Why Does Your Car's Serpentine and V-Belts Make Noise When It's Cold or Damp?

Hello, dear readers! We're glad to have you here on King's Auto Repair blog. As the mercury dips and the humidity rises, we've noticed a common query among our customers - "Why does my car belt squeak when it's cold or damp?" Today, we'll address this concern in detail, providing you with the comprehensive, professional insight you've come to expect from us.

Firstly, let's understand what we're dealing with. The serpentine and v-belts, also known as drive belts, are vital components of your car's engine. They power various accessories like the alternator, power steering pump, air conditioning compressor, and sometimes even the water pump.

But why do they make that annoying squeaking noise, particularly when the weather is cold or damp?

The primary reason is belt slippage. Cold or damp conditions can cause the belt to lose its grip on the pulleys it's attached to. This slippage results in a high-pitched squeal or squeak that you hear, especially during the initial startup. The moisture from the cold or damp conditions acts as a lubricant, reducing the friction between the belt and pulleys, leading to slippage.

Moreover, the rubber material of the belts tends to harden and become less flexible in cold temperatures. This rigidity makes the belts more prone to slipping and squealing.

A weak belt tensioner coupled with a hardening rubber of the belt can also cause the belt to slip, making noise.

While this noise is a common occurrence and may not necessarily indicate a severe issue, it's essential not to ignore it. Persistent noise could be a sign of wear and tear, indicating that the belt and/or tensioner might need replacement. Other signs of a worn-out belt include visible cracks, frayed edges, or missing chunks from the belt.

At King's Auto Repair, we recommend regular inspections of your serpentine, v-belts and tensioner, especially during the cold and damp seasons. Regular checks can help identify any potential issues early, preventing expensive repairs down the line.
