Replace Corvettes O2 Sensors

This would be a far emptier parking quantity without working Oxygen sensors.


Plug the wiring harness back into the O2 sensor. GM harnesses only go on one way, so it's hard to make a mistake here. Corvettes produced in or after 1996 account one Oxygen sensor in the exhaust manifold and another after the converter.


Instructions


1. Lift the front of the automobile with a floor jack, and secure it with jack stands. You should particular charge to lift the motorcar by approximately six inches to access the Oxygen sensors.


2. Finger the headmost Oxygen sensor, which Testament be either on the drivers' side exhaust manifold or approximately three inches outside from it on the exhaust conduit. Newer Corvettes include an Oxygen sensor on Everyone manifold. Determinate the moment O2 sensor on the exhaust pipe just past your catalytic converter.


3. Unplug the wiring harness connector from the O2 sensor you wish to replace. You may need to use a flat-head screwdriver to release the locking tab on the harness.


4. Slip your specialized O2 sensor removal socket (available at your local auto parts store) over the O2 sensor, allowing the wires in the top of the O2 sensor to slip out of the slot in the side of your socket. You can use an open-ended wrench to remove the after-cat sensor.


5. Connect your O2 sensor to your ratchet using whatever arrangement of extensions and U-joints that you need. For example, to receive around the front crossmember you may need to use a socket connected to a U-joint, connected to a three-inch extension, connected to another U-joint and then a six-inch extension. Turn the ratchet or wrench counterclockwise to remove the O2 sensor. This might take some elbow grease if your car has a lot of miles on it.


6. Put a pencil eraser-sized dab of anti-seize compound on the threads of your new O2 sensor. You'll thank yourself for it when you need to replace the O2 sensor again in 10 years or so.


7. Screw the new O2 sensor into the hole where your old one came out, turning it as tight as you can with your fingers. Tighten your O2 sensors to at least 30 foot pounds using your wrench. In practical terms, it's almost impossible to strip an O2 sensor bung with basic hand tools, so just grab a handful of wrench and pull.


8.O2 sensors (very notorious as "Oxygen sensors") are essentially temperature probes. Air/fuel ratio has a regulate appositeness to exhaust Gauze temperature: A fuel-rich ratio Testament cook up the exhaust colder, and a fuel-lean alloy Testament assemble it hotter. The vehicle's pc development extrapolates from exhaust Gauze temperature to cause child changes in the fuel injection and ignition office cycle to optimize for influence, fuel economy and engine longevity. Chevrolet Corvettes produced before 1996 posses solitary one Oxygen sensor on the exhaust manifold or in the main connected to it.
