Research on Catalytic Converter for GMC Sierra 1500

The power of a pickup truck demands there is an efficient exhaust system. The catalytic converter is central to having clean exhaust, and a truck that supplies a minimal level of pollutants to the atmosphere. Your vehicle's cat is under constant stress. It is in direct line of the hot exhaust stream, so over time it can wear out. This can cause many performance issues. Fortunately, it's not hard to find replacements, and you can even find significant savings where once it was a challenge to.

What Is the Catalytic Converter?

Providing emissions control in your truck, the catalytic converter is able to convert toxic gases such as carbon monoxide into carbon dioxide and water. It is able to catalyze an oxidation and reduction reaction. First developed to reduce emissions from smokestacks, it was perfected for automobiles in the 1950s. The catalytic converter, or cat, features a ceramic monolith that supports catalysts such as platinum, palladium, rhodium, or other precious metals. There are also oxides for oxygen storage, and a washcoat to disperse the catalytic materials across a large area. A deficiency in any of these components will warrant GMC Sierra catalytic converter removal.

Where Is the Catalytic Converter Located?

The 2000 GMC Sierra catalytic converter, for example, is located on the underside of the truck, near the exhaust manifold. There are in fact two cats in the GMC Sierra. They are place to maximize the exposure to hot exhaust gases. In order for harmful gases to be converted into an inert form, a temperature of at least 800°F is required. Integrated catalytic converters now maximize efficiency and save space.

Recognizing Signs of a Catalytic Converter Problem

Symptoms of your 2003 GMC Sierra catalytic converter failing include a drop in fuel efficiency. The most obvious sign is if the truck fails an emissions test, or the Check Engine light comes on. If the engine misfires, the cat can overheat, or if it is clogged then exhaust gases won't be able to pass through the exhaust system. Back pressure can reduce the performance of the engine, creating lapses in acceleration and making the truck feel jerky. Testing a failing catalytic converter can uncover the presence of fuel vapor, a sure sign of a clog.

What You Can Expect to Spend Replacing a Catalytic Converter

In a 1999 GMC Sierra 1500, replacement costs range from $596 to $1,061 for a front catalytic converter. A 2004 GMC Sierra catalytic converter is a few dollars extra, ranging anywhere from $605 to $1,072. The rear cat of a 1999 and 2004 model can cost as high as $1,141. Compared to past models including the 1999 GMC Sierra catalytic converter, replacement for a recent 2015 model truck is in a similar range but slightly higher, going from $726 to $1,136. Expect labor to increase the final price, although parts will account for most of this. Even with catalytic converters, savings are possible by going with online suppliers such as PartsGeek.com. Our pricing model stems from the fact we sell exclusively online, limiting overhead and enabling us to pass on the savings to you, so maintaining your ride is less of a hassle.
