Shop BMW 525i Replacement Timing Belt Tensioner

The timing belt tensioner in a BMW 525i is part of a system that prevents the engine from destroying itself. The timing belt tensioner keeps the timing belt from behaving in ways that could lead to automotive havoc. If the timing belt tensioner fails while the BMW motor is running, it could cause the timing belt to allow valves and pistons to slam into each other. Any mechanic could find that difficult to restore to normalcy. Automobile experts advise changing the timing belt system, including the timing belt tensioner, about every 60,000 miles. That may seem a bit too cautious, but it's nothing compared to what it would take to slide in a new engine. One caution: Don't let coolants or motor oil touch the timing belt. That's disaster not possible for a timing belt tensioner to overcome. We know what it takes at Parts Geek.
