One of the pulleys is not turning. Could be AC, alternator, or one of the idler pulleys.Take a careful look with a good light. My bet is the idler pulley.

Loud rattle sound when Idling


I suggest you have your car checked as soon as possible - while a rattling exhaust isn't desperately urgent it could be the cat breaking up which might later restrict the flow of gases. Most importantly excessively loose timing belts or chains tend to make most noise when the engine is idling. If the noise is being caused by this delay could be very expensive.

My 2004 Prius has a rattling metallic sound on acceleration. It is coming from the top of the engine on the passenger side. Does anyone know what this can be?


Does the car make this sound when the car has just been turned off and engine is still hot? Lightly push the car back and forth while it's in park. Does it still make that sound?

I have a 1997 Saturn sl1. When you put the car in gear it makes a rattling sound. I thought it was the heat shield so I took it off because it was hanging by 1 bolt. That was not it. I replaced the top...


these cars are common for the automatic serpentine belt tensioner breaking down, causing an almost plastic like rattle. the fact that it gets worse in gear and with the A/C on confirms this suspicion. buy a quality brand name, such as a delco, or else you are asking for more problems. avoid the goodyear brand. good luck!

Hi, I was just driving home and my car was making


Yes, you apparently heard the belt as it came apart. You can look around the path of where you heard the noise and see if there is any obvious damage but usually, there are just a few marks unless a small wire or hose are in the path of the belt. good luck

2002 Saturn Vue V6 AWD sounds like an F1 car when i drive it. Very loud constant noise. Checked trans fluid and it was fine.


I have a 2002 saturn vue. Same thing..sounded like a jet engine ...loud humming as I accelerated . It got increasingly worse. It turned out to be the front wheel bearings. Replace them, now the noise is half as loud...have to do the rears also! 93,000 miles on it. Also, don't forget to replace the timing belt. It it goes too long and breaks, it will trash the engine...

2004 Ford Taurus V6 noise underhood appears to be belt


Sounds like a bad idler pulley,or belt tensioner. Most likely not water pump since the check engine light is not on. Altho it couold be the water pump and for some reason (bad sensor, burnt out light) the check engine isnt coming on. Either way it would be best to have it looked at.

Loud Screeching sound When Turning only on occassion.


it sounds like the power steering belt is loose. If it has a tensioner pulley the spring in it might be loosing it's tensile strength. While you are looking at the belt pay attention to the side that is against the pulley to see if it has alot of cracks. If it has I think 10 cracks per inch that is too much and needs to be replaced.

Engine noise


If it gets worse when turning the wheel at a stop, then it's the power steering pump. Could be the power steering fluid also. Check your belts for wear or damage. The idle pulley will make a constant noise, sometimes whining sometime screeching. To check idler pulley it is best to remove belts.

You have a loose belt on the A/C. On most new cars that is one big belt that drives everything on the car. If when you look at the belt on the grooved side, do you see cracks on the grooved part running across (from side to side) on the belt? if so, it is in bad need of a new belt. A new belt should stop the squealing noise. While you are replacing the belt also check the belt tensioner to ensure it is in good working order.
