Bad Wobble in Water Pump Pulley
I've got a really bad wobble in my water pump pulley that is getting worse and I figure I need to get this sorted out before I blow a headgasket in the McDonalds drive thru. I know its not being caused by the harmonic balancer (crankshaft vibration dampener) because I just replaced that.
My question: Is it possible that only the pulley is going bad, and I can just replace that instead of the entire water pump? If so I'd like to first remove the pulley I have now and re-install it with the proper torque settings and all that just so I can make sure it wasn't knocked loose at some point (which wouldn't surprise me...)

The pulley is bolted to the water pump. So the only way the pulley would wobble without it being the pump, The bolts on the pulley would have to be missing or really loose. Or the pulley is completely bent. So more then likely you will be changing out the pump.

I'm looking at the mechanics' manual and apparently the pulley is bolted to the shaft that drives the water pump impeller, from the looks of things the pump would have to be pretty wrecked to wobble around like that, I suppose its possible but considering that its summer and I haven't overheated... at least, as far as I know, all I have are idiot lights that may or may not work.
What causes water pump failure? Bad bearings?
Is it worthwhile to remove the pulley and replace it or should I just go for the whole water pump? The pump costs about $45 it seems but I'd prefer to save the money if I can.

Ah, so belt tension can cause this? My belt is on pretty tight right now but still follows the "flex one-half inch" rule. I was frustrated because before, I could hear it momentarily slipping and headlights dim slightly if I turned on the heater.
Hopefully I can get to NAPA some time, I think they are open 11am to 2pm minus lunch break and tea time. Ha.
