Unrelated to fanance kinda.. Volvo S80 2.9 Alternator change

Just got my first European car Swiss to be exact. I have had Japanese and Korean so I am familiar with metric bolts. Never had a car over 4 cylinders until now though. I find I prefer the expendable nature of small 4 cylinder economy cars as I am so delicate with this one. Its a used Volvo S80 2.9 non-turbo. Recently the car would not stay running unless it was connected to another running vehicle. I took the battery to Autozone for a free test and it passed. Going through the forums and asking for help eventually got the alternator out for a free test and it failed. So that was the problem. The dealership wanted over $600 for the alternator and I got one from Ebay for $50 plus fees. Popped it back in and got back on the road. This is unrelated but I found the instructions on the forums to be somewhat inaccurate.

1. Disconnect the battery terminals(10mm and 12mm bolt)
2. Remove the cover from the computer box and the outer cover
3. Use a flat-head screwdriver to remove the plastic cap from the tensioner pulley.
4. Rotate the pulley nut now visible clockwise(14mm bolt)
5. Pull the belt off while releasing the tension from the belt.
6. Remove the plastic cap from the positive terminal on the alternator(13mm)
7. Remove the three bolts from the power steering pump(12mm)
8. Remove the 2 bolts that are at the top of the AC compressor(12mm)
9. Loosen the 2 bolts at the bottom of the AC compressor(12mm)
10. Remove the bolt holding the top of the alternator(12mm)
11. Remove the water hose at the end to the Radiator(7mm)
12. Remove the bolt from the dipstick hanger(10mm)
13. Pull the alternator out(hard) Be careful not to break anything while forcing it out.

Autozone will sell you a cheap alternator about $190+ without a pulley. You have to remove the pulley by spinning the bolt clockwise(i really mean clockwise)(24mm)with an impact wrench. Or a 10mm star tool with a special open ended 24mm wrench. There are 2 different amps available. 120A and 140A so have it handy when you visit the parts store.

Or just buy a used alternator on Ebay as the dealership will charge 500 for the alternator unit only. I got one from Ebay for $50, and it came with the pulley.

Also you could simply order a regulator(Bosh or Chinese generic) which comes with the brushes inside for $20 to $50. Swap out the old regulator and the alternator will act like new.

Photos pending.

Now for something more related. Buy shares in Pep Boys(PBY) hold and sell at the end of spring. The summer compels long distance trips, dates, racing, car shows, car sales. Its also income tax return time.
