Show how to change water pump on 1993 Mercury Cougar
First of all this is a royal pain.
You cannot remove the fan shroud without removing the fan clutch, so, remove the fan clutch and fan shroud. You will have to remove the four bolts holding the fan clutch while reaching under the shroud. If you have lost the sticker that shows how to run the serpentine belt, now would be a good time to draw yourself a diagram, or take a picture. Now you will see that there is a bracket that goes from the front of the Power Steering pump to the right side of the water pump, there is no way around this that I could find, go buy or borrow a pulley pulling kit (If there is an autozone near you, they will loan you one if you leave a deposit equal to the price, in my case $35 bucks, when you take it back unharmed, you get all your money back including tax)
Pull the steering wheel pump pulley, and it will reveal 2 bolts holding the bracket. Now remove the serpentine belt and unbolt the water pump. It has about 8 bolts, and thanks to the Ford engineering geniuses, they are almost all different sizes, ranging from 13mm to 19mm, you will need deep sockets because a couple of these are nuts on studs. Remove the power steering bracket, then the hoses (one on the bottom, two on the top) and then the water pump. scrape clean the engine side of all the old bits of gasket. put a light film of form a gasket, or some such silicone stuff to hold the new gasket onto the new pump (pump side only, the gasket by itself should seal on the engine side, don't over do it). put the new pump on and replace the bolts (alternate so that you tighten them evenly. Put back everything you took off. Now would be a good time to replace hoses and the belt if they are at all worn. Now curse the ford engineers one last time, and you are done.
