Re: Oxygen Sensor Replacement - Problem
First, thank you for your service. Failed to mention that in a previous post.
Second, If you pull the hoses off the PS pump, you will need to catch the fluid.
If you pull the hoses off of the AC, you will lose the freon and have to pay a lot more to get it fixed.
You shouldn't need to pull anything except the leads off of the O2 sensor.
The one closest to the radiator should be bank 2 sensor 1, bank 1 sensor 1 should be in a similar location near the fire wall on the exhaust manifold. If you follow the exhaust far enough, sensors 2 will be after the catalytic converters, bank 1 on passenger side, bank 2 on driver side.
Got to reading around and it look like the best angle of approach for your car is from below. If you have to put a socket on it, there's one designed for O2's that have a slot cut out for the wire. It's worth having. On the new sensor, apply a thin coating of antisieze to the threads, I recommend the copper type rather than the silver as it takes the higher heats better. Just remember to try to keep the antisieze off the probe.
