Had the alternator and belts replaced on my 2000 Mazda
Protege ES.

I took it back once cause belts started squealing bad
under the slightest load....so they tightened up.

Now they are squealing just as bad!

Does it take several adjustments on new belts? Or is
something wrong here?

Sounds like whoever is doing the work does not own/use a belt tension
gauge.

Be sure you have the proper size belt (width) if too narrow this is the
problem. Been there done that. WW

Or there's some other cause, and they're just tightening the belts and
crossing their fingers.

Dirty pulleys will also cause squealing.

My guess is that you have some oil on the belt or that your belts aren't
quite the right size. It may be that the belts are selected by the shop
for a close but maybe not an exact fit to reduce the amount of belts
needed as inventory.

If you have oil on the belt, find the source of the leak and fix it.
Otherwise, verify that there's nothing wrong with the belt and tighten
it. If it has been adjusted to the tensioner's limit of travel, you'll
have to replace the belt.

I like to adjust my belts as loosely as I can because I think it's
easier on the bearings. This is not practical for a repair shop that
should adjust to specs.

No. But what you do need to be aware of is that the alternator/water
pump belt on the 1.8l engine needs to be run rather tight. If you
don't get it tight enough, the alternator will squeal like crazy. More
than likely, that is the belt that is causing your trouble. If you
have the 1.8l BP engine, that is where I would start troubleshooting.
With a cold engine, start it and run it for a few seconds until the
belt starts making noise. Then shut it down. Pop the hood and stick
your hand down by the alternator. If the alternator pulley is hot, you
just found your problem.

Depending on how long you drove it after it started making noise the
first time, you might have glazed the new belt over, in which case the
only fix is to replace the belt again and properly tension it. The
shop you had service the car should warranty the work if they are
reputable.

Thanks

yes it is squealing like CRAZY again now

I'm going back to mechanic and question his use of
proper belt..... or the quality of belt

I've had it tightened once already which I know is
normal..... but have never had a problem of multiple
tightening's weird

If you can lay a straight edge against the two pullys, you can check to
see if they are in alignment.If something isn't dripping onto one or
more pulleys or the v belt, might be something wrong with the v
belt.Could be the v belt is the wrong size/length.V belts grip along the
sides, not on the bottom.Get enough miles/wear and tear on them and they
will stretch.

Tomorrow, I am driving my big old 1983 Dodge van to a shop for two new
mufflers and new tail pipe.Those exhaust fumes are killing me!

When my v belts get loose, I get a few of my old pawn shop tools and I
tighten up those v belts myself.
Old rule of thumb ''Trick'' is, if you mash down kind of hard on the v
belt with your thumb, and if the v belt pushes down more than half an
inch, (or is it an inch? I forget) the v belt should be tightend up a
little bit.Some auto parts stores sell v belt dressing stuff for
squealing v belts.

57 degrees out there in my flower box on my front porch right now.74
degrees inside of my house.
