Was squeeling at waterpump.replaced with new pump.squeal went away.after it idled abot 20 minutes,it started to chip,then squeal again.is it possible trhe new bering in water pump,was not lubed?,,and went bad?

I'd guess it's the water pump.

There are a number of possible causes. Try to isolate the source of the squealing. You can pinpoint sounds using a mechanics stethoscope or a piece of tubing. I would suspect a bad tensioner pulley or a bearing in the alternator, water pump, power steering pump or a/c compressor. You could remove the belts and start the engine to be sure the sound isn't coming from elsewhere. Adjust the tension of the belt if not equipped with an automatic tensioner. Belt dressing spray might help in some cases.

Replace the crank pulley before it costs you an arm and a leg. It has caused this problem. don-ohio

The pump runs off a belt as well, if there is a pump problem it might make the belt squeel

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?

The squeal is coming from the alternator belt, When the temp is low, the belt is hard and glazed and lost its ability to create friction.

the fuel pressure should be constant no matter what rpms. the noise is probably caused by the installation of an aftermarket pump.

You need to tighten your fan belt,loosen the top and bottom bolts on the alterntor and pry it side ways until it is tight.If it still squeels then do it again to make it tighter.

Replace the belt and tighten after the belt has squeeled you have killed the belt.

Belts stretch from new. Try to tighten them again. Hopefully the are not glazed or this may stay with you.
