yesterday, just out of sheer coincidence, i decided to check the water level in my res. to my dismay, no water movement. then i realized that the pump was getting power due to the tell tale 60hz hum but no impeller movement. drained the system, took the pump apart and found that the plasic bearing pressed to the inner magnet had seperated and was binding the impeller to the shaft. i epoxied the parts back together as close to original as i could and re-installed. it's now working fine. the real question is, why the failure in the first place? i run a mix of distilled water and prestone with just a drop or two of water wetter. could it be that i had too much prestone and the viscosity of the coolant was too much for the pump? if you guys have any informed answers i'd appreciate it.

p.s. the pump has only runs when the compter is on and was installed in december.
