does anyone have an idea of what size the tool for the oxygen sensor is? I bought one thinking it was 22mm,but it is to large and is just rounding off the nut ,21mm does'nt seem to fit...is the Lexus ,Toyota company that sly that they would design this so you & I would have to buy a tool from them???any idea were I can find this 'tool' ,and what size would be great .
thanx;Dean




thanx size is 7/8 inch ,for some strange reason the o2 socket that I purchased was 22mm in a 7/8 th labelled package ..

 

I just use an adjustable crescent wrench on it.

 

yup, same here.

 

heh there is no way to get a cresent wrench in that space,I can just get a socket in there ! I just might have to try and rip out the manifold to get some leverage on it what a nightmare !!

 

if you have room to get a rachet in there, you should have room for a crescent wrench. Im assuming this is an sc4 since the sc3s should have no trouble at all. Try jacking up the car to get to it from underneath.

 

beleave me the only way to get to those suckers short of putting it on a hoist ,is to stick a jack under it and remove the wheels! I 've been strugling with the last one [ passenger side ] for two weeks!

 

7/8 fits it too

 

well I finally wresled that &*#%@ o2 sensor out with the propper sized [7/8 ths ] o2 socket and hopefully that will keep the check engine and trac lights from coming on . thanx guys !!
