Install Catalytic Converter Without Welding
Posted By admin On 20.09.19Welcome to our. Ever wondered how do vehicles minimize the pollution from their emissions?Well, a device called catalytic converter converts the pollutants into eco-friendly or harmless gases. The major vehicular pollutants are carbon monoxide, hydrocarbons, and heat generated gases (nitrogen oxides).A catalytic converter uses a catalyst in the form of platinum or palladium which converts these harmful gases into harmless gases.Over a period, the catalytic converter loses its functionality and needs replacement. Therefore, let us know how to replace and install a catalytic converter for your vehicle. What is a Catalytic Converter?A catalytic converter is a mechanical device inserted in the emission system of vehicles that use. It forms a series of reduction and oxidation (redox reaction) reactions which reduce the hazardous emissions from the vehicles.French mechanical engineer Eugene Houdry was the pioneer in commercializing the catalytic converter.
I need a new cat for my 1996 GMC van. As a beginner amateur welder I was hoping to weld it in myself but decided not to for various reasons. Anyway my local muffler shop quoted me $175 for labor to weld this in. Is that about right? The job seems relatively straightforward. It would involve cutting out the existing cat and welding the new one in. 3 inch pipes. I took it to an auto exhaust shop that is well known (according to reviews) in the area for their skilled welding work. They lowered the exhaust and sealed up the cat's crack with no issues for $170. In fact, they knew it was the catalytic converter before I even told them. Apparently, it is common issue on the Mercedes W211 E-Class cats. The total cost of a catalytic converter repair is $950 - $2500, with labor costs at $70. From the factory, it's welded into the exhaust pipe while many replacements. In some cases, the core inside the catalytic converter can start rattling without. You'll have to get a new catalytic converter installed to pass your next smog test.
He studied the effect of smog (smoke + fog) on the environment and was concerned about the impact of vehicular pollution on the environment. The Catalytic Converter Has The Following Components. The nitrogenous emissions are reduced (removal of oxygen) to nitrogen and oxygen. Nitric oxide (NO) and Nitrogen dioxide (NO2) are the major nitrogen compounds from fuel combustion which cause acid rains and smog.On the other hand, an oxidative reaction will add oxygen to carbon monoxide (CO) and turn it into carbon dioxide (CO2). It also turns hydrocarbons into water (H2O) and Carbon dioxide.In total, three reactions are happening in a catalytic converter, and hence it is called as three-way conversion and so the converter as a three-way catalytic converter.Catalytic converters used in gasoline vehicles are three-way catalytic converters whereas those used in diesel vehicles are two-way converters. Conversion of hydrocarbons is omitted in diesel engines because they do not emit much heat as gasoline engines do.
When to Replace a Catalytic Converter?In general, catalytic converters have a very long lifespan. They can last up to 10 years. But there are sure signs which indicate that you have to replace them. These signs are.
Steps In Removing The Catalytic ConverterThe first step is to raise your vehicle so that you can move freely beneath the vehicle. Raise the vehicle to your comfort level and secure it with jack stands.Do not forget to engage the. If you are using a manual vehicle (geared), you can further secure the movement by putting the vehicle in gear.Locate the Converter: Once the vehicle is raised, locate the catalytic converter. It is usually placed just before. Some vehicles may have multiple converters, and you have to locate the converter which you are intended to replace.Remove the Sensor: After finding the converter, remove the oxygen sensor from it.
Some oxygen sensors are mounted over the converter while some are inside it. Use the appropriate wrench or ratchet to remove the sensor. If there is no oxygen sensor, you can proceed to the next step.Remove the Converter: Now, it is time to remove the catalytic converter itself. Most converters are bolted to the exhaust. These bolts will usually get rusted over time. To remove the rusted bolts, use a penetrating oil.Spray/pour over the bolts and let them soak for few minutes.The penetrating oil will make it easy to remove the rusted bolts by penetrating between the threads of the bolt (lubricating action).
After lubricating the bolts, use assorted wrenches suitable for the bolt size and remove them carefully.You may require extension joints or shoulders depending upon the location of the converter and the bolts on it.For welded converters, use the Sawzall or any other similar to cut off the converter from the exhaust manifold. Steps For Removing A Built-In Catalytic ConverterCertain vehicles have catalytic converters which are installed directly to the engine (cylinder heads). Locate the converter under the hood which is built into the engine.The built-in catalytic converters are usually bolted (not welded) to the cylinder heads.Locate the bolts and use penetrating oil if necessary. Use suitable assorted wrenches and remove the catalytic converter.

Steps For Installing The Catalytic ConverterAfter you have successfully removed the old catalytic converter, just follow the steps of removal in reverse mode. Re-check all the steps you have and make sure they are perfect. Frequently Asked Questions (FAQs) About Catalytic Converter 1. How often should I replace the catalytic converter?A catalytic converter will last long, and it does not require frequent replacements. If you are in doubt, take professional help.

What are the general precautions to be taken while replacing a catalytic converter?Make sure your vehicle is secured over the jack stands. Always wear protective gear such as gloves, eye, and ear protection while doing the job. If you are unsure about the procedure, seek technical help. Is it okay to replace one catalytic converter if the vehicle has multiple converters?It is fine to replace one (damaged or non-functional) catalytic converter if your vehicle has multiple units. Bolt's won't turn, what should I do?Spray the penetrating oil and leave it for at least five minutes. It will lubricate them, and you will easily remove them.ConclusionThe procedure of replacing and installing a catalytic converter varies from vehicle to vehicle. This guide is a general guide, and it is always good to follow the instruction manual.The overall procedure is the same for all vehicles except for the type and location of the converter and the presence of the oxygen sensor.If you are unsure about the procedure, get it done by a professional.
