What does it men when there is a rattling noise from the timing belt ?

i had my timing belt changed a year ago when i bought the car (2000 hyundai accent) and now when you turn it on there is a rattling sound like when you put a playing card in the spokes of a bike and when the car is warmed up you dont hear it anymore. dont know what it is...took it to a mechanic and he said he thought it was rubbing up against the plastic by the belt....now my car has started to idle rough.....help please?

If your timing belt fails, your engine stops, OR can very likey be damaged. This isn't something to ignore. Your mechanic needs to look at where the noise is coming from. No they don't %26quot;just make that kind of noise%26quot;

sounds like your water pump or one of the idler pulleys is going out,this will change the timing back and forth making it run weird one minute then fine the next......they can make some pretty funny noises too when something is failing in that area
Probably inadequate tension on the timing belt. There's typically a %26quot;belt tensioner%26quot; on the timing belt much like the one on a serpentine belt that runs your A/C and alternator/water pump/ect.



I'd check the timing belt cover (plastic housing) first to make sure it isn't rubbing the timing belt making all of this noise.



Good Luck!!
have the water pump checked



if the garages you have been too have both said they think its the timing belt or timing belt cover then they could well be right.



the timing belt commonly also runs the water pump, it may be that the bearing is failing or that the timing belt tensioner or idle pullies are failing.



if your car has not had the cam belt replaced get it done! its far cheaper to have to replaced now (and water pump at same time) than if one of the components fails. if a tensioner, idler or water pump fail they usually take the cam belt with them resulting in bent valves and a pretty big bill.

if the rattling eventually turns into a shaky engine after a couple of days, you are in need of a new harmonic balancer. This happens to be a very neccessary part of your engine that prevents it from shattering itself to pieces. 300 dollars is all it took to get a new one for my 93 century installed.
