Babypig

Well i got the tell tale red leakage at the water pump which means I'm gonna dig into this baby one more time. My question is , do I need to remove the crank pulley to get at the bottom bolts of the water pump or can I leave it on and still get around it. I know that the timing cover has to come off and i was wondering if the idle pulley are a bear as well. 1990 4runner 3vze v6. Anyone got any pointers?

Thanks in advance
Steve
