What is the EGR Cooler all about?
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.
Keep in mind:
- Sometimes EGR coolers in working order stop operating correctly due to carbon buildup.
- The EGR cooler is crucial to keeping more sensitive engine components at the right temperature.
- One of our expert mechanics will be able to inspect all of the intake and turbocharger components while inspecting the EGR cooler, ensuring that preventative maintenance can be done to protect the engine in the long-term.
How it's done:
- The hood is raised and secured and coolant is drained
- The EGR Cooler bolts and hose clamps are loosened and removed
- The EGR cooler is removed and gasket surfaces cleaned
- The new EGR cooler is installed with new gaskets and the bolts tightened
- The coolant is refilled and the vehicle is road tested to ensure there are no air leaks or drivability issues
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.
What common symptoms indicate you may need to replace the EGR Cooler?
- High engine temperature
- Thicker or more noxious exhaust
- Lowered engine efficiency
- Cooling system working harder than usual
How important is this service?
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.
