Being new to turbos, I was having a hard time relating the topic descriptions to the actual unit while looking at it on the car. I couldn't find a diagram that did a good job of identifying the various components anywhere - not in Bentley, Haynes (240 or 940), Brickboard FAQ, Mitchell CD (it may be in the Volvo green manual, but I don't have that).

Anyway, I took it upon myself to make my own. Hopefully other turbo neophytes like myself may find it helpful. (I did steal the photo from John Sargeant's "Turbo Model Identification - photo file" in the FAQ).



1 incoming air from filter
2 compressed air to intercooler
3 vacuum from intake manifold (drives CBV)
4 compressor bypass valve (CBV)
5 hose with compressed air driving wastegate actuator
6 wastegate actuator
7 wastegate actuator rod
8 wastegate shaft
9 oil supply line mount point
10 coolant drawn into turbo from overflow hose split
11 coolant supply line
12 coolant outlet
13 water pump draws coolant here via lower rad hose split

The only things not clearly shown here are where the coolant supply line connects (180 degrees from coolant outlet connection) and oil outlet line (180 degress from the oil supply line mount point).
