I have a 2000 chevy impala with 85K on it. I have heard/a weird rattle noise from under the hood for some time now. I once asked about it on here and got suggestions regarding front end problems. I had that checked out and the front end is good. I still have the rattle noise along with a high pitched, but not very loud, squeeling noise when I accelerate. I am leaking coolant and it seems to be coming from near one of the belts. Is this a bad water pump? If so how expensive of a fix is it and how involved of a repair is it?
It sounds like a water pump or maybe a loose connection. It is probably time for a water pump if it hasn't been replaced yet. Parts will run under $60 and it probably involves an hour of labor. The Impala is a big car, it shouldn't be hard to get to and remove. Taking it to a shop will run under $100-$150 for everything.
