Volvo Repair: radiator/oxygen sensor replacement, oxygen sensor, sensor replacement

Question
Have a 2000 S70 GLT SE/Turbo/auto w/99k miles. I have replaced several radiators before on V8s, and recently both 02 sensors on a 1998 Contour 24v V6. How challenging is this to do both... on my Volvo, before I order the parts?

Answer
Paul, To put it mildely, I dont even like to so them.  Since its a Turbo, its worse.  Both the rad and the intercooler have to come down while  the condensor hangs.  Its best to do it on the lift.  You will never be able to do it on the ground unless you use ramps.  02 sensors not too bad to do.  Roger
