The cold weather causes rubber to be less pliable and a bit brittle. As the engine pulleys turn the rubber belt at a very rapid pace, this will cause them to squeak a bit until the rubber material warms up and becomes more pliable. This may also happen when the belt needs to be tightened up.

How long can you drive with a squealing serpentine belt?

That's why it's recommended that the serpentine belt is replaced early when the squealing symptoms are first noticed. Although it may be safe to drive with the squealing for a few days or weeks, the belt will eventually need to be replaced, and for safety, the earlier it's repaired, the better.

How many years should a serpentine belt last?

The serpentine belt "snakes" around several components of the engine, transferring mechanical power to nearly every critical part. Under normal conditions, the belt needs to be replaced every 4 to 6 years.

What are problems that can cause a belt to squeal?

The belt squeals because there is improper tension in the belt drive system. This is usually caused by a worn automatic tensioner, but other causes can include a contaminated belt (oil, belt dressing, etc.) or a belt that is too long or worn out.

Will a serpentine belt squeal while idling?

The idler pulley has to be strong enough to hold the serpentine belt in place with the right tension as it spins. If it doesn't, the belt may slip, and the annoying squeal will start. Call a mechanic to check the tension on the idler pulley. See also: car heater blow cold air when idling.
