How to Replace a Catalytic Converter on a Honda CR-V

If you own a Honda CR-V, you might be accustomed to the check engine light turning on and the warning that the catalytic converter needs to be replaced. The good news is that even a novice car owner can complete this repair. Although some components will need to be removed from underneath the automobile, the operation is often relatively simple. Your CR-catalytic V’s converter reduces pollution by filtering out hazardous exhaust gases from the engine. The exhaust gases are oxidized and rendered harmless by being converted into CO2 and water vapor in the system’s ceramic honeycomb tubes, which are coated with a variety of chemicals.

How to Tell if a Catalytic Converter is Bad

Having a qualified mechanic examine your catalytic converter is the simplest way to determine for sure that it is broken. If you’re going to replace it, you might as well replace the one that is undeniably damaged rather than take the chance of using a defective one. You can ask the emissions tester to examine the converter during an emissions test, or if you’re inquisitive, you can check it yourself. Make sure the engine is cool first. Remove the exhaust pipe next using a wrench, then inspect the catalytic converter to determine whether it has corroded or become discolored.

What You Will Need

Wrench – A rag – Paint thinner – Penetrant fluid – Safety goggles for eye protection when cutting and welding – Protective gloves – Structured wiring for the catalytic converter’s rewiring – A switch to reroute the exhaust gases. – A helper in the event that the repair is challenging to do alone.

Step 1: Disconnect the exhaust

You must first unplug the catalytic converter’s exhaust first. This is accomplished by removing the bolts holding the catalytic converter in place. You might need to call someone to your home to assist you in entirely removing the catalytic converter if your vehicle has an aftermarket exhaust system. It would be preferable to totally remove the damaged catalytic converter and weld a new one in its place. If the catalytic converter is totally removed, this is significantly simpler.

Step 2: Remove the catalytic converter

The catalytic converter must then be taken out of the vehicle. Once more, if you have an aftermarket exhaust system, you might require assistance with this step. You must first remove the bolts holding the converter in place before you can separate the wires that connect to it. A mechanic can help you if you have any questions about how to do this.

Step 3: Install the new catalytic converter

You can now install the new catalytic converter after removing the old one. Make sure the new converter is correctly positioned first. Next, fasten the nuts while tightening the wires. You’ll need assistance mounting the converter to the vehicle if it has an aftermarket exhaust system.
