The service interval for a timing belt replacement on an Acura TL is either 7 years or 105,000 miles. If a vehicle is due for a replacement, Acura owners should change their car's timing belt to avoid costly repairs.
A timing belt, which is lined with teeth or grooves, is driven by the crankshaft. The camshaft of an engine works in tandem with the crankshaft to control the movement of valves. If the timing belt breaks or fails, the valves stay open instead of closing. As a result, the valves are hit by the pistons and the engine is seriously damaged.
