What does adjusting cam timing do?
Advancing or retarding a camshaft’s timing from its original “zero” position causes the valve events to happen either earlier or later in the engine’s cycle. A camshaft that is advanced four degrees will cause each opening and closing event to occur four degrees of rotation sooner than before.
How tight should a cam belt be?

When do you check the camshaft timing belt?
The tension of the toothed belt that drives an overhead camshaft must be checked at the intervals set by the servicing routine laid down in the car handbook.

Loosen the tensioner enough so that it will be able to have a light contact with the timing belt. Check to see whether the timing belt is following its proper course. The timing marks on the belt should be aligned with the timing marks on the cam, crank and sprockets. If not, refer to the owner’s manual for the correct course.
What does the timing belt on a car do?

Though the mechanism itself is rudimentary, its function is so critical that you may need the help of a professional before you decide to adjust a timing belt.
How can I get the timing belt on the right course?
Compare the timing marks to make sure that the timing belt is on the right course. Look for timing marks on the crank, the cam and the sprockets. Make sure that they are all aligned evenly. Turn your engine manually by using a wrench to manipulate the crankshaft pulley.
