2001 Alero 3.4L Determining source of coolant leak Sign In

I have a suspicion my water pump is bad, I cannot pinpoint my leak, I checked the hoses around radiator and they all seemed ok.

As I am driving I get intermittent squealing from the serpentine belt, and my coolant levels are dropping quite often the last few days. I have the v6, what is the best way for me to confirm or deny that the water pump is the culprit? I have tinkered here and there with minor repairs, but my Alero now has 291,000 miles on it and I do not want to drop too much more cash into as a new vehicle is certainly in my near future...

I have heard getting the pump you screw on the radiator cap and getting to around 15 PSI should help show source of leak, but I do not know exactly where to look on water pump, or if there are any other common places a look would occur

Thanks! and sorry Mr Burrell for posting incorrectly before Angelic

You have the right idea. You just put the system under pressure with a pressure tester and just follow the leak to it's source.
