Seat timing belt replacement

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.

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 after 4 years, or 6, or after driving 40,000 or 100,000 miles. 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.

Seat

Seat S.A. is a Spanish automobile manufacturer, founded over 65 years ago in 1950.

In 1986, the German Volkswagen Group bought Seat from the Spanish government to become the owner and operator of this established marque.

How popular is Seat in the United Kingdom?

Since the VW takeover, the number of Seat cars on the roads in the UK has grown steadily to over 500k.

Marketing similar cars to different markets

Although the structure and engineering behind all of the Volkswagen Group’s cars are closely related, based on very similar systems and practices, VW has aimed Seat at a market that offers something a bit different to Audi and VW.

Seat: Affordable, youthful versions of established models

Given that the brands under the VW umbrella (not forgetting Skoda too) all carry similar architecture, what sets the Seat models apart from their counterparts is their character, price-point and their ability to deliver slightly sportier handling due to their tuning. When you think of Seat, you think fun. VW: solid. Skoda: value. And Audi is for the executive.

So despite all being very similar machines under the hood, VW has created each of them to sit in quite different marketplaces. The Leon, for example, will appeal to a different type of driver to the Octavia or the Golf (and the Audi A3) despite being almost the same car. The same goes for the Ibiza, the Arona and the rest of the models in the Seat range.

Seat’s reliability and reputation

Seat ranked 10th place out of 30 car brands in the What Car? Reliability Survey in 2018.

Pitted against the other makes under the VW umbrella, it was Skoda who ranked highest in 7th place, with VW and Audi performing less admirably at 17th and 20th respectively.
