Call me retarded, but im at my wits end with this fucking thing.2001 GMC Yukon Denali (LQ4 engine)This fucking sensor defies all logic. I can not find a single tool anywhere that works. >1-1/16th socket: too shallow>AutoZone OPS 1-16th socket “for GM vehicles”: too shallow>1-1/16th wrench: too wide to be able to turn within the casting of the block>order deepwell 1-1/16th socket: STILL TOO SHALLOWOkay you son of a bitch>grind the “meat” off the wrench with an angle grinder to give it more room to turn within the casting.>just fucking slips off every timeSeriously am i missing something here? Am i a God damned retard? I can see why GM switched to the version with the smaller plastic female end in later model years, because this is fucking impossible with the engine OUT, i couldnt even imagine doing it with the engine in. But what were GM technicians doing in 2001???I cant find a single video or forum post addressing this issue with this specific style of OPS. Ive looked for specific sockets, even asked ChatGPT to disregard any results that arent specific to the 2001 model year. No useful info so far.I also thought about taking the plastic part off, installing the metal part then, reinstalling the plastic part, but it doesnt seem to come off, and i dont wanna risk breaking a $100 part if i can help it. What i do d/o/ here?
have you tried an adjustable wrench and just do it inch by inch?Or one of these fuckers
https://www.lislecorp.com/specialty-tools/oil-pressure-switch-socket-24 Usually lisle sells good tools, is that too short?maybe this one?https://www.ebay.com/itm/336154021099?chn=ps&google_free_listing_action=view_item&srsltid=AfmBOoqrq3Lf2DDF-iOnxUyruAce1NPjRpm62-34O4VZDpor1ec6t8bukvo
Why not just use the ring spanner end of the wrench? Am I missing something here?
>>28624923I did try an adjustable wrench, but ran into the same problem as i did with the 1-1/16ths wrench. Too wide to turn. But no, i havent tried an O2 sensor wrench. I have one for the O2 sensors on that same engine, but its 22mm whereas the hex part of the OPS sensor is (when converter from inches) about 27mm. But ill see if someone makes a 27mm O2 sensor wrench. Thanks
>>28624936make sure you measure that its deep enoughI'd honestly try pic related first
>>28624942https://www.youtube.com/watch?v=8WIXkvq7bLY&ab_channel=TRQit's in a shitty location and the block may get in the way of anything but a socket.
>>28624902Just pull the intake off and get all the room in the world to figure it out, it takes like 15 minutes. t. have changed them both ways
>>28624936In the Lisle one it shows the sensors its supposed to work on, one of which looks like my sensor, but the socket itself looks no different than the one i got at AutoZone? As in, the correct size for the hex, but not long enough to accommodate the plastic part of the sensor. Same goes for the eBay one.>>28624942Tried that too. If youre standing at the back of the engine looking forward, in about the 10 o clock position around the hole for the sensor, the casting is just slightly too tight to allow the closed end of the wrench to fit. I even tried shaving material off of that end of the wrench as well. No luck. I cant get it thin enough to fit. Its in my friends garage but i might be able to get pics tonight so you guys can see what im talking about
>>28624965actually here's an older one with your style sensor
>>28624965>>28624968Were you able to get a socket on it? I have the intake off already, but every socket ive tried so far cant accommodate the plastic part of the sensor, and every wrench cant fit because of the casting of the block itself.
>>28624975Do you have a new sensor already that you can test fit with sockets? The GMT900 one I did literally yesterday just needed the socket to be tapped down onto the sensor with a baby hammer, I just used my run of the mill 27mm impact socket.
>>28624993Well i tried to force the sensor into the socket by hand, but i didnt try tapping it in with a hammer. Might be a tight fit but i suppose its worth a try. Ill try tonight and report back
>>28624902I just did mine recently and used this socket. I had the stubby sensor but it seems long enough to accommodate those longer sensors. The actual mating surface on those sensors isn't very much so be real careful side loading the sensor with a normal tapered socket. It wouldn't take much to strip it then you're in a real world of shit. Also be careful if you're using swivel joints.
>>28624965Why's everything so big??
