Best way to change O2 sensor/ECT sensor?

[99gtxws6]

For the O2: Go in from the top or from underneath? If I unbolt the dogbones could the motor come foward enough to get back there with a wrench?

And for the ECT: Do I need to take the exhaust crossover off to get to it? Looks like it's the only way to get there with a socket.

02 get an 02 socket and go from the top
ect take off the left dog bone bracket then use a 19mm socket.

spray the 02 sensor with penetrating lubricant about 2 hours before, they can be a sob to get off

No need to move the motor forward? I can get a wrench on it now but there's no room to turn it.

if your set on taking it off and just replacing you could buy the o2 socket which is a 7/8's and use an extension, or cut the pig tail and use a 7/8 socket but then I dont know if you would have enough room to get the new one in using the wrench method

You need one of these, like 10-15 bux at your local auto parts store, buy one, youll need it later at some point or another

yeah that is the 02 sensor socket I was referring to. its really your call OP on which way you would like to get it off.

you can pull the motor forwards a little more, but the o2 sensor placement just sucks in general. you kinda just have to get in there and have at it.

That socket would not fit on my o2, the sensor was too fat to fit inside of the sleeve. I had to use an open end socket for mine.

You bought the wrong one then.

They were both the same size, but the inside of the socket was a little too narrow. Doesn't really matter though as the other socket worked just fine.

Truth^ One of our techs has 2 different ones, both the "same" size, but one wouldnt work to remove my 02 sensor when we did the motor swap... dunno why but it happens
