How do you replace o2 sensor?

shouldnt be. should just need a socket wrench and a combination wrench. now they do make special sockets for removing them but its not worth the money. i got both mine off with PB blaster and a combination wrench.

Very good chance the bolts for the heat shield are going to break anyway.

okay looking at that diagram your gna have to remove the front cover ?
or can you just access it underneath the car.?

all you need to remove is #4
and the 3 bolts

unplug and unscrew the sensor.
then
screw in the sensor with Anti-Seize then plug back in.


And put the Heat shield back on.
