I need to replace the downstream O2 sensor and wanted to know which type socket would be best suited for it (long or short style). Any preferences?

 

I's been a very long time, (probably too long!). It would be long. I think I ended up putting a wrench on it. Guess there is also a special long socket that accommodates the wires. Somebody here should know better.

 

cut the wire off old one and use 6 point wrench to remove then install new one useing open end of wrench...

 

Would you get it hot and hit it with PB or something first?

 

I have the O2 sensor socket and wrench. All O2 sensors are 7/8" and prior to acquiring these specialty tools (available at any auto parts store), I used a wrench. Just undo the harness and slide the boxed end over the wires... Or cut the wires as stated above.

 

l use the wrench less chance of slipping and cracking knuckles there hardly ever in a great spot ya no
