What does the timing belt do for your engine?

Being a part of the internal combustion engines, the timing belt is in charge of synchronizing the functions of the engines. It is in charge of the crankshaft and camshaft’s rotation, and allows gas and air in and out by controlling the opening and closing of many valves of the engine, thereby allowing the fuel to ignite in the combustion chamber. During the explosion, the valves are there to stress the pistons down.

To ensure the whole process take place properly, the valves should open and close at the right time. Besides, the valves and the pistons should be in the right position. For each cylinder, the valves will open at a different time.

When the timing belt breaks, the valves will fail to open at the right time, and cause damage to the engine by hitting larger pistons.

When should you change your timing belt?

It’s extremely hard to spot an imminent death of a timing belt; therefore, just bear in mind that the milestone for each timing belt change should be around 60k to 100k miles, which is recommended by most auto brand’s manuals and mechanics as well.
