Does the 2011 Subaru Impreza have a timing belt or chain?

The 2011 Subaru Impreza is equipped with a timing belt that is an important part of Your engine's firing. Belts direct the cooperation of the crankshaft and the camshaft to ensure pistons open and close at appropriate times. Most belts need replacing between 60,000-100,000 miles, and those numbers are affected by where and how You drive Your vehicle. Subaru suggests replacement at 105,000 miles. The repair is expensive, costing anywhere from $600 to over $1,200 for parts and many hours of labor. By default, chains are more durable and don't suffer from cracking or drying out like belts do, because they operate from inside rather than outside the engine. Signs the timing belt is deteriorating include a decrease in power, rough idle and engine noises.
