Question about 1993 Saturn SW2

1 Answer

Air compressor noise

The air compressor pulley squeels when the A/C is turned on. Do I have to replace the whole compressor or can that pulley be replaced. If the pully only can be replaced, does the refrigerant have to be discharged.

A general rule of thumb is that if you have a bad a/c clutch you should replace the whole a/c compressor. it has been my experience that usually when you replace the clutch only a short time later the compressor fails because the seals get worn from the malfuntioning clutch and you lose the refrigerant and you have a locked up compressor. if you have a 134a system the whole pump should only cost about 130-165 dollars for a sanden style pump. the clutch alone cost half of that and maybe more. hope this helps. by the way when you open the system make sure that you replace the dryer moister will get in when you open the system and it will plug the dryer. when fully charged the system should read 35 psi on the low side and 130-150 on high side. also power wash the condenssor which is mounted on the front of the radiator this will allow the outside air to flow more freely through the coils and fins and make your a/c run more efficiently. please rate this solution......thanks

Squeeling after replacing all belts and the tensioner pulley?


Still sounds like the belts, not much will cause that type of noise. You can completely remove all belts and start engine to see if noise is still there, no harm to engine to run it for a minute or two with no belts. You will know for sure then.

We just replace the radiator, fan, belts, water pump and pulley in my ford f250. It runs fine w/o a/c. When I turn the a/c on it makes alot of noise and smoke comes out of the compressor unit under the...


The smoke is probably coming from the Serpentine belt. Flip the belt and see if it is now starting to be SHINY. The belt is going faster than the Compressor has the ability to turn. More than likely, the Compressor is partially seized and needs to be replaced.

Grinding noise coming from one of the pullies (bottom one).its a 93 cadillac 4.9 engine.


Good morning, If the noise is coming from the pulley closest to the radiator the it is the air conditioning compressor. You have a couple of repair options: If the noise comes all the time, a/c off then you have a failed pulley bearing to repair you can just replace the bearing or replace the pulley and bearing as a unit and the clutch, you can replace the whole compressor. you can get a smaller belt and by-pass the a/c compressor. getting a belt will be a hit and miss attempt because I can't tell you the length belt you need. You might try putting a small rope around the pulleys the same way the regular belt is routed then take it to a parts store to have them attempt to match it up (take old belt with you so they can see the width. This needs to be fixed because the noisy pulley will lock up, break the belt, when that occurs you won't have any power steering, the water pump will quit and the engine will over temp (run hot). Hope this helps

Air conditioner


The squeeling is the belt because the air compresor is likely seizing. At idle it can't turn the compressor, in motionthe compressor probably turns and cools the air. Most air conditioners come on when the defroster is on.

The heater works but when the defrosters are


The Air conditioner compressor is seizing when the compressor clutch trys to engage. When you put on the defroster the air conditioner automatically comes on to take humidity out of air.

I have a 2001 Sonata. I have a squeeling pulley.


It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps

A/C quit blowing cold air after a loud squeeling noise stopped!


Look way down on the engine front area passenger side for the compressor.
Is the belt gone?
Check the belt tensioner pulley....can you turn it?....is it seized?
If it is OK then try and turn the compressor.......and the idler part of the compressor.
If the compressor is seized.....why?
Usually lack of oil in the system,or an overcharged system.

Once you have removed the 134a gas from the A/C system before removing the compressor and before installing the new compressor make sure you add the correct amount and type of oil into the system to prevent another seized compressor after you have flushed the system to remove contaminates such as old compressor grindings......if the compressor was seized.
You will also need a new receiver/dryer once you open the system to the moisture in the air.
Do not expose the new receiver/dryer to air....install last.
Vacuum the system well before refilling with the correct amount of 134a.
At 70 to 80 degrees outside temp........a vent temp at medium fan speed of 48 to 45 degrees should be a full charge .......use this reading if you do not have a electronic scale and/or A/C machine.
DO NOT OVERFILL THE SYSTEM.

Squeeling belt, have replaced idler pulley, squeels when idling and turning with a/c on. Could it be the power steering pump?


Try using a very small spray of silicone spray on the belt next time you're hearing the squeal. If it temporarily stops, replace the belt. Check the p/s fluid level, if it's low it could cause the pump to make noise. Also if it's low, you have a leak, check all lines, connections and pull back the bellows boots on the p/s rack (if rack and pinion). Finally, pick yourself up a mechanic's stethescope, good tool for diagnosing accesory noises. Listen to all components while duplicating the noise.

Engine noise on area of pulleys and sometimes engine tries to sto


Don't know if this helps. Had squeel in belt area. Occasionally engine would stop when squeel got loud and sometimes engine would try to quit while going at various speeds. Found tensioner pulley was bad and changed it. Still squeeled and engine would stop when squeel got loud. This time while sitting in yard. Further checking found binding in power steering pump. Will be putting on new one tomorrow. Hope it works. Will update.
