Can EGR cooler be cleaned?
That’s a reasonable idea; EGR coolers are like radiators, only they use water to cool hot exhaust gases, instead of air to lower the hot water’s temperature. That means they can be cleaned like a radiator. If the water runs clear, that’s as good a job your liquid cleaner is going to do.
How often should you clean EGR cooler?
When it comes down to it, you should probably clean your cooler when it gets dirty, whether that means flushing it out every 10,000 miles or 80,000 miles. Cleaning intervals determined by frequent inspection may reduce the chance of failure due to carbon build-up.
What does it mean to delete the EGR cooler?
An EGR delete is the device that can be used to block off and delete the EGR cooler or at least the functionality of the EGR system. Most EGR deletes stop or block the flow of exhaust gases from flowing through the EGR cooler. Therefore, it prevent the EGR system from functioning properly.
Can a bad EGR cooler cause an engine to overheat?
If the EGR cooler has any issues that restrict the flow of exhaust gases through the cooler it can cause the engine to overheat. Over time, carbon can build up on the inside of the EGR cooler and restrict flow through the cooler.
What does EGR stand for in diesel engine?
The term “EGR Cooler” has and will continue to become more popular in diesel repair shops in the United States and around the world. Many of you may be asking why this is or what does an EGR Cooler do. Let’s answer a few questions: What does “EGR” stand for? Exhaust Gas Recirculation. Why do most of the latest diesel engines have EGR Coolers?
Can a check engine light come on with an EGR delete?
While it has been possible in the past to use tuners to prevent the check engine light from coming on when an EGR delete is installed, there is no guarantee that this functionality will be available in the future.
What does EGR cooler cleaning on Ram do?
EGR cooler removal, inspection and cleaning on Ram 2500 – 3500 6.7 Cummins diesel. Part of preventative diesel maintenance at around 75k. And for US consumers, where diesel fuel quality is pretty bad, this cetane booster might help you with lot’s of headaches!
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.
What do you need to know about the EGR delete?
An EGR delete is the device that can be used to block off and delete the EGR cooler or at least the functionality of the EGR system. Most EGR deletes stop or block the flow of exhaust gases from flowing through the EGR cooler.
When to do EGR maintenance on a Cummins diesel?
Ironically enough, most EGR-related issues surface after the 70,000-mile mark in most Ram pickups, so if this maintenance is performed at the appropriate time, much of the 6.7L Cummins’ EGR issues can be avoided. While EGR valve issues are much more common, EGR cooler failures do happen on 6.7L Cummins mills.
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.
