You may have a failed tension idler which the mechanic should have checked when replacing the serpentine belt.

SOURCE: Replacement of 06 toyota corolla

I own a 2006 Corolla and can give the following advice. Begin by purchasing a quality replacement belt. I highly recommend the Goodyear Gatorback serpentine belt due to it's quality and unique ribbing designed to eliminate the high pitched chirps and squeals which commonly occur with the original equipment belt on these cars. You will need a 3/8 breaker bar with a 19mm socket and a piece of pipe at least 18" long to slip over the end of the breaker bar to provide additional leverage. This will be used to remove the tension on the belt for removal and installation. You'll also need a metric socket set to aid in removal of the plastic cover that sits on top of the engine. Start the process by removing the plastic cover using a ratchet and 10mm socket on the two acorn head nuts near the front of the cover. Then remove the two plastic push-in fasteners at the rear of the cover by gently prying in an upward direction. Removal of this cover gives more room to help you work the new belt around the pulleys. Make a diagram of the pulleys and belt routing as a reference to help you when installing the new belt. Find the belt tensioner (it looks like an arm with a small piston-like device attached to one end and a smooth faced pulley on the other end.) You will see what looks like two hex shaped bolt heads cast into the metal of the tensioner arm. Place the breaker bar with 19mm socket onto the upper hex casting so that the breaker bar handle points straight up. Slip the pipe over the handle of the breaker bar and pull toward the front of the car. This will relieve the tension and allow you to remove the belt from the alternator pulley. Once the belt is free set the breaker bar aside and work the belt off all the pulleys. Installing the new belt can be a little challenging and will be extremely difficult if you start in the wrong place. Although the new belt goes over the alternator pulley last, it is in fact where you should begin the installation. You'll notice that the top path of the belt goes from a large pulley at the rear of the engine straight to the alternator pulley at the front of the engine. What you want to do is put the belt on the alternator pulley and then begin routing the lower path of the belt around all the pulleys and the pulley on the tensioner arm until it is around everything except the large pulley at the rear of the engine. Then take a piece of stiff wire and bend it into a hook on both ends so that you can gently remove the belt from the alternator pulley and use the wire hook to hold it in line with the other pulleys while allowing enough slack to work it over the last large pulley in the back. I hook mine to a convenient hose located in line with the pulleys just below the alternator. I found that the extension pipe was handy to help nudge the belt onto the lower ribbed pulleys because I couldn't get my hand into the narrow space. Once you have the belt routed and properly positioned on all the pulleys use the breaker bar and extension pipe to again relieve the tension allowing you to slip the last loop of the belt over the alternator pulley. Take a flashlight and carefully examine the belt routing to make sure it is properly positioned on all the pulleys, especially the ribbed ones. Improper installation will cause the belt to jump off and/or damage itself. Once you are satisfied with the belt installation you can replace the plastic cover on the engine. Start the engine as a final check that everything is working properly and enjoy your new quiet belt. This looks like a complicated procedure but will take less than one hour and those that are mechanically inclined should be able to get it done in 30 minutes or less. Hope this helps you.

1992 Pickup: loud squelling sound under hood when started...

Sounds like a loose belt.

There are a few things that can cause a belt to slip like that.

The belt could be not tightened all the way. If it uses a sepentine belt with a tensioner, the tensioner could be bad. If it is not a serpentine belt, then you will have multiple belts and the one that is making the noise can be loose. Use something to pry it tight and tighten down the bolts holding the component th belt goes to.

It can also be a bad pulley. Pulleys have bearings inside of them, at times the bearings will go out and make the pulley hard to turn. You can usually find this easily by taking the belt off and turning the pulley with your hand. If it is hard to turn or makes a grinding noise when is bad and needs to be replaced.

Old belts can also cause this along with a belt that is wet. There is a spray on Belt Dressing that helps get rid of noisy belts, but I consider that a bandaid to a bigger problem.

I had 2003 Toyota Camry 4 cylinder in for

While it is a possibility, having the tensioner lose tension seems more probable that it locking up as the mechanics have stated. You seem to know what you are talking about, so why not try throwing a wrench on it and turning it towards the serpentine belt? Then you can see for yourself if it has seized or not. It is the small pulley that doesn't seem to power anything like your AC compressor, alternator, fan, crank, powr streering. match a wrench to the size of the bolt and turn it, if it moves take the belt off (noting how it goes) and put the new one on saving you 280 dollars.

My Toyota Corolla has about 130 K showing,all original belts, the serpentine looks fine with no sign of checking on the under side. The timing belt,?? How many miles will they last, and does this engine...

Your 2003 corolla has a timming chain with no maintenance interval.
It is a good idea to replace your serpentene belt if it has not been replaced. Your motor is an interferance motor.

Serpentine belt

Hi there weekie,

Simple and easy. Really.
  • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
  • The tensioner pulley is on a spring loaded arm. Get your socket on the center nut of this pulley.
  • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt off.
  • Slowly release the tension.
  • You're done
