Thought it would not be too bad looking at it. Loosen the idler and remove the serpentine belt (You can just move it off to the side to get it out of the way). You will have to take the 2 bolts out that hold the power steering pump and move it off to the side to get to some of the water-pump bolts. The Water-pump bolts are accessible but you will run into one snaffu. You will get the bolts loose, but I ran into one that wouldn't come out because brackets were in the way (Got the son of a gun out of the block but couldn't get the water-pump out) . I decided that I would not tear half the engine apart to get the last bolt out. It was one toward the front of the engine. I decided since the old water-pump was no good, I would use a pry bar and bend the bolt until I could remove it. The Water-pump housing cracked but I didn't care (it was garbage anyway). Now I had to figure out what to do about replacing the bolt. I grabbed some 5/16 threaded rod, a flat washer and 2 nuts. Measure the threaded rod in the bolt hole of the new Water-pump and make sure that you have enough thread to go into the block. The rule of thumb is at least one and a half times the diameter of the bolt. So if the bolt is 5/16 you want it to go into the block somewhere between 7/16 and 1/2". Install the new water-pump. When you get it in and get to that last bolt, double nut the end of the threaded rod,put the washer on, smear the threaded rod with sealant since it goes into the water jacket, and make sure it goes into the block enough to tighten it down. I have had the new water pump on the car for over a year with no problems. The car has close to 160,000 miles on it. I don't expect that this car will need another water-pump for the rest of its life but if it does, It will not be too bad to replace.

Disconnect your battery (make sure you know radio security code if you have one) Unbolt starter, lower it and remove wires. Some twisting and turning may be required to get it out. Reverse process to install.

Not too bad. Loosen water pump pulley bolts then remove belt. Remove pulley and remove all of the pump bolts.

Too complicated to explain here...buy a Chiltons Manual at Auto Zone or NAPA $25...not too bad of a job but you should have a thorough knowledge of tools.
Good Luck

Place Jack under engine with wood to hold it up. Remove uper engine mount(leave loose in engine compartment. Loosen pulley bolts. Remove belts. Remove alternator bolts and lift out of the way for easy access to power steering bolts. Remove 2 power steering bolts using access holes in pulley. You should be able to accessall of the water pump bolts now by moving things out of the way as you go. The two larger bolts toward the radiator can be accessed through the two holes in the motor mount ( you will need a short socket on a 1/4" drive rachet). You should be able to get the pump off now. Installation is much easier than removal.
