Eradicating the Oxygen Sensors
Oxygen sensors are used to measure the oxygen content material within the exhaust gasoline. They’re positioned within the exhaust manifold or exhaust pipe. To take away an oxygen sensor, you will have the next instruments:
- Wrench
- Socket
- Oxygen sensor wrench
First, find the oxygen sensor. It is going to be a small, spherical sensor with a wire popping out of it. Subsequent, disconnect the wire from the sensor. Then, use the wrench and socket to take away the sensor from the exhaust manifold or exhaust pipe. Watch out to not injury the sensor or the threads on the exhaust manifold or exhaust pipe.
| Step | Directions |
|---|---|
| 1 | Find the oxygen sensor. It is going to be a small, spherical sensor with a wire popping out of it. |
| 2 | Disconnect the wire from the sensor. |
| 3 | Use the wrench and socket to take away the sensor from the exhaust manifold or exhaust pipe. |
Putting in a Substitute Converter
As soon as the previous catalytic converter has been eliminated, a brand new one might be put in. The method of putting in a substitute converter is as follows:
Step 1: Collect Instruments and Supplies
You will have the next instruments and supplies to put in a substitute catalytic converter:
- New catalytic converter
- Wrenches
- Screwdriver
- Jack and jack stands
- Gloves
