How To Change The Ac Fan Belt Inside?

This guide explains how to remove and replace a fan belt on a HVAC/Furnace/Exhaust/AC system (Roof Top Air Conditioner/PTAC Unit). A cracked, broken, or loose AC belt can prevent the AC fan from spinning, which is common with older AC condenser models. It is usually caused by simple wear and tear. Replacing an AC belt can be challenging, as you need to locate specific parts in the car and use proper tools to complete the task.

In this video, the author shows how to install a new air conditioner belt in a 1999-2006 Chevy Silverado. An attic fan draws hot air out of the top of a home and vents it outside. A broken fan belt stops the motor from engaging the fan blades and must be replaced if the attic fan is to function properly. The belt runs under the crank pulley, up over the alternator and tensioner pulleys, and around the fan pulley. The belt is tensioned by loosening the tensioner 2.

To replace your air conditioner fan belt, turn off the power and disconnect the air conditioner from the power source for safety. Access the belt by removing the cover or panel to access the fan belt. Carefully remove the old belt, noting its placement and tension. The correct way to replace a belt is to turn off the air conditioner and disconnect it from the power source. If the serpentine belt breaks, the car’s AC will stop functioning, along with the cooling fan, water pump, and power steering.
