What Causes A Timing Chain To Break?

Can you start a car without a timing belt?

For starters, your car won’t run without a timing belt.

Your timing belt rotates your car’s engine’s cam and crankshaft. This allows each cylinder to fire at the right time. If this timing is off, the engine will not run smoothly if it is even able to run at all.
