There are a lot of issues in your car that neither you can fix nor ignore but to go to an expert. However, an O2 Defouler can be the best option to avoid all the problems and be your savior.
So, what does an O2 Defouler do? If the engine check light turns on, O2 Defoulerit can help to keep it off. It also keeps the O2 sensor away from the exhaust gas, so it gets enough time for O2 checking. Thus, it protects the O2 sensor from direct heat and the environment from harmful gasses.
That’s not the end. In this article, you can find some related information about the O2 Defouler and the installation process. So, read on and stick with us.
What Does an O2 Defouler Do?
The primary function starts of O2 Defouler is when the O2 sensor stops working. O2 defouler functions are:
- O2 defouler gives space to the O2 sensor. As a result, the O2 sensor can not read directly from the exhaust system
- It helps to maintain the check engine light off
- The O2 Defouler keeps the O2 sensor out of the exhaust flow
- It helps to count correct non-combusted CO2
- It helps to reduce the excess burn of fuel and produce more power. If the O2 sensor senses a lot of O2, the ECM commands the injector to spray more fuel for a proper mixture. It leads the O2 sensor to count less O2 from the system
- It helps avoid open loop
- O2 sensor with a Defouler lasts long because it is away from the heated gas
Overall, an O2 Defouler is a life-changing instrument. As it prevents the burning of excess fuel, that means it reduces the rate of harmful gasses formation.
How to Install an O2 Defouler?
People who are suffering from the check engine light turning on follow a common solution. That is to install an O2 Defouler. It helps to reduce all the problems related to exhaust pipe installation. Follow this process to install it yourself:
Step 1. The O2 Defouler comes with some fittings. What you have to do is to adjust them and prepare the defouler for installation
Step 2. The washer should encircle the part which is supposed to fix the exhaust manifold
Step 3. Put the spacer on the same part inside
Step 4. Place a retaining pin that comes with the defouler into the groove between the pipe and the spacer. You can take the help of a small alligator nose plier
Step 5. Now go underneath the vehicle. Lose the downstream O2 sensor from the exhaust system with the help of an adjustable wrench. Unscrew the O2 sensor
Step 6. Apply a little anti-seize to the O2 sensor
Step 7. Now install the narrow part of the O2 defouler in the exhaust pipe. Tighten it up with an adjustable wrench
Step 8. Twist the O2 sensor several times reversible before screwing another part of the defouler with the O2 sensor
Step 9. Screw the O2 sensor with the O2 defouler by hand. Then tighten it up with a wrench
Step 10. Keep the extended O2 wire underneath the shield
That’s how you can install an O2 defouler or an O2 sensor spacer. That can help you to get rid of problems related to the engine check light.
Conclusion
That’s all about today’s topic about what an O2 defouler does. O2 defouler helps the engine system to run properly. Any unwanted trouble related to fuel combustion can be handled by it. O2 defouler or spacer reduces the release of gasses like CO, Nitrogen, and CO2 in the atmosphere.
However, engine lights can be checked by other techniques. But checking with a spacer is the cheapest way. Nevertheless, you should be careful while installing it. Installing the upstream O2 sensor can cause wrong readings of reduced O2. That can cause problems.
