I was going to do my crank seal today but, when i went to take the fan off i noticed that there were no bolts on the water pump pulley to grab onto, just 3? little holes. It looks like there is some sort of cover on the pulley. Is it a cover and if so how do i get it off? Also, the autoparts stores around here do not have a tool for the seal, so should i just use a screwdriver to pry it out?

Thanks
