The timing belt is the most integral unit of your Subaru Outback engine. Without this belt, it is almost impossible for the engine to show its full potential. This is because timing belts play an important role in helping the engine work perfectly by combining its camshaft to the crankshaft, and not only this, the timing belt is also responsible for moving the valves and pistons of the car without any hassle.
This means that if anything happens to the belt, then the engine of Subaru is also going to give up soon. This is why it is always recommended by the manufacturer of Subaru to keep maintaining and servicing the timing belts as they can cause you a lot of trouble if you left them on their own.
However, even if you have been maintaining your timing belt, but still it is giving you a hard time, then your Subaru timing belt may have just finished its lifespan. Subaru Timing belt cost isn’t so high. We highly recommend you to change as you find some bad belt signs.
Life Expectancy of Subaru Timing Belt
When it comes to the life expectancy of a timing belt, you can never be sure of how long it will last. Though the estimated life expectancy of timing belts says that an average timing belt can last for almost 60,000 to 100,000 miles, however, some timing belts can even last as much longer as 200,000 miles. Whereas, in most cases, timing belts start giving problems before even completing 50, 000 miles.
So basically, the life expectancy of timing belts depends upon the manufacture who has created it. Timing belts created by different manufacturers vary in their expected lifetime. As for Subaru Outback, Subaru has claimed that the lifespan of their timing belts lies between 60,000 to 90,000 mileages that is equal to 7 to 9 years. This is not the case that you replace the belt after it’s broken. The owner must know the bad timing belt symptoms and visit the mechanic earliest possible.
However, for the last 10 years, most of the Subaru Outback’s newest models have been observed with lots of problems regarding their engine, especially with the timing belts. Many people who possess Subaru Outback’s 2008, 20011, and 20015 models have a complaint that their timing belts have given up before the estimated life expectancy and couldn’t even make 60,000 miles. It may be for different reasons that can be observed or inspected by a mechanic. For some of the owners, it reached only 70,000 miles. So you can expect your Subaru Outback’s timing belts to last for almost 80,000 miles. But if you have its other models, there is a chance that it can even go further.
Factors Decreasing the Lifetime of Subaru Timing Belt
Various factors are responsible for decreasing the life expectancy of the Subaru timing belt. However, the two discussed below are the major causes of timing belt failure:
Hydroplaning: hydroplaning is the biggest reason for timing belt damage. When the water between pulleys and belts cannot disperse away, it starts to aquaplane between them, thus reducing the power of the timing belt.
Oil shortage: if the timing belt has not been oiled for a while, the belt becomes dry, and as result friction starts producing between the belt and pulleys, and eventually it leads to breakage or tearing of the belt.
