What does a timing belt do?

The timing belt, or cambelt, is a vital engine component with a key role to play in keeping your motor running smoothly. It ensures the top and bottom halves of your engine rotate precisely in time with each other.

Essentially, this ribbed rubber belt with teeth synchronises the crankshaft and camshaft’s rotation. It controls the sequencing and timing of the opening and closing of the valves on the cylinders in your engine to provide the right combustion.

Camshafts, made up of the main journals, the lobes (or bulges) and the ends, control the valves in the cylinder head. A rocker head takes the spinning motion of an overhead camshaft and turns it into the movement that opens and closes the valves.

Timing chains essentially perform the same function as cambelts but may be slightly noisier. The chains generally last as long as the vehicle (and generally require less frequent replacing), although the plastic guides they run over may not.

Volkswagen

Volkswagen (often shortened to VW) is a German automobile manufacturer founded in 1937 by the German Labour Front, a Nazi labour union.

Volkswagen is the flagship marque of the Volkswagen Group, who in turn is majority owned by Porsche. They own and operate a vast number of cars under other brand names—at the time of writing, they have 342 subsidiary companies.

How popular is Volkswagen in the United Kingdom?

Possibly its most well-known model of the current generation, the VW Golf, was the 2nd best selling car of 2018, behind the Ford Fiesta, which consistently takes the top spot year after year.

The Golf’s 64k registrations in 2018 added to the vast tally of 3.4million Volkswagen cars on the road today.

High quality, highly rated, appropriately priced cars

VW cars achieve consistently strong reviews and are highly respected by critics and drivers alike. They are renowned for investing more money into research and development than almost any other marque and distributing their wealth of motoring knowledge across the many partner brands under the VW Group umbrella.

The Volkswagen Beetle: The ‘people’s car’

A classic of its time, originally named the Volkswagen Type 1, it soon became nicknamed the Beetle due to its unique shape, and subsequently the bug. The unique looking car was designed by Ferdinand Porsche for Adolf Hitler, who wanted a cheap and simple mass-produced car to travel around his country’s new road network.

The new model Beetle, originally launched to celebrate the original classic in 1997, and with an updated successor in 2011, was designed around the VW Jetta platform sharing much of its build with the Jetta and Golf. VW announced in 2018 that the Beetle would finally be removed from production in July 2019.

How often should a timing belt need replacing?

There’s no ‘one size fits all’ approach for how often to replace yours—a lot depends on your motor’s age and condition.

There’s also huge variation between manufacturers and different engines. So you might need a new belt every 3 to 5 years, or after 40,000 or 60,000 miles, whichever comes first. Consult your car’s manual—most manufacturers’ recommendations are based on time passed or miles driven, depending on which elapses first.

However, we’d always suggest treating these recommendations as a maximum, and erring on the side of caution.

The law, vehicle regulations, and your MOT

The timing belt will not be examined at your car’s MOT, but the associated issues of running a car with a faulty timing belt can lead to severe engine damage, which can.

What happens when we replace your timing belt?

• Our efficient and fully qualified mechanics will disassemble the parts of the engine to access the timing belt and proceed to examine the timing belt, the belt’s pulleys and tensioner.

• Wherever required your timing belt will be replaced and you’ll be advised of any other connected or associated problems arising from its malfunction.

• You will also be advised of any other parts that may need to be replaced for the best operation and health of your vehicle.

• Once the timing belt has been replaced, our mechanics will test your car thoroughly to ensure the correct running of the new part and make any adjustments required for its premium operation.

What causes a timing belt to stop working correctly?

Like most car parts, your timing belt will wear out eventually due to cracking, snapping or tearing. Timing belts are also unpredictable, with few warning signs of damage. (Although starting issues and noise may offer clues.) Driving your car infrequently, oil leaks and temperature changes, among other factors, can all play their part.

Symptoms of a malfunctioning timing belt

You hear unusual noises coming from the engine

If a grinding or squeaking noise is being emitted from your engine, it could be a malfunctioning timing belt.

The car won’t start

If your timing belt has broken, this can cause problems with your engine that lead to the vehicle not starting.
