What is the difference between a serpentine belt and a timing belt on a 2001 Toyota celica gts?

Answer 1

The serpentine belt is the belt you see that rotates around your alternator and Power Steering pump and a/c etc. If this belt breaks you will just lose the accessories it runs The timing belt is under a cover at the front of your engine. It is connected to pulleys on the crankshaft and the camshaft and as it rotates it keeps the valves opening and closing at the right time. If this belt breaks, and if the engine you have is called an "interference" engine, the valves will come down and hit the pistons at the wrong time possibly punching holes in the top of the pistons and bending valve stems. serp belt runs alt power sreer and ac timing belt is internal and runs cam in time with crankshaft ( lets car run)
