I've got a 99 5.4 2wd. I need to change out all four O2 sensors. What is involved in doing this? Is it easy to do? Can I access all four easily? Who has the best prices?

Thanks

 

I need to change a right rear O2. My service manual covers 97 thru 03 trucks and the O2s look accessable enuff from the photo. I bought 2 different removal tools and a can of PB Blaster. I used a shot of it to remove my fan and that stuff is great.

 

Its pretty easy. The hardest part is disconnecting the electricial connectors. They are hard to get to, if i remeber correctly one of the connectors is on top of the tranny. Other than that just take the sensor out with a wrench and there you go. They also make special sockets for these that have a slot cut in the side so the wires can stick out.

 

Good news. I don't have to change the sensor. I still bought the tool.
