What to know about the EGR Cooler:

The EGR (or Exhaust Gas Recirculation) Cooler cools exhaust gases after leaving the engine so the gas can go back into the engine without taking any excess heat into the mix. Running a small amount of exhaust gas back into the air intake enables the engine to have a more controlled combustion temperature in order to run more competently and produce less harmful exhaust.

Facts to Note:


Sometimes EGR coolers in working order prevent operating appropriately because of carbon buildup.

The EGR cooler is vital to keeping more sensitive engine parts at the right temperature.

One of your expert mechanics will be able to examine the entire intake and turbocharger parts while checking the EGR cooler, making sure that preventative upkeep can be done to guard the engine in the long-term.

How to Fix:


The hood is taken up and secured and coolant is drained

The EGR Cooler nuts and hose clamps are loosened and taken out

The EGR cooler is similarly taken out and gasket surfaces cleaned

The new EGR cooler is fixed with new gaskets and the nuts tightened

The coolant is refilled and the vehicle is road tested to make sure that there are no air leaks or drivability issues

Our Proposal:

Our expert mechanics recommend changing your EGR cooler every 80,000 miles. However, this number can differ with regards to your vehicle, so be sure to refer to your vehicle’s manual for the manufacturer’s advice. Let one of your expert mechanics examine the part if you observe anything strange. Monitor for excess temperature in the engine or other symptoms of a bad EGR cooler in higher-mileage engines. This part is a key part in controlling both the temperature of the engine and curbing the harm caused by the exhaust gases.

Common symptoms indicating you may need to change the EGR Cooler:

High engine temperature

Thicker or more noxious exhaust

Lowered engine efficiency


Cooling system working harder than usual

Importance of this service:

This service is extremely essential if the vehicle is already showing symptoms of a defective EGR cooler. The EGR cooler is in control of keeping the engine’s combustion from raising the temperature too high. If the engine gets too hot, parts may either break or become weakened by the excess heat. If this is not checked, the exhaust fumes may be too harmful to pass a state-required inspection or smog test.
