Has anyone here replaced the O2 sensor on a 1987 Ford Taurus 2.5L?
I need to know where it is. I am using the drawing at
Also, is the "front" of the engine on the left as one stands at the front of the car, looking down?
Any other hints on locating the oxygen sensor?
I am helping a relative do this from afar. I've done it on my Honda Civic straight-4 engine, but the V-6 design of the Taurus is throwing me off.
