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.

Local car parts stores, and some libraries, have sets of repair manuals for sale or for checkout. These go by make and model and years. These will walk you through this job. God bless your efforts.

If it's like my 1990 Cadillac Deville, the steering wheel along with the air bag will have to be removed to gain access to at least 2 of 4 bolts that hold the steering column tight.

A technician can tighten 2 of the 4 bolts in order to make the steering column as tight as it should be. It's not necessary or possible to reach all 4, believe it or not.

That's the way GM steering columns are, I guess.

if you open your trunk and look in the far right of the trunk you will see a bulge carefully remove the carpeting out of the way and you will see a lid with five screws remove them and tada you have foubd your fuel pump easy as pie to find and replace also althoug unconfortable

In 97 GM did wire it to run continually. But not hot air. Most likely mode door is stuck or control faulty (vacuum or bodin cable)

depends, do you have receiver - dryer or accumulator system? Most likely you have an Orifice tube located close to accumulator inside aluminum line

Replace the blower motor

Is it throttle body or port fuel injection?
