What are the signs of a bad EGR cooler?
Here are three indicators of a bad EGR Cooler: White Smoke – while that pesky Valve can cause an abundance of black smoke billowing from the pipes, a failing EGR Cooler actually emits white smoke, or steam, caused by evaporating coolant inside the cooler. When you see white smoke, call for help.
Can I bypass the EGR cooler?
You can sandwich a plate at the intake and exit of the EGR Cooler. No need to block of the EGR Tube as you will have a tune that effectively shuts off that path to the intake. This way no exhaust gases and no coolant will pass through the EGR Cooler. If/when I am ready to bypass the EGR cooler, that is what I will do.
Does EGR delete remove 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.
What does a EGR bypass valve do?
EGR bypass valve – Located on the intake inlet. The ECM uses this valve to allow exhaust gas into the engine without going through the EGR cooler (EGR cooler bypass).
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.
Can you replace the EGR cooler on a 2007 Truck?
Another driver told of a bad experience trying to bypass emissions controls on his 2007 engine, and had to replace the whole system eventually, so he obviously didn’t recommend it. But frustration around EPA-compliant engines post-2007 is understandable. Replacement parts are very expensive: a blown EGR cooler can cost thousands of dollars.
How much does a blown EGR cooler cost?
But frustration around EPA-compliant engines post-2007 is understandable. Replacement parts are very expensive: a blown EGR cooler can cost thousands of dollars. Perhaps part of the problem lies with the OEMs, themselves, and poor communications after some start-up problems with the first generation EGRs.
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.
