Here Are Three Warning Signs That Point To A Faulty Fan Clutch Car Owners May Not Notice On Time
The cooling system’s fan clutch regulates the rotational velocity of the engine’s cooling fans. For cooling purposes, older automobiles relied on a mechanical fan clutch, whereas modern vehicles often use electrically powered fans. The fan clutch is a thermostatic mechanism attached to the water pump or a similar belt-driven pulley that determines when to engage and disengage. As soon as the desired temperature is attained, the fan’s clutch fully engages, allowing it to operate at peak efficiency. But, there are indicators your car will give you if the fan clutch is failing or has been damaged and needs to be serviced. According to Mechanicbase, here are three warning signs that point to a faulty fan clutch car owners may not notice on time.
An overheated engine.
An overheating engine is one of the first signs of a broken fan clutch. Inadequate coolant or a broken radiator are two common causes of engine overheating, but a malfunctioning clutch can have the same effect and is often overlooked by drivers. As a first line of defense, many drivers will try to add coolant to the radiator in the hopes that it will allete the car’s overheating symptoms. The fan clutch, however, is universally acknowledged as the primary component in regulating the speed with which the cooling fans spin. If the fan clutch fails, the fans won’t spin and the cooling system won’t work as well.
Secondly, a drop in efficiency Frequently, the cooling fan clutch fails because it becomes stuck and cannot turn. In this method, the water pump’s shaft and the fan’s axis of rotation will always be in lockstep with one another. The engine won’t overheat, but it also won’t perform at its best. As a result, the engine loses efficiency and power because of the higher resistance to forward motion. Loss of speed, power, and efficiency is one of the most noticeable signs.
Third, the air conditioner’s fan system is rather noisy.
When turning the air conditioner on or off, drivers almost never hear strange noises like roaring or clicking. Some causes of that squeaky sound include low differential oil, old tires, or broken wheel bearings. A common culprit is the fan’s clutch. You can’t drive the car if the clutch shoe becomes stuck. The fan, thus, is permanently attached to the input shaft.
