Thanks to everyone for the tips - I've picked up a tensioner and borrowed some tools from a local mechanic, and I've now run into my next problem with this job! Does anyone have any tips on getting the belt pulleys off? Everytime I try to break loose the bolts on the water pump and power steering pulleys, the pulleys keep turning against the belt (which, I assume, when tensioned is ordinarily sufficient to keep them from moving). I've sprayed some liquid wrench (on the bolts, not the belt), to no avail...

thanks,
anthony
