Does a bad alternator make a clicking noise?

It requires a good deal of energy to crank the car’s motor, and if a battery is not replenishing its power properly due to a faulty alternator, it will become drained and ineffective. You will hear a clicking noise while attempting to start the car, and the engine will have difficulty turning over.

What does a bad timing belt sound like?

On the contrary, if the oil is too thin, it won’t provide proper lubrication as well as padding.

What happens if you advance timing too much?
