Fan belts squeak for several reasons 1 incorrect belt for pulley.2 belt running on the botton of the pulley and worn pulleys. To check measure across the top part of the pulley and the widest part (back) of the belt should be the same if not marginally bigger. V belts work best at t5he top of the pulley.If you can see that the pulley is polished at the bottom the belt is slipping and not driving Check if the pulley sides where the belt runs is not stepped from wear. Recheck the tension as new belts stretch slightly. If you have a multi groove pulley check the tension setting. As a last resort CRC make a product that is used to stop belt but it is best to fix the real fault first

SOURCE: belt (not ac) is squeaky

The squeeking is most likely coming from your belt's idler pully. They cost around 10 bucks and are attached with one bolt. Kinda hard to get to, so be patient.

SOURCE: My 97 miata has been having terrible squeaking

The alternator is loading up too much for some reason.
Had the same issue on my friend's 2001 Mazda Protege. Turned out the voltage regulator in the alternator was faulty. Had the alternator rebuilt. A week later, it acted up again! There is apparently another issue, but I have not been able to figure it out.
Unfortunately, I don't have a clear answer for you, but, one's thing's for sure. Mazda has to stop using crappy Ford electrics in their cars.

SOURCE: Squeak in low gear.

Try spraying the belt with a "dressing" spray. With the engine not running of course. If it stops, then your belts may need adjustment or replacement.

SOURCE: squeaking belts

If it's not the belts, it might be your alternator. I had the same problem. I would have the belts tightened, then the problem would come back a few months later. Ended up that the alternator was bad. Replaced alternator, battery and belts and it hasn't happened since.

It would have so goos if you were to confirm this in the first instant by observing the sound with a first hand inspection. Since you noticed it was the driver side underside, The car should have been jacked up on one side and rolled over to check for th noise. If the sound was evident, whether drive bearing assembly, hub, brake pads, calipers or bad suspension then the fault could be centred.
But is not evident then you could have jacked up the total front both sides and started you car to simulate the drive.
Now it could be confimed iff the noise came from the drive or within.
This must confirm before you change any part which is costly.

Squeaking? Maybe a mouse? lol.
This could be many things, from a fan belt squeak to a suspension bushing squeak to a loose bolt squeak. You need to try and pin point it a little better. Have a passenger put his ear to work by trying to locate it if it is coming from inside the drivers compartment.

Very loud squeaking


My guess is a pully is going bad on the tensioner. The new belt had more grip so it was able to force the bad pully to turn but now that the new belt is a bit worn it's beginning to slide as the pully gets worse...Does tha make sense? Solution: Remove the belt and turn each pully by hand. The pully's should turn very easily without ANY struggle. If you find a pully that has any stiffness ...(Or is hard to turn).....thats the bad one. Replace the bad pully and you will be a happy camper

When I turn the heater on the heater belt or fan squeaks and sounds like it is binding up, what can I do and where do I locate the heater belt or fan?


All heater fan motors are electric with no belt. They squeak when the motors are wearing out. If you look on your firewall, you will see the round fan with possibly a rubber hose sticking out the bottom. There are many pics online that will show you what it looks like. It is very easy to remove and reinstall

Heavy squeak when turning(like turning heavy rubber belt)Tribute


Your fan belt is slipping. As you turn the wheel you make a power demand on the power steering compressor. This compressor takes its power from the fan belt so as you steer the compressor shaft is harder to rotate and the belt slips as a result. The fan belt should be adjustable by loosening the alternator bolts and moving the alternator away form the engine and than re-tightening the bolts. Check that the fan belt is not worn, if there are obvious signs of wear or cracking then renewal would be the best step. Always make a sketch of the path of the belt around the respective engine pulleys before removing it.

it is likely one of the pullies failing. the most likely one is the tensioner pulley. only way to fix that is to replace it. also examine the front of your water pump. if there is any fluid "weeping" from the casting hole(s) at the front that would likely be your culprit
