5 Indicators That a Timing Belt is Failing

INTRODUCTION

There are some warning signs that can assist you in determining when you need a new timing belt, but it is crucial to remember that prevention is the key to optimal car maintenance, as there are no specific clues to prove a worn belt that is on the verge of snapping.

The five key signs to be aware of are listed below to help you determine if it's time to check and replace your timing belt.

1. Misfires in The Engine

Timing belts operate both the camshaft and the crankshaft via a system of pulleys. The teeth used for this are designed to grip and move smoothly, but if the timing belt begins to wear out, it may produce a repetitive clicking or ticking sound from inside the engine.

2. After Starting the Vehicle's Engine, There is Smoke

Belt wear and stretching harm the catalyst because the fuel is not completely burned in the chambers due to an incorrect mixture fuel composition. This means that any remaining fuel is directed to the exhaust system. If you hear a clicking noise when starting the engine and see black smoke coming from the exhaust pipe, this indicates an incorrect fuel composition, which could be caused by a variety of factors, including timing belt damage.

3. Difficulty in Getting Started

Because it is connected to the pulleys that drive the crankshaft, a worn timing belt will affect the starting speed of your engine. The belt can eventually slip on the camshaft drive, causing the engine cylinder to open and close at the incorrect time.

The stretching or wear of the timing belt causes it to skip one or more teeth, causing the engine ignition to be lengthened.

Additionally, as previously stated, belt jumps or slips cause engine desynchronization.

4. The Appearance of The Belt

If we are inspecting our vehicle or going to the garage, the first sign that the belt is worn is its appearance. There are small cracks visible throughout the piece. The internal threads of the cracks can be seen when the cracks are enlarged. Another sign is the separation of small pieces or fragments of belt material, which will eventually fall inside the engine.

5. Voltage Drop

High elongation is another sign of advanced belt wear.

When this happens, there is a loss of tension, which reduces the belt's deflection force. This will result in belt slipping or, worse, belt dropping during engine operation.

Belt slippage or skipping causes the engine to be out of sync, which can result in a piston/cam collision and catastrophic engine failure.
