Can blocked EGR cause overheating?
Can blocked EGR cause overheating?
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.
What are the symptoms of a bad or failing EGR cooler?
Check Engine Light comes on Another symptom of a bad or failing EGR cooler is a Check Engine Light. If the computer detects a problem with the EGR system, such as insufficient flow or exhaust, it will set off the Check Engine Light to alert the driver of the issue.
How does an EGR air conditioner cooler work?
They function in much the same way as a radiator functions, by using the cool air passing through the fins to cool the exhaust gases as they flow through the cooler. When the EGR cooler has any issues, it can cause problems with the functionality of the EGR system.
Why is the EGR system in my car so hot?
The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines.
Is there a problem with the EGR valve?
EGR Valve Failed / EGR Cooler Failed – Dealer changed twice – Replace EGR Cooler with BulletProof Diesels upgraded cooler design, along with oil cooler (related problem) and oil screen below cooler. Problem has not resurfaced now at 150,000 miles. Their website is very helpful as is their part.
Check Engine Light comes on Another symptom of a bad or failing EGR cooler is a Check Engine Light. If the computer detects a problem with the EGR system, such as insufficient flow or exhaust, it will set off the Check Engine Light to alert the driver of the issue.
How is an EGR cooler used in an engine?
The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system. The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. An EGR cooler is a metal device that employs thin passages and fins to cool the exhaust gases.
The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines.
