My new to me Saab 900 SE Turbo is a beautiful ride. One day I was 'passing' a lady on a surface street and I heard a pop. I didn't lose any power so I wasn't too worried. There was a slight rattle that got progressively worse as I drove. So I got it home and popped the hood. Nothing visible to the naked eye. I put a torque wrench extension bar to my ear and I checked the power steering pump and the valve cover, but neither was the source of the noise.
The noise got so bad I was forced to take the car to my mechanic, who told me it was the water pump and "don't drive it more than you need to cause it's fixin' to go out on you.' Thirty minute ride from the mechanic to home, where because of the cost - $508 + tax, I was going to do it myself. I stopped at the mall which was about halfway. Once I started the car again, there was a problem. A loud squeal and a warning tone. My idiot lights told me there was a problem with the battery. I popped the hood and the serpentine belt wasn't moving and the water pump pully was canted at an unnatural angle. Bad news.
I decided to chance it and make the rest of the drive. No alternator, no power steering, no heat and most importantly, no coolant. Two minutes from the house, there was a giant boom under the hood and a cloud of antifreeze behind me. I finally make it home and pop the hood to let the engine cool off. Very close call.
