Question:

My car squeaks every time I turn it on. But the belt is tight and I have a new water pump and alternator.?

Was I supposed to lube the water pump or what. I really don't know what it could be making the noise now. But it goes away after about 5-25 seconds of running, what could it be?

Answer:

If your car is a Chrysler product it is most likely the bearings failing in the idler pulley on the belt tensioning arm. I have replaced this after failure on 2 dodge mini vans. Don't wait too long, if it fails completely the belt will be ruined and leave you stranded.
It rather sounds like a starter situation except for the actuality it stalled, and the front belts are shifting. If the front belts are shifting then which potential the starter is effective and the crankshaft is popping. pondering there's no compression or some thing i might want to assert the automobile has significant engine damage. What it would want to be although I unquestionably do not recognize. each of the pistons popped off the rods? each of the rods snapped jointly? lol sorry i did not help, I unquestionably do not recognize rather.
no, there's no lubing the water pump. You can have a dry bearing or worn bearing in your Alternator, power steering pump, A/C pump, etc. All these can contribute to a squeak or squeal that can drive you crazy. Glazed belts are another thing, did you check the other belts when you changed your water pump belt? is it a serpentine belt that does it all, or do you have 2 or 3 separate belts? Usually if the noise goes away after awhile, it's a bearing problem.
It is the belt slipping on the pully before the material warms up from friction to make it grip better. The squeeling sound is the pully and the belt slipping as the motor is warming up. It is nothing to be concerned about and it is definately NOT your water pump. If the sound bothers you, as it would me, then goto your local auto parts store and buy a cheap can of belt stop slip. It costs less then five bucks and it is a sticky substance like stickum or sapp in a spray can that will help your belt to better grip the pullies and it will stop your problem. What you want to do is this, wait until your car is cold and have someone start the car while you are standing over the motor ready to spray the can onto the belt. You will instantly hear the noise quit as soon as you squirt the can onto the moving belt. Once the engine starts and the belt is moving, just hold the spray down for 3 seconds and it will coat the underside of the belt and your problems will be over. You might want to try to spray an area that will allow the spray to coat the underside of the belt, i.e. the part that comes in contact with the pully. You only want to spray the belt while the engine is running and the belt is moving. That way your 3 second squirt will coat the entire underside of the belt as it moves under the spray can. Kinda like oiling a bicycle chain while moving the pedals and spinning the chain while holding the can in one place as opposed to oiling the chain while the chain is stationary and trying to cover the whole chain. It is impossible to reach all the places becuase some will be hidden behind other parts. That is why you want your motor running while you squirt the belt with the can of sticky belt stop squeel. It will stop squeeling immediately as soon as you spray it on the moving belt. The guy at Pep Boys or Advanced auto parts should know what you want.
Check closely, you may find that the pulleys are not lined up completely. Have you had the power steering pump replace? Very common to have the pulley not pressed on completely, causing the ribbed belt to not ride properly on the pulley, causing squeaks.
