The nitrogen oxide that's trying to escape through the exhaust system has another job to do. The exhaust gas recirculation system returns some of the gas so it cools the combustion process, and uses it to lower the temperatures in the exhaust valves, too. If the EGR valve for Chevy Tahoe doesn't do its job, your SUV doesn't serve you as well, so don't delay the repair. Purchase new Chevy Tahoe replacement EGR valves from AutoAnything and enjoy our 1-Year, Lower Price Guarantee.
