The EGR (or Exhaust Gas Recirculation) Cooler cools exhaust gases after they exit the engine so the gas can go back into the engine without carrying any excess heat into the mix. Running a small amount of exhaust gas back into the air intake allows the engine to have a more controlled combustion temperature in order to run more efficiently and produce less harmful exhaust.
Our expert mechanics recommend replacing your EGR cooler every 80,000 miles. However, this number can vary depending on your vehicle, so be sure to refer to your vehicle’s manual for the manufacturer’s advice. Have one of our expert mechanics inspect the part if you sense anything unusual. Keep an eye out for excess temperature in the engine or other symptoms of a bad EGR cooler in higher-mileage engines. This part is a key component in controlling both the temperature of the engine and curbing the harm caused by the exhaust gases.
This service is extremely important if the vehicle is already showing symptoms of a faulty EGR cooler. The EGR cooler is responsible for keeping the engine’s combustion from raising the temperature too high. If the engine gets too hot, components may either break or become weakened by the excess heat. If this is not checked, the exhaust fumes may be too noxious to pass a state-required inspection or smog test.
