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 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.
Land Rover is a luxury car brand that specialises in 4-wheel-drive vehicles.
Regarded as a British icon, the company came into effect in 1978, but previous versions were built as part of the Rover Company, dating back as early as 1947.
It is currently part of Jaguar Land Rover; owned by India’s Tata Motors since its acquisition in 2008.
How popular is Land Rover in the United Kingdom?
The number of Land Rovers on the roads continues to grow. This could be due to a rise in popularity or their indestructible nature and go anywhere, handle anything design and build.
There are around 940k on the UK roads today—and not just on the roads—they’re authentic working vehicles chosen by the majority as their commercial off-roader of choice.
Luxury executive vehicles built for getting dirty
The once army-style paint schemes and boxy vehicles of yesteryear have long-since been replaced by the modern Land Rover. These cars offer genuine luxury interiors, advanced media and drive control technology, and look every inch the part working on a farm, climbing through forestry or attending a charity event at Sandringham or Kensington.
Range Rover: the opulent end of the Land Rover range
The ultimate Range Rover starts with a price tag of £83k, and for that you’ll get a car with class-leading features, excellent components and incredible off-road performance. It’s a first-class travel experience with tomorrow’s technology built in. Every element has been scrupulously designed—and it shows.
Land Rover’s reliability and reputation
Land Rover shamefully ranked 30th out of 30 car brands in the What Car? Reliability Survey in 2018. For an off-roader designed to go anywhere, you’d expect it to be indestructible, but it scored only 76.5% reliability from its drivers taking part in the survey.
