The 2003 Dodge Durango indeed comes with an EGR valve, as confirmed by the manufacturer. This valve is located on the rear left cylinder head and is linked to the intake manifold. The EGR valve plays a crucial role in reducing Nitrous emissions in engines by recirculating exhaust gases. This process lowers the oxygen levels inside the combustion chamber. If needed, the EGR valve can be taken out and cleaned instead of being replaced, as they often just require maintenance. Replacing the EGR valve will cost around $30 to $60, depending on whether you opt for an OEM or aftermarket component.
Certainly. Instead of needing to be swapped out, they can frequently be simply cleaned.
