Screeches sometimes when i start it - 1991 Toyota Camry

I would just change the drive belts. They're inexpensive and definitely worth it.

Check ur fan belts/ serpent belt .open hood you stand in front of car have someone start it and see if make noises

could be your serpentine belt. usually when they get worn they will start to either slip or cause a very high pitched screeching noise. to verify that is the cause get some water or brake clean in a spray bottle and spray it on to the belt while the vehicle is running. if the noise goes away for a moment you found your cause. if not then its something else. Hope this helps

If you hear a click under the hood from the starter the starter solenoid but starter is defective and you should rebuild it. If that is not the case I would replace the ignition starter switch, this is the electrical switch the key cylinder actuates to turn on the electrical system and engage the starter.

Are you saying the serpentine belt is screeching after the engine starts, or the starter is screeching when you are cranking the engine ?

Remove the belt and check all pulleys for smooth operation. any binding at all is amplified when belt tension is applied. also check the belt itself...If it's glazed or dried out, it can be noisy.

I would guess that you have a stretched or loose serpentine belt. Common problem.

hi as the timing belt is toothed it would not slip however it may be loose and in need of renew? as you do not mention milage ie period the belt is due for replacement ? the screech if this above is problem? would/could be the belt slip on the adjuster bearing which should also be renewed with belt i would first check out the alternator/p/steer belt as the loading of belt if slack/worne when starting from cold will give screech as it starts to overcome load of alter and especially p/steer oil pump then noise ceases as engine warms?? if you drop this belt off bfore you first start from cold ? would give an indication of which belt req's attention ? ps! as for age of car/milage? would not ignore the recommended milage for timing belt renewal ? hope this helps you diagnose problem ?
