change the timing belt, plus kit if needed.To fix the timing belt the mechanic has to: All vehicle types are different, but allow at least 3 to 8 hours for this service, all going well. You won’t want to hang around and wait while they do this service. Timing belts/chains can deteriorate and/or stretch over time. If you only use your car now and again and don’t do many kilometres, you will still need to have the belt/chain replaced based on the age of the vehicle. In modern engines manufacturers recommend replacing the timing belt from between every 40,000 – 150,000 kilometres, depending on the engine. While this may have been the case 20 years ago, nowadays you need to do your homework as every make, model and engine has different requirements. Some old school mechanics may tell you to replace the timing belt every 100,000 km. A timing belt has in recent history been the more commonly used part, but car makers are using a timing chain more often these days, as they find them to be more durable than belts. The belt or chain synchronises the crankshaft’s rotation with the engine valves, allowing them to open and close at the correct times during the air intake and exhaust stroke.īefore moving on, we should tell you that while the predominant part used is a timing belt, your car engine could instead use a timing chain.Ī timing belt is usually a toothed belt, and a timing chain is a roller chain. Unless you have gears directly driving your camshaft, as part of an internal combustion engine you will have either a timing belt or timing chain performing that task. So the cost of attending to the timing belt is well worth it in the long run. If you avoid doing this service and the belt or chain stretches, deteriorates, or breaks, it will more than likely cost you an engine without any warning. Which is what you might well be doing in the future if you don’t replace the timing belt when recommended! ![]() Have you just received a quote for a car service and wondered why you will have to pull out the plastic to pay for it? It’s probably an indication that the service you’re having done includes the replacement of your timing belt, or timing chain (different names, but they do the same job… more on that later).Ī timing belt is one of the more expensive and intensive services your vehicle will go through, second only to the non-service task of replacing or reconditioning the engine. To avoid you coming to a halt in the middle of the road, because of a banging, crash of pistons and valves fighting with each other, let’s investigate what the timing belt is, what it does, and why it costs so much to replace or repair. And often the extra expense is all down to a crucial part of the engine called the timing belt. Somewhere around each 40,000 to 150,000 kilometres – it varies from model to model – servicing your car gets to be a big pain in the wallet.
