The part of your Honda CRV’s exhaust system that is in charge of filtering out dangerous gases before they leave the tailpipe is the catalytic converter. The catalytic converter may not be able to eliminate these dangerous gases from the exhaust stream or degrade CO, HC, and NOx pollutants if something goes wrong with it. This has led to several manufacturers including a backup “cat” in their aftermarket emissions equipment. Installing this part enables you to resume driving more quickly than changing your damaged original catalytic converter. This article will demonstrate how to perform catalytic converter replacement on a 2008 Honda CRV. Attention readers: The inspection or diagnosis of failed components is not covered in this blog post. The procedures described here are solely for people who are certified to handle the dangerous substances and chemicals found in most exhaust systems; if you have any questions about any of the information below, speak with a certified mechanic before continuing.
To Install a New Catalytic Converter on a Honda CRV 2008
Knowing what broke is the best way to know where to start because every vehicle is unique. There are a few essential things to check for while changing your catalytic converter that may reveal why it malfunctioned and where it is located in your CRV’s exhaust system. Check the O2 sensor first to make sure it hasn’t been harmed by the damaged converter. The O2 sensor regulates when the catalytic converter is in use; if it is broken, the replacement converter won’t function properly. Next, examine sure no plumbing has been harmed by a broken converter by inspecting the exhaust manifold. The location of the damaged converter is the final thing to search for.
Tools You Will Need
– Wrench set – Socket set – Prybar – Ratchet – Torque wrench – Jack and jack stands – Screwdrivers – Safety goggles – Gloves
Step 1: Drain The Existing Catalytic Converter Fluid
Before disconnecting anything, you should first drain the fluid that is currently in the catalytic converter. It is very likely that the fluid inside the converter will be contaminated if it has been damaged for a while, which could harm the replacement catalytic converter. You must uncouple the flexible coupling in order to drain the fluid into an appropriate container.
Step 2: Remove the Exhaust Manifold
The gaskets and several bolts that make up the exhaust manifold seal the exhaust system. It takes a pry bar to remove the manifold since it is made to allow the exhaust system to flex under pressure. Each exhaust manifold bolt can be loosened with a prybar before being entirely separated from the manifold and gasket. Place the manifold on a spotless, level surface after lifting it off the engine.
Step 3: Disconnect The Oxygen Sensor And Chain
Once the damaged converter has been taken out of the system, the exhaust chain is in charge of removing it. You must first unplug the oxygen sensor from the damaged converter before you can remove the chain from the exhaust manifold. Use a set of pliers to remove the sensor boot and a wrench to loosen the sensor in order to detach it from the damaged converter. Utilizing a wrench, remove the exhaust chain from the exhaust manifold.
Step 4: Remove The Broken Catalytic Converter
The broken catalytic converter can be manually removed from the exhaust line after the chain and oxygen sensor have been removed. Discard the damaged catalytic converter after removing the damaged converter.
Step 5: Install The New Catalytic Converter
The new catalytic converter may be installed now that everything has been taken out of the exhaust line. Apply a small amount of gasket sealant to the facing where the new converter will be installed before you install it. This will aid in sealing the connection between the new converter and the exhaust manifold and stop exhaust gases from escaping the system. You should reinstall the exhaust chain, sensor, and manifold in the opposite order that you removed them after the new converter has been placed.
