Default Quick Water Pump Question

Do water pumps make any noises before they fail and begin to leak coolant? When I changed my oil last, I noticed the coolant resevior was down very slightly. The past few days I swear I've smelled coolant when I first enter my car.

I've also noticed at idle a soft "squeaking" sound that tends to disappear after the engine is up to normal operating temperature. Could this squeaking possibly be my water pump? The car has 101K miles with the original pump, so it is probably due to go sometime soon.

Thanks in advance

I doubt that the squeaking is related but you never know. The best thing for you to do is have your cooling system pressure tested, that will tell you where the coolant is going. There are a number of other possibilites besides the pump, including but not limited to: leaking hose, leaking heater core, leaking raditor, headgasket, etc. etc. Another thing to keep in mind is that it can be good practice to replace timing belt driven water pumps along with the timing belt (as you MAY be about to discover the hard way.) You should have replaced your t-belt at 60K, and will need to again at 120K. You have to remove the belt to replace the pump if you do it now at 101K. Since the pump only costs c.$60-80 (I'm guessing..) and labor for the t-belt R&R alone will be more than that, not replacing timing belt driven water pumps at the timing belt replacement is false economy IMO.

My fiance just had her timing belt and water pump done on her Legacy Outback. The dealership did not charge any labor for the water pump, only parts, as all the work with removing the timing belt was already done. If I remember right, the guess of cost of $60 - $80 is about right. Saved a chunk of money.
