What is the purpose of the catalytic converter and how can you diagnose and repair a malfunctioning one on Ford Expedition?

A catalytic converter reduces pollutants in exhaust gas using a single-bed design and a three-way catalyst coated with platinum and rhodium. This reduces levels of nitrogen oxides, hydrocarbons, and carbon monoxide. If you suspect a malfunction, take your vehicle to a dealer or authorized facility for diagnosis and repair. Check the converter for leaks or damage when the vehicle is raised for servicing. If damaged, it should be replaced, requiring removal of the exhaust pipe assembly. This can be done at a dealer service department or muffler shop.

Ford Expedition Catalytic Converter

The Catalytic Converter in Ford Expedition cars is part of the exhaust system, where the dangerous gases such as CO, HC, Nox, etc are changed into less dangerous gases such as water, CO2 and Nitrogen. This device has components such as platinum, palladium and rhodium which act as catalysts; the components change the rate of specific chemical reactions but are not themselves changed in the process. The Catalytic Converters used over the years have changed and while some have the honeycomb like structure the others have the ceramic beads. However, these converters can suffer from catalyst poisoning and theft due to constitutional of precious metal, but the progress has been made for eliminating the exhaust restriction and boosting the performance. Ford Expedition comes with both the factory fitted converters as well as after-market universal converters, factory fitted converters being easier to slot and having the premier oxidation and reduction capacities for the engine as opposed to the universal units.

We provide a wide range of Ford Expedition Catalytic Converter at the best prices possible. If you need Ford Expedition Catalytic Converter, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
