GMC Sierra EGR Valves & Parts

The GMC Sierra is a luxury-oriented full-size pickup which was released by the automaker back in 1988 and has been marketed in North America up to present. So far, the vehicle has been available in three consecutive generations, and throughout its history, it has undergone significant changes to remain attractive to its target audience. The third generation of the Sierra appeared in dealerships in 2014 and featured the all-new GMT K2XX platform. The majority of versions of this full-size pickup gained a new EcoTec engine, with the available displacements of 4.3 L, 5.3 L and 6.2 L. The only Vortec engine option which was brought to the lineup from the second gen is a 6.0 L V8.

If modern vehicles didn't have emission control parts, they would significantly pollute the environment. The most dangerous substance which is produced during the operation of an internal combustion engine is hydrocarbon, which leads to smog formation. It may be burnt at certain temperature, that is why vehicles have got an EGR valve which returns certain exhaust fumes back to the engine, so that they could be eliminated. If the EGR valve on your truck doesn't function properly, you might need to replace it so your vehicle can pass the emissions test.
