Tips for Identifying Timing Belt Problems in Your Lexus

by Mechanics Direct August 3, 2024

Is there a high-pitched sound coming from your Lexus as you drive? If yes, then it may be a sign that the timing belt is wearing out or touching some parts of the engine it shouldn’t come in contact with. Although it may be considered a trivial matter, it is not. Recognizing this sign early and addressing it will save you a lot of stress you’d have experienced when your Lexus breaks down due to a faulty timing belt.

What Does Timing Belt Mean?

The timing belt is made of high-quality rubber that has teeth on one side to allow it to engage the gears of the engine. It links the crankshaft and the camshaft to make sure that both of them move in harmony. This belt is important to your engine as it ensures the engine valves open and close at the right time during the combustion process. The belt silently does its job and starts wearing out gradually owing to heat, friction, and age and if left unchecked it may lead to engine problems.

Symptoms of a Bad Timing Belt

• Ticking Noise: If you feel or hear a ticking sound coming from your engine, then it is high time that you get your timing belt checked for replacement. The sound originates from the belt wearing or getting out of place.
• Engine Misfires: When the timing belt begins to deteriorate it could cause your engine to misfire. This occurs because the valves of the engine become out of time and thereby fire the cylinders If your Lexus is having poor engine performance and you frequently see engine misfires then there might be a problem with the timing belt.
• Rough Idling: A damaged belt will make your engine vibrate when it is idle. This shaking or vibrating may also be followed by sounds that you have not heard before. The vehicle will idle roughly because the camshaft and crankshaft are not well synchronized.
• Check Light: Check engine light may appear for several reasons, and one of them is the problem with the timing belt. If you see the light on, particularly accompanied by other signs that we have discussed earlier, then it is time to take your Lexus to the mechanic for an inspection of the timing belt.
• Engine Won’t Start: If the timing belt cuts as you are driving, your engine will stop running, and you will not be able to start your car until the timing belt is fixed. This can be a safety concern if it occurs while you are on the highway at top speed. To prevent this, it is important to change the timing belt before it gets to this stage.

How Often Should You Replace Your Lexus’ Timing Belt?

The timing belt of Lexus models is usually expected to be replaced around 60,000 to 100,000 miles of usage. But, the above-mentioned interval is a general rule, and it may vary according to the model and year of your vehicle. Check your owner’s manual or speak to your mechanic to find out the right time to change your Lexus’s timing belt.

Why Is It Important to Replace the Timing Belt?

It is very important to maintain the timing belt because if it breaks, it can severely damage your engine. When the timing belt breaks, the pistons, and the valves strike each other, bending the valves and the internal parts of the engine. This is a costly repair that can be easily prevented through routine servicing of the vehicle.
