The timing belt is placed in front of the engine of your car. It is constructed of a durable rubber substance with nylon-reinforced cords. The timing belt's lifespan can be extended in this manner.

The timing belt is put under a lot of stress when moving within the engine, and as a result, it wears out rapidly. As a result, the timing belt will need to be replaced on a regular basis as indicated by the car manufacturer.
You
may do a lot of expensive damage to your engine if you let your timing belt
wear out and don't replace it on time. Choose a garage with competent
vehicle technicians when looking for car garages in
Reading to book your car in for timing belt replacement online, as one
tiny error can cause catastrophic engine damage.
What is the Function of a Timing Belt?
Your
car's engine runs on timing belts. They link the crankshaft of your engine to
the camshaft and are responsible for managing the pistons and valves in your
car. The timing belt is a strengthened rubber band with teeth or notches on the
inner side that accurately synchronises the opening and shutting of the engine's
valves, to put it simply.
The
crankshaft turns, which sets the timing belt in action. The timing belt then
spins the camshaft, allowing the pistons to rise and fall by opening and
closing each valve. Four separate stages exist in a four-stroke engine, for
example:
·
Intake
·
Compression
·
Combustion
·
Exhaust
Air
and fuel are sucked into the cylinders during the intake phase. Intake valves
open and exhaust valves close during this period.
The
air and fuel are combined, compressed, and ignited by spark plugs during the
compression and combustion stages. All of the valves are closed during these
two periods.
The
exhaust phase is the final step, in which the exhaust valve expels any residual
air or fuel. During this time, the intake valves are closed, and the exhaust
valves are open. The timing belt is in charge of all valves opening and
closing, as well as piston timing, during each phase. The timing belt
guarantees that each action is carried out in the correct order.
Symptoms of a Malfunctioning Timing Belt
The
following symptoms may arise if your timing belt is damaged or worn out. If you
notice any of these symptoms, search for garages in Reading
online and have a qualified car technician or mechanic evaluate the timing
belt and, if required, replace it:
1. Rough Engine Idling -
Timing belt teeth grab gears as they spin various engine parts and components,
causing rough engine idling. If these teeth begin to flake off or become
brittle, the timing belt will begin to move away from the gears. The teeth will
then fall into the gears, generating an engine shock. Worst of all, the engine
would stall due to the incorrect camshaft timing. Check MOT status
and have this issue addressed as this could possibly lead to an emissions
test failure on a MOT test.
2. Engine Misfire - If the
timing belt is worn out, the engine's fire rate may be compromised. If the
timing belt separates from the gears and lands on the camshaft, one of the
cylinders will open and close prematurely. If this happens, an engine misfire
may develop, necessitating the replacement of the belt as soon as possible. The
engine may be irreversibly damaged if the belt is not replaced promptly.
3. Smoke from the Engine - It
might be difficult to know if the large volumes of smoke coming from your
exhaust are truly normal steam or water vapour when it's chilly outdoors.
However, if you see unusually large amounts of smoke, especially in the cold,
it might be a timing belt issue. A defective timing belt might be the cause if
you check MOT history
and your vehicle has previously failed an emissions test.Exhaust is released
through two openings at the top of each cylinder, which also enable air to
enter. The rotation of the camshaft and the movement of the cylinders cause
these openings to open and close. Your timing belt will become unsynchronized
as it wears down, enabling exhaust and air to escape at inconvenient times. As
a result, your exhaust system will be filled with smoke.
4. Oil Pressure Drop - The timing
belt rotates the camshaft's gears. If the timing of the belt is improper, the
camshaft may be snapped off. Some of these shards may fall into the vehicle's
oil pan, causing the engine's bottom oil pressure to drop. After then, the
engine would entirely fail. The engine must be entirely rebuilt in order to get
back on track.
5. Damaged pistons or valves
- Having the timing belt partially or completely broken is the most serious
symptom. If this is the situation, the crankshaft will begin to move independently
of the camshaft. The piston will make contact with the valves when the valves
open. The valves may flex, and the piston may be injured as a result of this.
Turn off your engine as soon as you detect this symptom if you want to
safeguard it from further damage. It's possible that you'll be able to avert
serious engine damage by doing so.
6. Check Engine
Light Turns On - Ticking or rattling noises, poor engine performance,
and overheating are all symptoms of a loose or worn timing belt, which
frequently results in the check engine light turning on. The engine will not
start if the timing belt breaks, and certain engines will suffer internal
damage if the timing belt breaks.
When Should You Replace Your Timing Belt?
A
timing belt is one of the car parts that must be replaced in accordance
with the manufacturer's instructions. This usually happens every 75,000 to
100,000 miles on average. The specific itinerary for your car may be found in
the owner's handbook.
Timing
belt replacement is not something that can be put off forever. The belt will
eventually break, causing the engine to be damaged to the tune of hundreds of
pounds. It's simply not worth taking the chance.
