Most likely a belt but everything is tight and the belts still have good groove and I see no smooth spots indicating slippage.
Any ideas?
Thanks

I know they are going to bash me for saying this... BUT with the engine running rub a candle on the belt. It made my belt stop squealing. And for Gods sake, be careful.

Wouldn't putting wax on the belt make it prone to slipping? Yeah, it probably won't squeak when it slips, but I would bet it would slip worse than with no wax on it.
Just put a new belt on.

Belts don't always "look" bad. I would bet it is the belt slipping. Either replace the belt, or try tightening it a little tighter.

wax works.

wax works.
I did a google search on wax and a squeaking belt. Sounds like it works and doesn't make the belt more prone to slipping. Interesting.
-
You've been told twice already - I'm going to make it thrice - replace the belt.
The belt is squealing because it is slipping under the load of the alternator as it tries to restore the energy just taken from the battery to start the engine.
-
A belt can "feel" tight when it in fact isn't. You can measure it by
deflection is best IMO. Google it. If it measures out in spec then
replace the belt for sure.

replacing belt
thanks

Any guesses would be appreciated
Replaced belts but the noise still remains. Today I started the Zuk and it made the whistling\squeal for 4 minutes while warming up. When I drove away it made the noise and then it stopped when I was at a light or stop sign but when I accelerated it would squeal and when I was at an idle it stopped. After another 5 minutes it stopped all together.
A/C Compressor maybe?

http://www.industrialrubbergoods.com/synthetic-rubber.html (http://www.industrialrubbergoods.com/synthetic-rubber.html) With china and India sucking up all of our natural resources get used to it, look for a belt in the back with a lot of dust on it from yester year while at your local auto parts store, maybe a smaller one that does not have so many sales as the larger chains.
-
I'm not familiar with that motor but does it have an idler pulley for the a/c? Does the sound change or go away when you turn the a/c on?
-
Make it tighter than you think it needs to be. Suzukis are very finicky about belts. They dont seem to like Gates and Dayco. Import belts like Bando may be better. Every time i replace a belt on a Suzuki I have the same problem and have to put it on really tight.
-
The belt IS slipping - the reason why is in my previous post.
If you have replaced the belt and it still squeals directly after startup, tighten it.

The only time the AC compressor has drag on it is when the AC is on. So if it is squealing and the AC is off, then it isn't the AC compressor.
Did you replace both belts, or just the AC/PS one? In my experience, the AC/PS belt will not squeal unless the AC is on, or the belt is obviously too loose. The alternator/water pump belt is the one that will be the one that will squeal, if you have a sqealing belt.
Did you clean the pulleys before you put the new belt on? If there was some oil or something on the pulleys, then that can cause a belt to slip and squeal. If you didn't clean the pulleys (I use brake cleaner and compressed air), then the oil would have gotten onto the new belt.
But my guess is that you either replaced the wrong belt, or if you replaced both of them, you didn't get the belts tight enough.

HOW ABOUT THE TIMING BELT TENIONER MAKING THE NOISE
-
Most waxs provide huge amounts of traction, you wouldnt load up the top of a surf board with something slick, you apply wax for the added grip it provides.
One thing about the zuki's is that the alt belt travels right under the coolant outlet and just a few drops of coolant contamination on the belt will make it squeal like a pig. make sure any buildup on the pulleys is cleaned off when changing the belt.
Some belts will also contain different combinations of rubber etc and will be overly hard and slick untill warmed up
I have bead blasted pulleys(dont use sand) to remove surface contaminations.
-
I'll try changing and tightening the belts
I'll let you know what happens

Not to throw a wrench in any ones theory.
Start the rig (cold ) so it starts squealing.. Open the hood so you can determinen what is making the noise..IE: bad belt , bad bearing in water pump, bad bearing in alternator, bad pulley alignment....etc.
Over tightening a belt can and will add to much load to the alternator front bearing. This causes premature bearing failier in lots of alternators...We see it in the shop all the time....
Also never ever paint the belt track in pulley.
The noise in question is caused by a load somewhere in pulley belt system...Locate that and you will have solved your problem..
-
My 88 does the same thing occasionally on start ups. From what I can tell, I think it's a tad bit of oil that gets on the belt once in a while causing slippage. Mine only occasionally does this, hence my oil theory, cuz my engine does like to leak!
-
1st time starting it with the new belts and no squel - Hopefully it stays that way
-
You may have a pulley out of alignment. New belts will make the niose go away (for a while). If it comes back sooner than normal belt wear can explian I'd say that's the original problem.
