Hi my name is Brandon I am mechanical n electrical engineering technician and 4 generation mechanic its a blessing by God! But tell you little bout what I do I am not a mechanic I am the man they call when reg... mechanics cant fix it and I need more information to be right on the money whats a bout the altn.... sounds like bushIng are aad
Brandon, Mechanical n electrical engineering technician Email address is ([email protected]) I will get back to you asap soon I can Thanks God bless you
I can't say for sure but it could be the tensioner pully. I don't think you should be able to move it side to side. That would indicate that the bearing is worn.
Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....
Stop!
One of your pulleys is seizing. Most likely the a/c compressor or the tensioner (idler pulley).
Use a helper.... turn OFF a/c and have someone start the car. Observe the pulleys and see if the center one quits turning or is the source of the noise.
If can't determine and no noise, turn ON A/C and observe.
You will find it, but stay out of the line-of-fire if the belt breaks... it will be slingshot out of the engine compartment!!
Could be your belt tensioner is worn out and needs replacing, common for a 10 year old vehicle. Is it a loud squeeling noise? if so then it's the belt slipping and rubber on metal pullys is a loud screeching noise
Your drive belt tension may be set too loose or the belt itself is going bad. If you have a spring loaded tensioner, that may have weakened as well. Bottom line is that when belt is not tight enough, the normal load from the compressor added to the extra load on the pump when turning causes the belt to slip (making noise) Eventually, it may begin making noise when started as the alternator demands more power in order to work (you likely have heard cars with this problem in parking lots...loud screech right after starting) Wish I remembered which method they use to restore tension on yours butyou can easily get that info in any inexpensive manual (they may even allow you just to browse it without buying)
your timing marks must be off for the car not to idle. the timing belt is too tight, that is where the noise is coming from. rule of thumb is you should be able to twist the timing belt to just under 90 degrees on the longest section after the tensioner has tensioned and nut on pully it tightened. tensioners usually tension more than they need to.
Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.
