Question about 1993 Mazda 626

1 Answer

Squealing I have a 1993 Mazda 626 2.0 liter. Cannot get the AC belt to stop squealing/ ticking noise. The A/C compressor has been replaced, and the A/C belt is as tight as you can get it. The belt squeals when you put fan on.

    We've got the same problem with our 2001 Mazda 626. We also replaced the compressor, which didn't help.

    When the heater or defroster is on the air conditioning pump squeals and I get a burning smell in the car.

How do i replace the AC? and what do i have to have to replace it?


If your car has an adjustment for the belt, I would suggest you tension the belt a little more first. A slack or loose belt would also cause that problem

I have a loud squealing noise upon starting the car. the squealing normally lasts about 30-45 seconds. sometimes the noise will appear aftrer pulling off from a stopped position, as well. all belts


Try to tighten the belts a little firm.Sounds like when engine idling no squelling only when about to take off .Some times belts may seem ok on the outside but if you look on inner side you tend to see cracks in the belts .

AC Squeal


Odd,possibly the AC is overcharged,or a pulley(either tensioner or
PS ) is out of line. Wish I knew what kind of vehicle. Might help.

Can't find the source of the squeal


Year make and model ??
The belt could be glazed and slipping even if it is tight.
You could have a weak belt tensioner too.
The noise when the ac or heat is turned on can be the extra load from the ac compressor or the alternator. The compressor cycles on and off especially in defrost mode.
The load from the alternator is the first noise of the day. As the belt warms up it becomes better at handling the load of the accessories.
Even tho the belt looks fine, you may have to replace it to get rid of the noise.

What would cause my ac belt to break on my 97 dodge caravan the pullies move without the belt being attached ,but we did have a big squealing noise when we used the ac..


The squealing is from the crankshaft p[ulley turn the belt on another pulley that is not turning as faster, Let it sqeal long enough and it will burn the belt in half. The pulley on the A/C maybe turning freely, but when you engage the A/C, the compressor itself is not, causing it to squeal. My guess is that the compressor is locking up or you have added to much freon. Having to much freon causes to much pressure buid up and will stop the compressor.

At start up I have a loud squeal on my 99 Mazda 626. Both belts are new and so is the alternator. The squeal only last for about 10 secs or so and goes away. I have started it in neutral and the squeal is...


Does your car have air conditioning.? Most cars use the A/C compressor to dry the air for the defrost. It will also come on for a short time when you first start the car. With the engine running after the squeel has stopped , try turning the A/C on , If the squeel starts again , then I would think your A/C compressor is seized. Also . are you sure the 2 new belts are tight enough?

Car squeals when AC is turned on for first 10-15 minutes.


The Belt of the a/c to the solenoid pulley is creating the noise.
So while the care makes the noise pour some water into the belt and the noise will subside. the it is confirmed.
Stop the engine and check for play in the belt if so tighten the belt If not use some chalk power or candle wax to be rrubbed into the belt that was making the noise - the a/c drive belt - .
Now start and check . the nosie would be reduced or gone.
Replace the belt sooner or later.
