Volvo Repair: Oxygen sensor, oxygen sensor, volvo s70

Question
I recently purchased a front oxygen sensor for my 1999 Volvo S70.  I would like to know the easiest way to get at it to replace it.  It appears to positioned in a tough place to access.

Answer
Jim, any particular reason why you are wanting to replace it?  Was the car scanned and diagnosed?  Having a lift would be best but the best way is to lay on the engine and with a small screwdriver, easily ory up on the connector and it will release the sensor connector.  Now jack the car up and use a 7/8 wrench and remove the sensor.  Not sure if I recommend you trying this.  Roger
