Engine beltsCooler temperatures cause a bigger drain on the battery, which means the alternator has to work harder, which in turn creates additional wear on the belts.

Power steering pumps also put a bigger load on the belts when the oil is cold. Because the belts are more brittle in cold weather, it's especially important to stay on top of belt maintenance. Any strange noises under the hood can be early indicators of trouble, so have them checked immediately to avoid being stranded somewhere.
