The amount of time needed to replace the catalytic converter must be factored in as well, which varies for every car. Labor costs to replace a catalytic converter can range anywhere between $70 and $130 an hour. Labor Cost to Replace a Catalytic Converter Expensive units have high catalyst density, often up to 6 times as compared to the budget versions. Cheaper units generally have a much lower density of these particles, so they are less efficient and fail quickly. As stated, they are made of catalyst metals like palladium, platinum, etc. There is also a big difference in the internal design of a converter. There are universal fit units that cost less than $100, and direct fit, purpose-built converters can cost $1000 or more. Remember not all catalytic converters are created the same. Depending upon the model, the cost of the unit could be a few hundred bucks up to a couple thousand to replace a catalytic converter! Quality of Replacement Unit If your car model dates back to the nineties, then the catalytic converter replacement is going to be much less than compared to a car bought in the 2000s. To determine the average cost to replace a catalytic converter, sever factors must be considered, such as: Vehicle make and model How Much Does It Cost to Replace a Catalytic Converter? Antifreeze has leaked into the exhaust.Oil or unburned fuel has seeped into the exhaust.The oxygen sensor isn’t functioning properly.Moreover, no one keeps a car for 15 years anymore! These are the general reasons for catalytic converter failure: But the components of a vehicle are all interlinked, so if one fails to operate properly, the effects cascade onto the rest. It is for this reason that they are usually designed to last for at least 10 to 15 years, which is the lifespan of a car. The common logic is that catalytic converters don’t have moving parts, so they ought to last forever. What are the reasons for the failure of a catalytic converter? It must work harder to generate the same power, which means using up more fuel. If your catalytic converter is blocked up, then your engine won’t be getting the airflow it needs to function properly. The lesser the airflow, the lesser the power, which means poor acceleration! Fuel Economy Issues When the converter is blocked, it generates an improper amount of backpressure in the exhaust system, which compromises airflow. Internal combustion engines depend on airflow to operate. It leads to partial blockage in the converter, which adversely effects vehicle performance. The Car’s Acceleration Is PoorĪn excess of carbon buildup in the honeycomb design of the catalytic converter can eventually lead to failure. Typically, this is converted into sulfur dioxide that is totally devoid of any smell, but when the catalytic converter isn’t working the way it should, the hydrogen sulfide comes out of the exhaust pipe with a horrible smell. The unpleasant odor of rotten eggs is often due to a compound called hydrogen sulfide. That is why the engine check light goes on. Take your car in for a diagnostics test, so you can know for sure if the cause for this phenomenon is a poor catalytic converter. If the catalytic converter is malfunctioning, the oxygen sensor in the exhaust stream could be sending a signal to the engine control unit to indicate something is wrong. If the catalytic convertor isn’t functioning properly, then your car is likely to be released more exhaust gases than it should. Several states have made emissions testing compulsory. How to Spot the Signs of a Faulty Catalytic Converter The Car Failed Its Emissions Test When the vehicle operates, exhaust gases flow through the catalytic converter and three harmful compounds – hydrocarbons, nitrogen oxides, and carbon monoxide – are superheated, and react with the catalyst that converts them into emissions that are less harmful. The inside of the catalytic converter houses a ceramic honeycomb component that is coated in catalyst particles of platinum, palladium, and rhodium. There aren’t any moving parts or elaborate computer tech involved. The design of catalytic converters is fairly simple.
