What is a Tension Pulley?

The tension pulley, also known as the idler pulley, is responsible for maintaining the tension of the serpentine belt in the 2020 Silverado. It is a crucial component that ensures the proper functioning of various engine accessories. The tension pulley is designed to rotate freely, providing the necessary tension to keep the belt in place.

Functionality of a Tension Pulley

- The tension pulley absorbs vibrations and prevents excessive belt movement, ensuring smooth engine operation.
- It maintains the proper tension in the serpentine belt, allowing efficient power transmission to the engine accessories.
- The tension pulley reduces slippage of the serpentine belt, preventing power loss and optimizing performance.
- It helps in extending the lifespan of the belt by minimizing wear and tear caused by inadequate tension.
- The tension pulley ensures that all engine accessories, such as the alternator, power steering pump, and air conditioning compressor, operate effectively.

What Happens When a Tension Pulley Goes Bad?

When a tension pulley goes bad in the 2020 Silverado, it can lead to various issues and potentially cause damage to the engine system. Here are some consequences of a faulty tension pulley:

Inadequate Belt Tension

A worn-out or malfunctioning tension pulley may not provide sufficient tension to the serpentine belt. This can result in belt slippage, leading to decreased power output and suboptimal functioning of engine accessories.

Belt Misalignment

When a tension pulley is faulty, it may cause the serpentine belt to become misaligned. This misalignment can lead to belt squealing, increased wear on the belt, and potential damage to other engine components.

Increased Noise and Vibrations

A bad tension pulley may produce abnormal noises such as squeaking, grinding, or rattling. Additionally, it may cause excessive vibrations, indicating a potential issue with the pulley or the belt.

Potential Belt Failure

If a tension pulley goes completely bad, it can result in the serpentine belt coming off or breaking. This can lead to a complete loss of power to the engine accessories, potentially leaving the vehicle inoperable.

When to Replace Tensioner Pulley?

It is essential to monitor the condition of the tensioner pulley in the 2020 Silverado and replace it when necessary. Here are some signs that indicate the need for a tensioner pulley replacement:

- Abnormal noises, such as squeaking, grinding, or rattling, coming from the engine area.
- Excessive belt movement or misalignment.
- Visible signs of wear or damage on the tensioner pulley, such as cracks or breakage.
- Increased vibrations that were not present before.
- Difficulty in operating engine accessories, such as power steering or air conditioning.
