When Should You Replace Your Timing Belt?
Author: Toby Date Posted:4 September 2024
Maintaining your vehicle involves more than the occasional oil change or tyre rotation—some components require more attention than others, and the timing belt is one of them.
If you’re not familiar with what a timing belt does or why it’s so critical to your engine’s performance, you’re not alone. Many car owners don’t think about their belts and timing parts until it’s too late.
In this article, we’ll break down what a timing belt is, how to recognise when it’s time for a replacement, and why you can’t afford to ignore this vital part of your vehicle.
What is a Timing Belt?
A car has a lot of moving parts, and those parts need to move in harmony to operate smoothly. A timing belt, often made with durable rubber, controls the timing of your vehicle’s internal combustion engines.
It works to synchronise the rotation of the crankshaft and camshaft, ensuring that the engine’s valves open and close at the right times. Without this precise timing, the engine wouldn’t run smoothly—or at all.
So, what else do you need to know about timing belts? For starters, they’re not visible during routine engine inspections because they’re usually tucked away behind protective covers. This means that by the time you notice a problem, the belt might already be on its last legs. Because just like any other part, they wear out over time.
Which brings us to our next question. What happens when it breaks? And when should a timing belt be replaced?
How to Spot a Damaged Timing Belt
Since you can’t easily check the timing belt yourself, knowing the symptoms of a failing belt in a car is crucial. Here are some signs that could indicate it’s time for a timing belt replacement:
Your engine is misfiring
Caused by incorrect timing of the engine’s valves, a worn timing belt can cause the engine to misfire as the belt could slip on the camshaft. If you hear any repetitive ticking or clicking sounds from the inside of an engine, it could be a sign that your timing belt is damaged.
Your engine struggles to crank and start
When you’ve got a worn-out timing belt, you’re going to notice that it’s far slower to start your car than it used to be. This is especially true if the belt has slipped or broken.
You noticed visible wear and tear
If you’re able to inspect the timing belt, look for signs of fraying, cracking, or missing teeth. Any of these issues mean it’s time to replace the belt.
There are oil leaks and smoke
An oil leak near the timing belt cover could indicate that the belt is damaged, potentially due to heat and friction. Also, if you notice a burnt rubber smell coming from your engine, it could be the timing belt wearing down.
How Often Should a Timing Belt Be Replaced?
The good news is that with advancements in technology, timing belts don’t need to be replaced as frequently as they used to. However, this doesn’t mean you should put it off for later.
How long do timing belts really last? While car usage is also a factor to consider, seven years is the maximum life of the timing belt recommended by most manufacturers.
But experts recommend replacing the timing belt every between every 60,000 and 100,000 kms. While the exact interval depends on your vehicle’s make and model, a good rule of thumb is to start thinking about a replacement around the 60,000-km mark, and definitely before hitting 100,000 km.
Remember, timing belts are relatively inexpensive to replace compared to the damage a broken belt can cause. Neglecting it could mean thousands of dollars in repair costs if your engine is damaged.
If you’re unsure when your timing belt was last replaced, check your vehicle’s service records or consult your mechanic. It’s better to replace the belt a little earlier than to risk further damage to your vehicle. Or worse, the valves and rods can push through the engine cover, completely ruining the engine.
How Much Does a Timing Belt Replacement Cost?
In Australia, the cost of a timing belt replacement typically ranges from $500 to $1,200, with some luxury vehicles potentially exceeding this range. This cost includes the timing belt itself, tensioners, and labour. For luxury or performance vehicles, you can expect higher costs due to the complexity of the engine design or the use of premium parts.
When you receive a quote for a timing belt replacement, ensure it includes all necessary parts and the labour involved in the installation. While the upfront expense may seem significant, it's important to consider the potential cost of not replacing your timing belt on time. A broken timing belt can cause severe engine damage, leading to repair bills that cost more than a timely replacement.
In the long run, investing in a timing belt replacement is a smart way to protect your engine and avoid unexpected repair costs.
