Why the interval matters
A timing belt usually gives no warning before it breaks. On many engines, called interference engines, a broken belt lets the pistons strike the valves. Replacing the belt on schedule costs far less than repairing that damage.
Belt or chain?
Not every engine has a timing belt. Many use a timing chain, which normally lasts much longer. We will look up your engine and tell you which it has and whether anything is due.
What is replaced with the belt
The belt, tensioner and idler pulleys are replaced together. Where the water pump is driven by the timing belt, it makes sense to replace it at the same time, since the labor overlaps. We also check the cam and crank seals for leaks.
