The timing belt is responsible for turning the crankshaft and ensuring each cylinder fires at the right time. However, unlike many other auto parts, this belt is sealed inside its own housing deep inside your vehicle, so even knowledgeable drivers may not know where it is or how to know when it’s failing. While timing belt trouble may not always be obvious, below are a few signs it may be time for a replacement.

4 Signs You Need a New Timing Belt

1. The Car Won’t Start

A variety of problems, from a dead battery to fouled spark plugs, can keep your car from starting. However, if you’ve eliminated other common causes of an engine that won’t turn on, the problem might be a broken  timing belt.

2. Poor Engine Performance

A worn timing belt sometimes slips on the pulleys, which throws the pistons and valves out of alignment. While your vehicle will still run, the engine might stutter and shake, and you might notice backfires and an overall loss of performance.

3. Squealing Sounds

Loud, screeching sounds under the hood might be caused by other belts, which are some of the easiest auto parts to replace. However, if the sound occurs at random intervals, regardless of whether you’re idling or cruising down the highway, you might be hearing a worn timing belt rubbing against the pulleys.

4. The Check Engine Light Is On

A failing timing belt causes problems throughout the engine, which will usually cause the check engine light to come on. Because a broken timing belt always results in extensive damage to other auto parts, have your check engine light diagnosed by a professional immediately.
