JIvers Posted September 27, 2012 Share Posted September 27, 2012 So can someone tell me how to put in a new oxygen sensor on a 1989 Chevy 2500? I don't think it matters for this, but it has a 4.3 V6 in it. The Service Engine Soon light comes on in my '89 Chevy if I drive it at highway speed for a few miles. The motor runs about as well a twenty-three year old motor with 166,000 on it can be expected to run, so I wasn't too worried about it. I got the issue checked at an auto parts store, and all it needs is a new O2 sensor. It looks like I can get a new sensor on-line cheap, but I need to know just how to put it in. It is supposed to be easy, but that doesn't help if I don't know where to start. I'd rather do it myself, and fix it so my gas mileage isn't quite as bad. Plus, if I let it go and the Service Engine Light comes on because there is a real problem, I'll just ignore it if I don't fix the O2 sensor.
