look for any metal or plastic cover/protector for casing of parts/ moving parts or the radiator fan casing rattles are majorly caused by poor bolting of parts or cracked parts. . best to do this with a stick and to dip in the parts with caution and see if rattle disappears. hope this helps..
Ignition system is not correctly timed. Set Base Time. ..If correct advance 5 degree see if this improves.... higher octane gas.and fuel system cleaner.. carbon build up in valve train
If you have not performed any service, might be a good idea to replace the components that you have mentioned and check to see if the problems go away.
Obviously one of the pulleys is loose or the tensioner is faulty. I would check all of the pulleys before trying to put the belt back on. You should find a bad bearing or broken spring.
Could be the timing belt tensioner. They are known to make a rattling noise when worn and/or the belt has stretched....When is the last time you had the belt serviced? They should be replaced and pulleys inspected at 100,000 miles. Gates recommends 120,000 miles on their belts. Good luck, i hope this helps.
lots of parts, alternator, water pump, a/c compressor lower area . many of them are on the serpentine belt. the pulleys and tensioner can make rattles. you need to confirm which part has the rattle or vibration, use a stick or screw driver. touch one end on the part and the other near your temple...any noise/vibration coming through?
fiind which one it is. lower noise on the crank can also sound like its coming from up front and that's a deep rattle.
It sounds like you have a broken serpentine belt tensioner. The tensioner should always be tight, it is spring loaded and you would have had to release the tension on it to have put the new belt on.Depending on what engine that is in yours, this could be an easy fix or a hard fix. The tensioner on a 2.2L is made into a large plate bracket that is attached to the front on the engine and several other items have to come off to replace it.The tensioner on the 3.1L v6 is smaller and has one bolt that holds it on.Either one is available at the local auto parts store.
no it would not be the timing belt making a rattling noise it couldn possible be you heat shield around your break rotor it could be someting having to do with ur suspenion like a spring maybe what kind of rattling noise? or a regular heat shield but loose in that particular area
Sounds like the timing belt tensioner. I have that problem. Rattles at low rpm, goes away as you acceralerate. Looking to have timing belts changed and tensioners replaced.
