Question about 2001 Buick Century
Hey guys, There is a loud squeaking that sounded like it was coming from the water pump, so I replaced the water pump and checked all the other pulleys which all felt ok. When I started it up it was gone for about 30 seconds but came right back. Its pretty loud and gets louder with acceleration. Does anyone know what I should try next? Thanks for the help...

Sounds like u could have another leak possibly, coolant or oil getting on the belt, also look for the belt tensioner, when they go bad they will squeak really loud

I would Look For A Vacuum Leak, Given the Fact that ALL that Work was Done in a SHORT Amount of Time, And The Brakes ARE VACUUM ASSISTED, that when Brakes are applied the ENG. Light Comes on, Seems to Me It all May be related. It does not take Much to Pop A Vacuum line OFF Accidentally

SOURCE: installing the serpentine belt
The power steering pump is only held on by two bolts that are removed thru the pulley holes. Anyway you don't have to remove the whole motor mount just remove the nut that holds the mount just to the left of the balancer. then remove the stud with a inverted torx bit. then remove the sleeve the stud went thru and then the belt will come off.

SOURCE: I replaced the water pump and cut the old serpentine belt out that was tangled around the pulleys Now I cannot figure out how to get the motor mount off to get it up around the alternator pulley
Here's a link to a web site to give you a diagram for your serpentine. Just insert the year,make,model, and engine size. Once there, you will see to the left a link below the part number called "Routing diagram". Best of luck on your repair.

You may not need a serp tool. Look for a place on the tensioner to fit your ratchet into then turn to push tension off. If there is enogh room to get the ratchet in

Check if screeching is related to engine vacuum.
Briefly remove (or loosen off) the oil filler cap - if noise immediately stops high crankcase vacuum is the cause. Check / replace PCV valve to fix.
If above is not the cause, listen with a short length of hosepipe to try and narrow down noise source.
Silicon lube spray or pencil lead graphite on a selected belt should cause sound change if it's caused by that belt.
