Why should it be renewed:

Replacing the timing chain tensioner is advisable if there are signs of wear, looseness or noise in the timing chain area. A defective or worn tensioner can lead to insufficient chain tension, which can cause malfunctions in the valve train and, in the worst case, engine damage.
