1989 Volvo 740GL O2 Sensor

[pmharrington]

Hi,

Wondering if somebody could give me a quick how-to for an o2 sensor replacement. I've been told it's dead easy, but can't even seem to find the damned thing.

I don't see it where I'd expect to, on the manifold, but I've only been looking from the top. Should I be getting under the car?

I have a replacement ready to go, just need some direction to get started.

thanks!

02 Sensor is screwed into the side of the catilytic converter and cable runs up the passenger side of the firewall where it connects close to the spring for the hood. It's easy....disconnect the sensor from the cat and then tie the new conncector via wire tie on to old sensor and pull cable up to the front of the car.....follow the wire to make sure you have it removed from the clips that hold it in place. I did it this past febuary hardest thing to do was get one side of the care up so I could fit under car to do it.
