Hey guys

Please help, yes ive read every page that has somthing to do with 02 sensors on this site.

This is my situation

On my Cefiro, i pulled off the dump heat shield and left it off. This caused the WIRE AND PLUG for the 02 sensor to be melted to pieces. The whole loom was roasted as well, leaving only about 10 cm of loom near the chassis.

I have ordered a new 02 sensor alredy picking it up this afternoon and ive got a 3 pin connector as well.

Now my problem is.

What sort of wire can I use to extend the 3 wire loom, what is the sort of Heat proof coating I put over it and also lastly

HOW THE HELL CAN I REMOVE THE 02 SENSOR? I can get a Open ended 22 over it, I can get plenty of leverage, AND ive even Soaked it in Rost Off (angriest version of WD40/Penetrene) and used all my strength but the thing wont budge.

Am I just weak or is there another way - I cant get hold of a 02 socket (Repco/autobarn/supercheap) dont have one - so any other suggestions?

Hope you guys can help

Regards

Kim

it's not easy getting off.. you can run the car without the o2 sensor for a while if you need to. Maybe try undoing it when the dump is warm. Obviously not fuse-the-fingers hot, but once it's started to cool down to touchable levels.

just zip-tie the o2 plug to the firewall, will stop it flopping down and melting in the future. That seems to have worked for me. If you want to insulate it (say if you run at regular full boost levels), I'd use some of the stuff you use to insulate turbo lines.

Maybe have to take the dump off to get enough leverage? that's what I had to do with my original dump pipe to get it off as a last resort.

where would you buy insulative stuff, gordo?

will places like supercheap have that?

Try Revolution racegear, there is one in moorooka in bris..

Either that or a specialist hose shop may have it to insulate fuel lines, etc.

Had the same problem before... surely it was a biatch to take off. O2 sensor wrench was way too expensive ($45 for a socket... forget it).

So, went to Bunnings to the plumbing section, got some sort of wrench for plumbing / piping, octangular in shape, fits perfectly. Used a long stainless steel rod along the wrench for leverage, and half a can of WD40 later... hurrah!

I hope that helps..

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
