take off your serp-belt and spin your water pump, alternator, idler pully and see what squeaks or feels rough. your water pump bearings may be bad. the only thing you can do is change it. dont forget to change your thermostat and antifreeze. FYI your antifreeze is made with lubricants in it for your water pump bearings.

Depends on your experience, confidence, what tools you have and how much risk you can tolerate if you get into the job and can't finish it or do it incorrectly. A water pump poorly done could result in a damaged engine. It's a fair ways complicated for a novice but within the range of someone who's done brakes or replaced belts, hoses alternators etc. To see what you have to do, find a repair book for your car at the library. Otherwise it will cost somewhere around $200 to $400 depending how complicated the repair.

I have a similar problem with my 97 monte carlo, 3.1 liter engine. I am losing a full reservoir worth of water in 3-4 days. Two different mechanic told me it is probably the water pump is going/gone bad, causing it leak out of the peep hole. Replacing the water pump, should fix the problem.

Have you tried to checking the tensioner and the idler pulley? The idler is a fixed pulley on the driver side of the alternator. Most of the time this gets rusted during sudden change in the weather or its just the bearing inside it just worned off.
