From 2011 until the present all models of the Hyundai Elantra have actually used a timing chain instead of a timing belt. If you have a newer model of a Hyundai Elantra you likely don't need to worry about changing your timing belt. That could result in the valves not being open at the correct time, or the combustion reaction occurring when the pistons are in the incorrect place.ĭo Hyundai Elantras Have Problems with Their Timing Belts? If those notches were to wear down, or the belt were to get stretched out, it would lose its grip and not be able to rotate between the camshaft and the crankshaft properly. Unlike your serpentine belt which is smooth, the timing belt has notches on the inside which help it grip the ends of the camshaft and a crankshaft while it rotates. The timing belt itself is just a rubber composite belt. All of these things need to happen at precisely the right time, or your engine will perform poorly, or not at all. As the camshaft spins, it opens the valves at the top of the cylinders to allow the piston to pass through unencumbered. The other end connects to the camshaft so that when the crankshaft rotates, the camshaft will rotate with it. The end of the crankshaft has the timing belt looped around it.
In order for everything to happen at the same time, the crankshaft rotates, pushing those pistons up into the cylinders. It happens many hundreds of times per minute in order to create the power needed to move your Elantra forward. This happens in each cylinder of your engine whether it's four, six, eight or whatever. The spark plug ignites this fuel and air mixture which creates an explosion that in turn forces the piston back down through the cylinder. The way a modern combustion engine works is that pistons rise through the cylinders of your engine and a mixture of fuel and air is injected in precise amounts into the combustion chamber. In order for your Hyundai Elantra to function properly the timing of the engine has to be precise down to the fraction of a second. What Does a Timing Belt Do? – Timing Belt Replacement Cost for a Hyundai Elantra For that reason, you want to make sure you're getting your timing belt replaced when you need to have it done. The damage that is caused to the cylinder heads, the pistons, the valves and the rest of your engine could end up costing you as much as $4,000 or more to get fixed. The moment it breaks your engine will stop working. You won't be able to pull over to the side of the road like you would if your car just started overheating. When a timing belt breaks there is no warning time, and no chance for you to react. When that happens, it can cause serious damage to your engine and could potentially cause an accident if you are driving at speed down the highway, for instance. The longer you put off replacing it, the more likely it is going to break while you're driving. It's possible that a timing belt will last for 200,000 miles or more, but it's never recommended to try to get it to go that far. If you don't replace your timing belt according to the schedule that Hyundai has developed for it, you're putting your engine at serious risk. If you've never done something like this before, it's probably best to leave it up to a professional. It's possible you could do this repair on your own at home, but you really need to be comfortable working on the engine as this is not a beginning repair job by any means. You're going to be paying for your mechanic's time to do so. The reason there is such a price difference between the part and the labour is that it takes quite a bit of time and effort to get into where the timing belt is located in your engine. Just make sure you're getting the right one. If you're just in the market for the belt on its own, you can head to a site like and pick up a new one for between $20 and $200.
