For many years the PJ (J section) profile was only used for industrial applications, as drive belts for washing machines and tumble dryers. Recently, these small V-Ribbed belts were introduced in the automotive industry, where the main applications are ventilator (fan) drives.
Usually the basic engine configuration only has 1 fan, which is electrically driven (system installed on radiator). In case additional cooling is needed (cars with air conditioning, with a factory installed tow bar, for taxis, etc.), a second fan is installed in order to pull more cooling air through the radiator. This second fan is then often driven from the first by a 2 or 3 rib PJ belt.
Features & Benefits:
Recently introduced in the automotive industry where its main application is ventilator (fan) drives
Used on cars that need additional cooling and a second fan to pull more cooling air through the radiator
Service Tip: Always replace belts and tensioners together. Old tensioners will reduce a belt's lifespan, and can lead to issues such as overheating, a dead battery, diminished power steering, or poor air conditioning performance.
