Question about 1994 Mazda MX-3

Open Question

Mysterious oil leak from engine onto alternator/power steering belts - where could this be coming from?

It's causing a squealing sound on both belts and ended up chewing right through the alternator belt. The alternator is FINE. Potential buyer of the car said it was 3 piston rings that are non existent....

SOURCE: Replacing 2 belts on a 2000 Mazda Protege

I recommend that you go to any Auto Parts store and by a repair user manual for your 2000 Mazda Protege.  They have pictures and arrows and stuff that you will need to do the whole job.  The non-Mazda version will cost approximately $15.00.
Because of the tensioner that may come off when while you are doing these belt changes, it is too complicated to talk you through this.
But with the manual, I am confident you can change them.

SOURCE: alternator drive belt squealing

yeh, mine did the same thing with a hydralic belt. it was the bearings. mazda capellas use a lot of 6202 bearings which, luckily, are fairly cheap, and are commonly used in pool pumps. so you can find them at pool pump repair stores. although pool pumps use 6202 2RSR bearings. these are just the water proof type, but are excactly the same size and can be used.
to test if it is a bearing problem, remove the belt and try to twist the individual wheels by hand, you should be able to turn the 2 smaller ones.
from memory the alternator belt is in a fairly in accessable postition so the belt is going to be hard to put back on.try other things first, like wiping the inner side of the belt with a dry cloth to remove moisture.
worst case senario is your alternator has, or is starting to, seize up and you need to replace it.

SOURCE: Belts squealing

is your belt slipping? You may have a bad tensioner pulley. Check all pulleys make sure they will spin and not lock up, if they feel really tight or after rotating them around several times they get tight replace

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.

WHAT IS THE LIKELY CAUSED OF A LOUD SQUEALING NOISE COMING FROM THE ALTERNATOR SERPENTINE DRIVE BELT SYSTEM ? IS IT THE ALTERNATOR OR SERPENTINE BELT?


serpentine belt is getting old and hard and the cold weather was causing it to slip
check belt condition ( small cracks across the grooves = scrap and get a new one) and check tension

2003 Kia Rio new fan belts squeal when lights,heat, or radio are turned on, especially when car is cold. caused a fuse to blow last winter


Hey Anon, Are you SURE you got the correct belt?? Something does not sound right about this...???... Double check all the pulleys when the belts are off...the alternator should spin freely, all the the idler pulleys should spin free..(ones that just spin and guide but are NOT connected to anything)!! This very thing happened to me...it was a $12 idler pulley that did nothing but spun and guided the belt..

Trying to figure out why i am having squealing issue all new altternator power steering pump pulleys and belts


Belts normally squeal when they slip and they slip because they're not tight enough or in the case of a V belt because they're too narrow. Make sure they're tight enough and they're the right belt.

At startup, amp gage low, lights flicker. belt squealing. then after warm up, gage normal no squeal. alternator bad? Use to do when blower motor on now all start ups.


Thats what it sounds like. That would cause all your problems. You could start the jeep and then take your hot side battery terminal off. If it dies asap, your alternator is bad. Hope this helps. Best of luck.

Daughter's 1999 Jetta; smelled burnt rubber when leaving work last week. Car ran fine. Yesterday, started squealing (sounded like belt slipping) when started. Later in day, she turned car off and sat with...


It sounds like the alternator belt or the alternator is going bad. The squealing sound was probably the alternator belt. the alternator belt might need to get tightened or replaced or you may need a new alternator. The alternator keeps the battery charged. When the alternator goes bad the battery can not be recharged. You also should keep the power steering fluid up to par or the power steering will go bad on you.

2003 Lancer ES High pitch squeal and constant squeak


Shortly after replacing the serpentine belt in my lancer, the same thing happened. It is NOT the timing belt. Belts squeal when they slip. If your timing belt slipped it would cause your car to run funny.

have somebody check the belt for wear (or do it yourself), replace if necessary. If it doesn't need replacement, just tighten it.

If you have the 4cyl engine that I have, the tightening is kind of a pain in the ****. Not a great design by mitsubishi. There's a pulley near the front right corner of the engine in front of the alternator. the belt should be running around this pulley GROOVE SIDE OUT. This is the tension pulley.

To tighten:
1) Lightly loosen the bolt in the center of the pulley (slightly loosen, DO NOT REMOVE).
2) Under that pulley there's another bolt. You can see that the bolt goes through a piece of metal
attached to the back of the pulley. Figure out which way you need to turn the bolt to move the
pulley toward the front of the car. (i don't remember if it's right hand thread, or left hand) This
puts extra tension on the belt. You probably don't need much. Over tensioning the belt can
cause pulley bearing failure. If you haven't done this work before, ask someone for
help
. It's better to tighten a little bit, a few times rather than overtighten once.
3) Don't forget to ReTighten the bolt in the center of the pulley.

If there's lots of cracks and pieces missing on the ribs or grooves of the belt you should replace it first.

Happy repairing,
Cliff
