While all auto parts are designed with durability and reliability in mind, they don't have the same general life span. In fact, several components will wear out faster and, therefore, require more frequent replacements. Here are three of the most important ones to keep in mind.

What Auto Parts Need Routine Replacement?

1. Battery

The battery serves many critical functions. It delivers the needed energy to start the engine, provides power for the short-term use of lights and other features when the engine isn't running, and functions as a surge protector for a modern vehicle's sophisticated computer system. 

Most batteries last about three or four years before they naturally deteriorate and can no longer start the engine. You'll know a new one is in order if the engine struggles to start. Headlights or interior lights frequently dimming or flickering can also indicate a replacement is necessary.

2. Alternator

An alternator takes energy from the crankshaft and transforms it into electrical power for the battery and other components, like lighting systems and heated seats. It generally has a life span of about seven years, which equals anywhere between 80,000 and 150,000 miles. A dashboard warning light, a slow starting engine, or a suddenly and frequently stalling vehicle will help determine whether a new alternator is needed.

3. Timing Belt or Chain

The timing belt or chain synchronizes the movement of the crankshaft and camshaft. Essentially, it keeps the fuel injectors, pistons, and air intake moving in the right directions at the correct times to ensure proper engine performance.

If this auto part snaps, you could be left with significant engine damage. Therefore, have it checked at 60,000 miles to see if it needs a replacement. Be alert for ticking sounds from under the hood or an engine that won't turn over, as these are signs of a bad timing belt or chain.
