There is a loud squeecking noise coming from the water pump and the serpentime belt isnt loose!I dont know how long it would take a mechanic to do the job?
Spray some water on the belt while it's schreeching to rule the belt out. They often make noise, even when tight.
type into search box how to replace water pump how to replace water pump s-10 how to replace water pump chevy about two to four hours maybe depending on mechanic and how busy the shop is and before you go and start replacing water pump if its not leaking its not bad yet and most likely will be a bad pulley or belt tension-er which go bad before water pump most of time you can spray water or wd40 on pulley to check if motor not running hot and you dont see any coolant coming from water pump most likey not bad belt tension-er pulley cost about 30 bucks anyone can replace in about 30 minutes
