutch is not engaged. If you#39;re daring enough, you can actually stop the fan with a finger. When things heat up the thermostatic clutch kicks in and actually drives the fan. I wouldn#39;t recommend trying to stop the fan with anything then. A belt-driven fan will typically require at least 3 12 inches between the water pump and the radiator, while our Low Pro electric fan requires only 1.09 inches at the center where your pulley is.
