The belt will not generally squeal, but the water pump often makes a "Scrapy-scrapy-scrapy" sound.

It will squeal if the bearing goes out-the most typical failure or lock up, throwing the belt or leak-from the front area of the pump.

That is simple... the one for the water pump... the belt goes around the crankshaft, over the water pump and around the alternator.

i had a similar problem on a 1990 Chevy 305 with a SERPENTINE BELT. I had replaced my power steering pump, when all was said and done it threw the belt off twice. the pwr steering pulley was mounted correctly THE SHAFT WAS WALKING OUT from the pump enough to cause a loud squeal then there goes the belt. I had a defective pump. i know C.I. is way smaller then mine but i hope this helps

It could grind, squeal, squeak, or make no noise at all.

It can be several things, either by themselves, or in combination. 1) the belt has dried up and isn't as grippy any more. This causes it to slip and squeal. There are sprays available to restore grip on belts which might help. 2) the belt has stretched a little, which causes it to slip and squeal. Retension, usually by adjusting the alternator position and it should be OK. 3) one of the auxilliaries(alternator, power steering pump, water pump) is about to seize. If it's harder to rotate the belt will slip and squeal.

the timing belt can cause a water pump to go bad if the belt is on too tight, because that will put stress on the bearings making it wear out rather quickly.

The pump bearings may be going bad or the belt could be slipping. Check to see if the belt is too tight or too loose.

I had the same problem, so I took the belt off and washed it in soapy water. I then took a wet, soapy cloth and wiped off all of the pulleys. The squeal in my Aerostar was caused by a leaking power steering pump, which leaked fluid on the belt, causing it to slip and squeal.

There is afew things that can make it squeal like the belt is worn and old or power steering fluid low or pump going out.

Loose belt -- replace or lubricate ADD-ON If it is a metallic squeal that continues for a minute or so after the car starts it could be your water pump bearing. Get your mechanic to check it out and replace before you need a tow truck.

the water pump is run by the timing belt the water pump is where the timing belt at in the motor

Yep, it could be the water pump or maybe the alternator. If a bearing is starting to go bad on that alternartor, it will make noise. Usually if a water pump is going bad you'll notice moisture coming out of the weep hole; but only if the seal goes bad; the bearing can chirp or squeal; take the belt off the pump; does the noise stop? turn the pump by hand does it feel loose and gritty as you turn it? if it's ok it should feel stout with no gritty feeling.

This is a non-interference engine. If the belt breaks you will be stranded but no damage will occur. Replace the belt every 60,000 miles. The cam belt drives the water pump, so I suggest you also replace the water pump at the same time you replace the belt, to avoid future labor costs when the pump goes bad, which it will.

On most engines, the water pump drive belt is also the timing belt.

According to an old Mitchel manual. There are 2 signs that the water pump has gone out. First, check the "weep" hole for seepage. The "weep" hole is located under the water pump so you'll have to get under the car to check it. The second is to listen for for a high pitch squeal. This can be confused with a belt squeal so be careful. Another thing to think about, is that a water pump is designed to turn in the direction of the belt; that is,it turns WITH the belt. There should be some clockwise/counter clockwise movement; there SHOULD NOT be any movement in ANY other direction. In other words,turning when the engine is running is good,but any movement when the engine IS NOT running,is NOT good. Also when the pump goes bad,you won't find a few drips under the car engine-you will usually find a small lake...usually but not always.

The water pump is powered by either a drive belt or serpentine belt. Follow the belt and you will locate the pump.

If the timing belt drives the water pump you should replace the belt at the same time as the pump.

Yes, the water pump on a 3.5L is timing belt driven.Yes, the water pump on a 3.5L is timing belt driven.

the water pump is part of the timing belt or chain. you have to take the belt or chain off to change the water pump. if you change the water pump, change the belt too.

The water pump is driven by timing belt, so, replace the timing belt while you are replacing water pump, because you have to take off timing belt to get to water pump.

The water pump is under the timing belt cover. The front most pulley the timing belt runs on is the water pump pulley. The water pump is located under the timing belt cover. The front most pulley the timing belt runs on is the water pump.

the water pump is turned by the timing belt and it is recommended that you change the belt at the same time as the water pump
