Everyone has heard the urban legend of a timing belt breaking… the stories are terrifying and repairs are exorbitantly expensive. But what exactly is a timing belt? And how do you maintain it?
A timing belt (or a timing chain on some cars) is the part in your engine that synchronises the rotation of the crankshaft that drives the wheels, with the movement of the engine valves, which provide the power. The timing belt makes sure that the valves open and close at the right time to ensure the car runs smoothly and has the correct airflow. It effectively helps the car to ‘breathe’; breathing clean air in and exhaust fumes out (or used air).
It’s what keeps everything moving together in sync, it’s a reasonably simple part in itself (just a rubber belt or a chain), but does an incredibly complex and vital job. Without this critical part, the engine’s operation will not be timed properly. If an engine is not timed properly it will misfire, resulting in some severe banging noises, possibly sending pistons flying out of their cylinders and completely bringing the car to a stop – maybe even to never start again!
In short, it causes a lot of damage. If the engine (as a whole) is not moving in the right way, at the same time, it can lead to disaster. Damage can include bent valves, piston and cylinder wall damage, and damage to the cylinder head. Any one of these could stop your car running. And they are VERY expensive to fix, as fixing means completely taking the engine apart and reconditioning the whole thing, from the core out.
It mostly depends on the make and model of your vehicle or the mechanic you use. Autoguru states the average timing belt replacement costs start at $500 and can reach well over $1000. CarSales says that labour costs alone can be upwards of $1,200 (8 hours to replace at $150 per hour). And that’s without parts! Also, most of the time, your water pump will be changed as well, which adds to the bill.
Keep in mind that dealerships can often be more expensive than your local mechanic, so make sure you get a second opinion. It’s also highly advised to make sure that when your timing belt is replaced, your vehicle service log book is updated and you keep the receipts for parts and work completed. This can impact the value of your vehicle if or when you come to sell it.
It’s worth mentioning that if it’s too late, and the timing belt has already broken, it might be the end for your car. If the aforementioned bent pistons or blown cylinder head was to occur, you’re looking at replacing the engine. As you can image, this is not cheap, no matter the model of car you drive.
Unfortunately, you won’t know when your timing belt is wearing, as you can’t actually see it. If you don’t replace it after the recommended period, it may break without notice. Replacing a timing belt when the manufacture recommends it is essential.
Once again, it depends on the model and make of your vehicle. Some need changing at 40,000km, others don’t need changing until 150,000km.
The general industry consensus is 100,000km or five years. Past this, it’s time to chat to your mechanic about changing it.
Definitely! If you are trying to sell your vehicle and it is close to a timing belt change, no savvy buyer is going to pay you full price.
Your buyers know they HAVE to spend this money and they are going to negotiate the cost of the timing belt change off your price.
If your timing belt breaks, then the value of your vehicle will reduce even further. So make sure you replace your timing belt to maintain the value of your vehicle, and make sure it is recorded in your service history / you kept the receipts and invoices. Remember: if it’s not recorded, it didn’t happen!
