Febi has highlighted the important role that EGR coolers play in managing vehicle emissions and issued some useful advice on how to spot when these components may be faulty.

The Exhaust Gas Recirculation (EGR) cooler helps to ensure vehicles meet the Euro 6 emission standard by using engine coolant to reduce exhaust temperatures, helping to prevent the formation of oxides and pollutants such as nitrogen oxide (NOx).  Once the combustion temperatures have been cooled, the gas is recirculated through the engine’s intake system.  This helps to reduce pollutants and thermal stress on cylinder head gaskets and exhaust valves, helping to extend component life.

Not all vehicles have EGR coolers, but for those that do, it is a vital component to ensure driving performance is maintained. Over time, carbon can build up in the EGR cooler which causes a restriction of the coolant flow. It is important to replace EGR coolers if fitted to the vehicle as recommended by the manufacturer.

Symptoms of a worn, clogged or faulty EGR cooler include:

• Engine overheating. If coolant flow is restricted, the EGR cooler is unable to cool the exhaust gases. This not only allows NOx emissions to continue, it also causes overheating which can cause serious damage.
• Loss of coolant from the cooling system. This could be causing an internal leak in the exhaust system that could result in poor engine performance, and even cause more costly repairs.
• Check Engine Light flashes on the dashboard. Restricted flow, or a problem with the exhaust function can activate the Check Engine Light. However, as a wide variety of other issues would flag the same warning light, it is important carry out a thorough diagnostic check.
