A cambelt, also known as a timing belt, may seem like an\ninsignificant part but it is a crucial component of your engines running\nequipment.<\/p>\n\n\n\n

The cambelt is usually made up of rubber and synthetic mix to increase its durability. It has grooves (teeth) on one side which help to enhance the grip on the heads of different shafts within the engine. Without these grooves, the cambelt could slide off at any time.<\/p>\n\n\n\n

Is a cambelt the same thing as a timing belt?<\/span><\/strong><\/h2>\n\n\n\n

You might hear the terms “cambelt” and “timing belt” thrown around, and you’d be right to wonder if they’re the same thing. The answer is yes! Both terms refer to the same essential engine component \u2013 a toothed belt that synchronises the crankshaft and camshaft in your car. This keeps the opening and closing of engine valves in perfect time with the piston movement, ensuring smooth operation.<\/p>\n\n\n\n

Historically, engines relied on timing chains, made of metal links similar to a bicycle chain. While durable, these chains added noise and required constant lubrication. The shift to timing belts, composed of reinforced rubber, offered a quieter and more efficient solution. Though belts need replacing periodically due to wear, their overall benefits solidified their place as the dominant timing mechanism in modern engines.<\/p>\n\n\n\n

\"What<\/figure>
\n

What does a timing belt do?<\/span><\/strong><\/h2>\n\n\n\n

The timing belt synchronises the rotation of the crankshaft and camshaft to keep it timed. In essence, it keeps the bottom half of the engine (pistons and crankcase) in sync with the top half (valves and cylinder head).<\/p>\n\n\n\n

Do all cars have a cambelt?<\/span><\/strong><\/h2>\n\n\n\n

Not all vehicles have a cambelt, though the term “timing belt” and “cambelt” are sometimes used interchangeably. <\/p>\n\n\n\n

Many vehicles instead rely on a timing chain, which functions very similarly to a belt but is made of metal links rather than rubber. Both components keep the engine’s valves and pistons in sync, ensuring optimal performance.<\/p>\n\n\n\n

If you’re unsure whether your car has a belt or chain, you can consult your owner’s manual or consult a mechanic.<\/p>\n<\/div><\/div>\n\n\n\n

Do Electric Cars have cambelts?<\/span><\/strong><\/h2>\n\n\n\n

Electric cars don’t have cambelts as they don’t have combustion engines, instead relying on electric motors which have a much simpler design with fewer moving parts. This means electric vehicles have no need for cambelts and the maintenance that comes with them.<\/p>\n\n\n\n

When to change the timing belt?<\/span><\/strong><\/h2>\n\n\n\n

The cambelt is a consumable car part, which means it will\nneed replacing. The material wears over time which makes it more susceptible to\nbreaking. It also becomes more brittle and may become cracked or frayed as a\nresult.  The cambelt is also susceptible\nto stretching which can affect the timing and put it out of sync. <\/p>\n\n\n\n

So how do you know when to change your cambelt?\nUnfortunately, with so many variables, there is no one size fits all when it\ncomes to changing the timing belt.<\/p>\n\n\n\n

Most manufacturers suggest either a time or mileage-based change, whichever comes first. However, even the mileage or time suggested can vary massively between both manufacturers and types of engine. It is not unheard of for mileage change recommendations to vary from 40,000 to 100,000-miles or from four to six years.<\/p>\n\n\n\n

You should be able to find information regarding your car’s specific cambelt change schedule detailed in your car’s handbook. The figure stated should be treated as an absolute max.<\/p>\n\n\n\n

Signs your timing belt needs changing<\/strong><\/h2>\n\n\n\n

It can be quite difficult to detect the signs indicating your cambelt need changing, which is one of the reasons you should not ignore manufacturer guidelines or advice from a mechanic.<\/p>\n\n\n\n
