Anyone know where the air pump on a 98 V70 is located ? Is it belt driven or electrical?

I took the car in for a timing belt change and a 60K checkup ( has 66K on it ) and they found the air pump inop ... $ 660.00. The tech called and said the PCV valve was broken and the distributor cap busted and this is why the car was running so bad ... problem is the car wasn't running bad, at least not to me, maybe the computer said that it was running bad but I didn't think so. Anyway I get the car back, air pump still inop, and the front headlight still wasn't fixed so I decided to take a look myself. The fastener that holds the bulb in place was loose so I snapped it into place and this resolved the dead headlight problem .... but ... in the meantime I had the car running in the garage because I had the lights on and didn't want to run the battery down ... I noticed the car surging and producing fumes ( never did that before .) Bottom line is the car seems to run worse than it did before I took it in. Also someone identified a place to get a haynes manual for the V70 ... could that person repost that info ... I did a search but no joy
