Fan Clutch How It Works

Common fan clutch problems.

Tower fan cleaning. A cars fan is designed to enhance the radiators cooling efficiency by pulling extra air through the radiator at low vehicle speeds. This is when the fan clutch does not work properly and thereby decreasing the car air conditioners performance as the fan clutch also cools the condenser of the air conditioning unit. Detailed animations show internal components.

The most common problem encountered with a fan clutch is when the car overheats while it is not running. The fan clutch is an automatic device that is often used in a vehicles cooling system. 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. As temperatures increase the clutch engages so that the fan is driven by engine power and moves air to cool the engine. So when the engine is cool or even when it is at a normal operating temperature the fan clutch will partially disengage the engines radiator cooling fan which is mechanically driven.

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. This type of clutch is a lot like the viscous coupling sometimes found in all wheel drive cars. This important part of the cooling.

A properly functioning fan clutch is critical to engine reliability as it works to maintain a safe temperature range. How fan clutches work. Learn what makes a viscous fan clutch operate.

The fluid in the clutch gets thicker as it heats up causing the fan to spin faster to catch up with the engine rotation. I also heat the bimetal spring to show how that works. Be a learn engineering supporter or contributor.

Your engine will overheat if not for the fan clutch. A fan clutch is attached to the front of an engine on rear wheel drive cars and trucks only. This is normally found at the front of the water pump and it is driven by a belt and pulley that is connected to the.
