1995 Metro - Belt Squeals like a pig.... (by 2 users)

By Hart - usenet poster


Have a 1995 Geo Metro 5 speed (3 cylinder engine) that the
belt (only has one) squeals like a pig. Recently replaced
the alternator which went bad. The new alternator then went bad
after 6 months and the shop replaced it (no charge).

The squealing is a chronic problem and I've lost several belts because of
it. Usually after a few miles the squealing stops. I have suspected
a water pump (replaced in 1999) but the shop says no, that there is a
TSB on it that says new brackets are required (?).

Can't find a TSB on this problem at alldata.com. Anyone ever come
across this. Thanks.

Pablito

i had this same problem and went through many belts! The problem is the groove in the pulleys on the water pump and crank. clean them out with a knife or a sharp point and be sure to do all the grooves in both pulleys

I had the squeking belt problem on my 95 met. Try using a 4 foot long pipe to get good tension on the alternator and belt before tightening the alternator in position. I fought the squeling belt for 6 months before I was told to try this. Since I got good tension on the belt by using the pipe, the belt has yet to make a noise for the last year and a half.

You say you only have one belt. Actually, you have a second belt for the cam. It can't slip and squeal, but the tensioner idler sure can squeal. Is it possible that it is beginning to wear out?
If it consistently squeals when it is started, get a 2 foot piece of fuel line and listen for where exactly where it is coming from. You may need to have someone else start the car while you're under the hood listening with one end of the hose to your ear and moving the other end around until you identify exactly where it's coming from.

I also have a 95 metro 3 cyl 5 spd and have not had this problem it has
100,000 miles on it.Check for pulley misalighnment,this will cause the
problems you are having.prematuer bearing,belt failure,etc.Any extreem load
on the belts such as a bad water pump shaft or siezed generator shaft will
do the same.hope you get it fixes and so long,Norm

This problem can be also that the belt might need to be changegd if not maybe
that the tension needs to be increased.

thanks. the shop had to replace the new alternator they
put in 6 weeks ago. They have checked the pulley alignment and
said it is OK. the belt has been replaced.

They are not sure why 2 alternators have failed, one lasted 6 months the
other six weeks. I have long suspected a problem with the water pump but
2 different shops say it's OK.

We'll see if it works this time. The belt still squeals when it starts up
but then goes away after <30 seconds. This is only D+2.

You are not alone man,my 97 3cyl is doing the same,specialy in cold weather,
squeals like a pig for a 15/20 second,the alignment of the pulley is ok,I
cleaned the pulley with brake cleaner so no more greasy residue,I adjusted
the tension again, (the new belt didn't squeal for about a year) and still
the belt slip on something,I assume the alt, but I have no problem spinning
it by hand, the problem is likely under load right after start.

This is just a thought, but if I were having this problem, I would clean the
pulleys(which you did) and then rough them up with sandpaper. Sometimes,
you just have to "rig it". GW

I't my feeling that there is a greater than normal load on your
alternator. The car burned two already. I think the belt is squaling
from a hard pulling alternator under a great load. Have your battery
load tested. (is it original to the car?) An alternator continuously
charging against a battery that will not charge up, can overheat and
fail over time.

Update on the Murderous Metro...

After a little more than 1 month of service, another new alternator
has given up the battle. The Metro from Hell has vanquished its 3rd
alternator in 3 months.

Will be taking it to a GM dealer after the discount auto shop replaces
the alternator. Hopefully the heavy hitters can properly diagnose the
problem.

Pulleys have been aligned and belts have been replaced but the mystery
continues. stay tuned.

It needs shims to properly align the pulleys.

Or, it just sucks to be you.
