Are you wondering how to know when your Lexus has a failing timing belt? Come find out! The timing belt is a rubber belt that has teeth on it and its function is to ensure that the crankshaft and the camshaft in your engine rotates in harmony. This synchronization helps the engine valves open and close at the correct time so that fuel can be introduced into the combustion chamber.
If the timing belt is not working correctly, your engine will not even start, or even if it starts it will not run smoothly. As a Lexus owner, it is important to know that timing belts are not immortal, meaning they are bound to wear out over time. The belt may wear out, become stretched, or damaged and when this happens, it can lead to severe engine problems.
Symptoms of Timing Belt Problems
Engine Makes a Ticking Sound
The first sign of a timing belt problem is the presence of a ticking sound from the engine area. When the belt is worn out or when it is loose it will make a ticking sound while attempting to keep the engine timed. If you hear this noise, then it is time to have your timing belt inspected and/or replaced.
Engine Misfires
Another common sign that your timing belt may be on its way out is if your engine starts to knock. Engine misfires are caused by a timing belt that gets loose and the cylinders open and close when they are not supposed to. This can cause low fuel efficiency, rough running at idle, and even stalling of the engine. If you have misfiring in your Lexus then it is likely that the timing belt is faulty, and you should have it checked.
Difficulty Starting the Engine
Sometimes, Lexus cars may be difficult to start and this may be as a result of a faulty timing belt. If the belt has become worn out or has a broken tooth, the compression of the engine is lost and this makes it very hard to start. In the worst case, the engine will not start at all. If you are having this problem, it is advisable to have your timing belt inspected or replaced because a damaged timing belt can severely affect your car’s engine.
Unusual Vibrations or Shaking
If your Lexus engine starts to vibrate or shake, particularly when it is idle, then this may be the signal that your timing belt is worn or damaged. If you experience any unusual vibrations or shaking, it is wise to take your car for a timing belt inspection to avoid worsening the problem.
What to Do If You Suspect a Faulty Timing Belt
Timing Belt Inspection and Replacement
The first thing to do is to seek the services of a good Lexus mechanic who understands problems related to timing belts. They can inspect the belt and see if it is worn out and make necessary replacements. The recommended mileage to change the timing belts differs from one vehicle to another, but it ranges from 60,000 to 100,000 miles for Lexus models. Even if you do not have any problems with the belts, it is recommended to change them at the recommended interval to avoid sudden breakage of the belt.
Consider Replacing Other Components
It is recommended that when changing the belt, other related components like the water pump, the tensioner, and the pulleys should also be changed. These parts are known to interact with the timing belt and it is cheaper to replace them at the same time to avoid incurring many expenses in the future.
