Understanding the Serpentine Tensioner Pulley
The serpentine tensioner pulley is designed to maintain tension on the serpentine belt, which drives various components such as the alternator, power steering pump, and air conditioning compressor. A properly functioning tensioner is essential to prevent belt slippage, which can lead to premature wear or even failure of these components.
Types of Serpentine Tensioner Pulleys
There are generally two types of tensioner pulleys:
- Mechanical Tensioners: These rely on a spring mechanism to maintain tension. They are common in older vehicles and are relatively straightforward to replace.
- Hydraulic Tensioners: More common in modern vehicles, these use hydraulic pressure to maintain belt tension. They are usually more complex and may require special tools for installation.
