When we replaced the fan clutch, the water pump pulley shattered, being one of the lame plastic ones. I replaced it and the water pump, and the thermostat, and coolant and the belts. Tensioners may need to be done too, but haven't ordered them yet.

170000 mi Done diagnostic tests, on many systems, over last several months. It began with bad idle, progressed to stalling. Now it won't run, nor even start. At this point I'm fairly sure it needs new fuel pump. Need to save up $180 to buy one.
