How to change o2 sensor. Bank 1 Sensor 1 on a 2003 chevy sliverado

This will show you how easy it is to change out your o2 sensors in your vehicles. Just go to Autozone. They can run a free computer dignostics check. they will tell you what the problem is. Buy the part from them and you are good to go. You will need a special oxygen sensor socket. You can buy it at autozone. Or at Harbor freights (cheaper). (in my case the socket just would not work. i had to use a old fashion wrench) Turn the vehicle on for about 5 minutes. Let the exhaust get nice and hot. Spray some wd-40 on the oxygen sensor fitting. let it set for a minute or so and start working it loose. Repeat the process for stubborn oxygen sensors. once removed. attach the wires. disconnect the battery for about 5 to 10 minutes. this should void your check engine light. Oxygen sensors are important. they help with your gas mileage. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to.

@MNBLAZER07 CUAL WIX !!! K &N PAPA!!!  THE TROCA BRINGZ THE BREAD HOME SO YOU USE THE BEST STUFF . NO CHINGADERAS.

@muncleike SOUNDS LIKE YOURE USING THE WRONG SOCKET MY FRIEND OR PERHAPS YOU NEED TO SPRAY THAT O2 WITH SOME PB BLASTER BEFORE YOU TRY TAKING THAT O2 OFF

[grneyzX3]

@ltsgoyanks LMAO!! DUDE SOUNDS LIKE YOU JUST WANT TO BURN SOME SHIT BUT ITS COOL WITH ME ,WHATEVER ROCKS YOUR BOAT!!LOL

@grneyzX3 Yeah, I totally agree that would be the safest method!!! Some cars in the NorthEast and Utah and CO that are subjected to harsh Winters and salted roads(still), may have to use the torch to get it out safely without damaging the exhaust manifold or RUSTED exhaust pipe. Pb Blaster is some good stuff! I recommend trying that first for sure!

@ltsgoyanks DUDE JUST BUY A CAN OF PB BLASTER ,SPRAY THE O2 TAP IT A FEW TIMES , RE-SPRAY IT AND WAIT 10 MINS BEFORE ATTEMPTING TO PULL THE SENSOR . PIECE OF CAKE.

@wow14willywaller yes. I have a 2001 Chevy Prizm and I'm supposed to be getting 29, and I'm getting high teens - low twenties. Just go to a local Auto Parts store and they can run a free diagnostics on your car and tell you what's going on.

For Stubborn 02 sensors, you can use a propane torch (of course be weary of gas tank/lines) and heat the exhaust pipe as close to the sensor (without heating the sensor!!!) as possible to expand the metal. remove heat source and very quickly remove the sensor before the metal cools off again(2 people is best).

I know common sense says the hole will get smaller as metal expands, making it more difficult to get out.. but the hole actually expands, making it easy peazy to get out the sensor.
