if timing belt gonna break, will it make noise before it break? i got this loud cracking noise from the left side of my engine. it is right between the power steering and the cam gear cover. any suggestion?

 

id check just to make sure...unless you wanna replace your engine

 

Maybe it's loose & slapping on the inside of the plastic cover. Take off the cover & see. NOW before it breaks.

If you see ANY kind of hairline cracks at the teeth of the belt, replace it. Turn the engine so you can inspect the belt all the way around.

How many miles on the belt? Anywhere near 90k just replace it anyway.

 

it is a used car. i bought it with 160000 miles. don't know the guy replace it or not. if they change it at 75000-90000, i should replace it now. right?

 

If they changed it at 90k you should replace it before 180k.

If they changed it at 70k you should replace it NOW.

If they didn't replace it, you're already REALLY, REALLY lucky.

It's only a few bolts to take off the covers. If I were you I'd take a good look at the belt right now.
