An EGR (Exhaust Gas Recirculation) cooler is a component commonly found in modern internal combustion engines, especially in diesel engines. Its primary function is to cool the recirculated exhaust gases before reintroducing them into the engine’s intake system. Overall, the EGR cooler plays a crucial role in modern engine emissions control systems by ensuring that recirculated exhaust gases are at an appropriate temperature before being reintroduced into the engine’s intake system.

As a rough estimate, the cost of replacing an EGR valve typically ranges from $500 to $1500 or even more, including parts and labor. However, it’s essential to get a specific quote from a mechanic or auto repair shop based on your vehicle’s make and model, as well as the local market conditions. Additionally, if your vehicle is still under warranty, the replacement cost may be covered depending on the warranty terms.
