Automobile emissions are one of the leading sources of planet-wide pollution. Well-maintained cars can do enough damage to the environment. One in need of a new exhaust gas recirculation (EGR) valve is a downright menace to clean air.
An EGR valve runs exhaust fumes through your Dodge Dakota's combustion system again to burn off excess gas and cut back on emissions.
If a Dodge Dakota needs a smog check, it probably is due to an EGR valve in need of replacement. Most EGR valves are attached to the engine by 12 mm bolts. These bolts are removed easily for do-it-yourself replacement.
An alternative to do-it-yourself replacement is to buy the part from an auto parts shop and take it to the dealer, along with your Dakota, for replacement. A replacement EGR valve often is cheaper if bought from a third-party source, rather than a Dodge dealership.
