Replace the failed EGR Coolers & Components in your 2017-2022 Ford 6.7L Powerstroke. Common signs that your EGR Cooler could be failing are white smoke, low coolant levels, a sticky EGR valve, or possibly a check engine light. Since the EGR cooler connects the exhaust and cooling systems of your engine, failures inside the cooler can lead to coolant loss, overheating, and possibly engine damage. The main function of an EGR cooler is to lower the exhaust gas temperature before it is recirculated back into the engine. On many diesel engines EGR coolers can be prone to blockages or leaks over time. One of the initial signs of failure can be white smoke exiting the tailpipe. This is steam from boiling water or coolant. If the EGR cooler has cracked or failed, the coolant passages can begin to leak. The coolant will start to mix with the exhaust and will enter the intake. Next, it is heated by the exhaust or inside the combustion chamber and is then pushed out the tailpipe. Besides white smoke, you may also start noticing a reduction of coolant in your overflow bottle or degas tank. If you have to occasionally fill your coolant system, and you don't notice any drips or spots on the ground, the coolant may be exiting through the exhaust. Another item to check is the EGR valve. It will typically be covered in carbon buildup and be a dark black color. When coolant enters the EGR system, it can mix with this carbon. Small amounts of coolant can mix with this carbon and will create a sticky buildup. In some cases, there may be enough coolant passing through to strip away all of the carbon. This can result in the valve looking like it has been cleaned. Factory OE-style replacements and upgraded EGR cooler designs are offered for a variety of Duramax, Cummins, and Powerstroke engines.
