So even following the walkthrough, I've gotten stuck on fixing the water pump. First of all I could only find the leaking pipe over the crates. I could not find any other problem, neither I have another place to use the wrench. I just know that I cannot get the key from the old lady until I fix it. I am missing anything?

Once you fix the first leaky pipe, go turn the wheel to the left again. Go back around to the front, grab the left-hand crate and pull it out. Now you can get to the new leaking pipe and fix it.
