As far as blocking flow goes, if the mesh is say 1/4 the diameter of the coolant passages, then it should block debris without significant effect on flow. I guess the mesh would have to be fairly strong, I could see all the plastic impeller parts being stirred up might rip the mesh, sending pieces of mesh into the motor.
