My garage says I should buy not only a new belt but also a complete timing belt “kit”, including the tensioner bearing, its mounting and its shaft (altogether nearly five times the cost of the belt itself).
Question: My car manual says I should change the timing belt every 100,000 km. My garage says I should buy not only a new belt but also a complete timing belt “kit”, including the tensioner bearing, its mounting and its shaft (altogether nearly five times the cost of the belt itself). Why is a tensioner bearing so much more expensive than other bearings of similar size, and is all this necessary in the first place? I have now done 120,000 km and there is no sign of anything wrong with the timing.
Answer: All manufacturers recommend a timing belt change (many at 100,000 km) as a purely “precautionary” measure.
