The timing chain tension guide, sometimes also referred to as the slide rail, is a critical component of a car’s engine and keeps the timing chain taut and free of play. By keeping tension on the timing chain it ensures that the timing chain stays on the timing gears at all times. If for any reason there is excess play in the timing chain, it can jump off the timing gear and cause failure of the engine and even bend the valves. The single function of the timing chain tension guide is to alleviate any play in the timing chain.
The tension guide on a car is a robust part but it is suggested that when the timing chain is replaced, the timing chain tension guide be checked for signs of wear. If there are any indicators of wear, it can then be replaced at the same time as the new timing chain is fitted. Usually the timing chain is changed every four or five years, so spending a little extra money on replacing the timing chain tension guide is well worth it. If the servicing mechanic suggests that this component be replaced along with the timing chain, don’t hesitate to do so.
