Belt tensioner for toyota rav4

Types of belt tensioner for Toyota RAV4

A Toyota RAV4 belt tensioner is a spring-loaded pulley device that maintains the correct tension on engine belts. Without it, the belts would become too loose or too tight. A belt tensioner consists of a pulley and a force-exerting element, which is usually a spring. The pulley allows the belt to ride on it, while the spring exerts a force between the pulley and the body of the tensioner. This force pulls the belt in the correct direction to maintain tension.

The Toyota RAV4 belt tensioner is available in different types, including the following:

• Manual belt tensioner: This type of tensioner can be adjusted manually. It has a screw that turns in either direction to loosen or tighten the belt. The manual tensioner is usually found in older vehicles.
• Spring-loaded belt tensioner: The spring-loaded belt tensioner uses spring tension to keep the correct amount of pressure on the belt. The spring exerts a constant force on the tensioner pulley, which maintains the right tension on the belt. One notable thing about this tensioner is that it needs to be replaced every 60,000 miles.
• Fixed pulley belt tensioner: This type of tensioner uses a fixed pulley to maintain the correct tension on the belt. The fixed pulley is placed at a specific distance from the crankshaft. This distance creates enough friction to keep the belt tight.
• Hydraulic belt tensioner: The hydraulic tensioner uses engine oil pressure to maintain tension on the timing belt. This type of tensioner is commonly found in high-performance and heavy-duty vehicles.
• Constant tensioner: A constant tensioner uses a coil spring to keep the tension level on the belt constant. This tensioner is often used in applications where the belt is subjected to a lot of movement.
