What does it mean when an EGR cooler fails?

An EGR cooler primarily fails by cracking internally. There are no moving parts in an EGR Cooler. An EGR cooler is simply a heat exchanger which exchanges heat from the exhaust air to the engine coolant.

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.

Can a GDE tune block the EGR cooler?

If the GDE Tune closes the EGR Valve “permanently”, and the coolant is blocked from entering the cooler, then I would believe this should suffice. turned off with the tune , but members have had the fail even thousands of miles after installing the hot tune .

What happens if the gaskets on the EGR cooler fail?

If the EGR cooler gaskets fail, or the cooler gets damaged for any reason, it can cause an exhaust leak to develop. An exhaust leak may be heard as an audible hissing or tapping sound coming from the front of the vehicle. This will reduce the efficiency of the EGR system, and negatively affect engine performance. 3. Check Engine Light comes on

Is there a way to 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.

What are the moving parts in an EGR cooler?

There are no moving parts in an EGR Cooler. An EGR cooler is simply a heat exchanger which exchanges heat from the exhaust air to the engine coolant. One portion of the EGR cooler has exhaust gases flowing through it (latest designs use tubes) while the other portion of the EGR cooler is flooded with engine coolant.

How much does a 6.7L EGR cooler cost?

Another benefit of the design improvement in the 6.7L is the replacement and maintenance cost. There are two EGR coolers on a 6.4L; the lower is about $500, the upper is about $400. Usually you have to replace both of them with a tremendous amount of labor involved.

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?

What happens when an EGR cooler goes bad?

After many cycles of heating up and cooling down, the thermal expansion/contraction causes the materials inside the EGR cooler to fatigue and fracture. When this happens, engine coolant mixes with the exhaust stream. How do you diagnose a failed EGR Cooler? There are a few things you can check to determine whether or not your EGR cooler has failed:

When did Ford replace the EGR cooler in my van?

Dealer records show that my 100K van has had EGR cooler replaced twice already, once around 20K when it failed and once at 80K with a Ford recall (17E07). Most recently in response to a P24A5 code the dealer diagnosed it as a broken EGR valve and replaced it under warranty.

What causes a Cummins ISL EGR cooler to fail?

The root cause for the EGR cooler failure (in most instances) is mostly caused by the engine oil cooler partially clogging up inside and the coolant in the EGR cooler gets too hot due to low circulation, it will begin to deteriorate the solder joints in the EGR cooler as the over heated antifreeze…
