What is the best way to remove the passenger side O2 sensor on a 95 Lt1? Driver side was a breeze but the passenger side is hard to get a wrench on. Any special wrench required? Thanks
I am looking to replace both of mine on my 93 LT-1. If I can get to them this weekend, I will let you know how it goes. If you figure it out before I do let me know.
I ended up having to buy a special O2 sensor tool. You slip it onto the sensor and it has an extension bar with a 3/8" square drive that allows you to use a ratchet wrench from underneath the car. Here's a link http://buy1.snapon.com/catalog/item....&group_ID=1448 I ended up getting mine for less that $15 on eBay.
Mine cost me about $15. It makes the whole job almost a snap. Well worth the few bucks, IMO .
P.
With that tool I was able to remove my pass. side O2 from the top side. Just used several extensions to make the reach. It also allows some good positioning to apply a little torque for removal.
the best advice I ever got from one of the guys on this Forum for O2 sensor removal from my '95 LT1:
7/8" open end Craftsman "Stubby"
You have to remove from underneath though. With this tool, I can get them out and back in in less than 10 minutes. Be sure to disconnect neg. battery cable, as you may touch the Positive terminal from the starter motor, and get a nice jolt....
