This is your alternator belt squealing. The belt needs to be tightened or replaced. When the defroster comes on, it puts more load on the alternator causing the belt to slip.

Alternator squealing


Could be just the belt... if not the belt then most likely the alternator bearings are bad.. you can test this by removing the alternator and turning it by hand and listening to the rear for squeeks or a grinding sound.. good luck

Bad sqeel or screech w/defrost mode, when compresser is engaged. turned it to just heat it stoped


There are a couple of things that could cause this.

First, a worn belt can result n slippage and squealing when the compressor load is applied.

Second, a worn out compressor clutch can result in a metal-to-metal contact when the clutch engages. This will cause slipping and squealing.

Third, the compressor shaft could be locked up, so that when the clutch engages, the belt slips over the pulley and squeals.

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?


Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

Toyota Tercel belts are squealing


I have been having the same problem with the alternator belt squealing, most noticeably, when using the heater fan , accelerating, turning the headlights on. I have a 1997 Toyota Tercel CE 1.5L 4cyl with no A/C. I just tightened the belt tight enough that there is no give to the belt and it does not squeal anymore.

I also used a Goodyear Gatorback from Napa belt which seems to be nice and quiet when tight enough.

I believe it's my alternator belt that is squealing. It does this when cold and when I tax the alt. ie: turn everything on. like rear defrost,headlights,heater fan. after the squealing stops you can hear a...


Check belt tensioner adjustment. Spray WD 40 on belts and pulleys and start. If no fix .it is most likely the rear bearings on the alt. before you buy a new one shoot some WD in the rear of the alt through the slits to the shaft. No fix take it to your local chain parts store and they will check it for free.

AnWhat causes a loud squealing sound when I start the engine and/ or turn on the defroster?


will try to assist you. the loud squealing is most likely a belt thats loose. when you start the engine it squeals for what?30seconds? when you turn the heater on it puts a drag of power from your engine and the engine is trying to compensate. so it [engine] asks for power,puts drain on engine and the loose belt squeals.a loose belt will squeal,simply because it's trying to do it's job.but loosing traction. so it squeals. check for play in belts with engine off of course. grab each belt by hand. if it has more than1/4 inch play or [slack] it needs adjustment,or replacement. hope this helps! thank you for choosing fixya.com we are here for you 24/7 7days per week! good luck!!
