A car’s engine needs access to intake air as well as the ability to release exhaust. These two factors allow an engine’s internal combustion reaction to continue unabated; ultimately, the timing belt is what makes this possible. To maintain proper engine function, here are three signs your timing belt is going bad to look out for.
What a Timing Belt Does
On its face, a timing belt is a small loop of toothed rubber. While it doesn’t appear complex, it handles a very important and precise interchange. A timing belt turns the crankshaft and camshafts so that intake and exhaust engine valves open and close at specific times. If these valves opened and closed unpredictably, the engine’s performance would suffer and damage is possible.
Typically, manufacturers recommend changing your timing belt between 90,000 and 105,000 miles, though that can vary by make and model. To track the condition of your car’s timing belt before it reaches this mileage threshold, know the following signs your timing belt is going bad.
You Hear a Ticking Sound
As your timing belt rubber wears down, you may hear a ticking sound at the front of your car. While this can be a symptom of something else, such as low motor oil, it’s best to visit a mechanic to determine what exactly is going on with your belt.
Your Engine Misfires
If your engine doesn’t receive intake air properly due to timing belt deterioration, it may skip a combustion step and misfire. In the moment, a misfire involves a loss of power from the engine and inconsistent vibration and bucking. You may smell something off and hear unexpected sounds from your engine.
You Can’t Start Your Car
Also, your timing belt is an important element of your ignition system. When you go to start your car, while you may hear your starter, your crank and camshafts will not engage. This means you can’t start your car due to timing belt failure.
While it’s important to acknowledge these symptoms could result from other part failures, it is possible a timing belt problem lies at the heart of your troubles. When these warning signs arise, it’s best to talk to a professional.
