simple question for those who took off the SENSOR 1, the precat, the A/F, not the O2 after the cat.

the 02 has that shield around it,plus u need an open socket for the wire, well what about the sensor 1? its open, unplug the wire put a closed end wrench on it, im just wondering what size it is, as i'm gonna go to the parts store.

maybe its the same as sensor 2, but i dont even know the sensor 2 size, please someone let me know if u do know.

My sensors were 23mm

forgot to mention that mine is HR, but dont think that it would make a difference in the sensor size. Thanks mate, gonna go get a 23mm wrench

Get an O2 sensor socket. If they are rusty or too tight you can round them off really easily with a wrench.

well i got a wrench already(
the positive is that i now have a shiny wrench

Cant you take it back and exchange it?

Cookiezor

well, i just went and tried the wrench, and honestly i think its a piece of s h i t wrench. its from oreilly called Power Torque. and the sensor said 22mm, so i got 22mm wrench, and its either the wrench is **** ( not precise) bc that thing has a play in it, or the sensor is 21 mm. tomorrow i ll go and measure the wrench at their store. if its the wrench i ll get my money back, and get a socket, although i'm now iffy of buying anymore sockets from them( i have a few, and they have maybe a small play in them).

i used to have good tools, but my dad took em for his farm, and now i gotta buy new ones, and there is no store close by to get good tools from

Tools are the best investment you can make.
