need help replacing water pump
 

hello, I have a 1994 Mazda B3000... which is the same as Ford Ranger V6... I replaced (had a mobile mechanic replace) the water pump 2 years ago and now it's leaking about a gallon of coolant a day... I replaced ALL the hoses... heater, radiator etc... as replacing the water pump is a huge pain in the butt... I've removed the a/c compressor and now I am trying to remove all the crap off the engine to get to all the bolts that hold on the water pump but need to remove the assembly that holds on the power steering pump, Idler and tensioner pullys... I have removed the front bolt and the rear one but there is one more that I just can't find... can anyone here help me? thanks...
