Exhaust Recirculation Valve Upgrade

Exhaust Gas Recirculation Valve

Before I start, let me say the Exhaust Gas Recirculation valve is an emissions related device that may be required to pass SMOG in the near future. That being said, EGR systems are what cause the 6.0 to overhead and puke coolant out of the reservoir. The EGR diverts 1000+ degree exhaust gas and attempts to cool it using diverted engine coolant.

Simple math and common sense dictate this is a terrible idea, and the coolant flash boiling is the obvious outcome. When the coolant boils, it becomes vapor. Rapidly expanding vapor takes up more space than liquid, which pressurizes the cooling system. The system is entirely sealed, leaving nowhere for the coolant to go but steaming out of the reservoir cap. Not only is it embarrassing to be pulled over with your hood up in a new truck spewing steam, but overheating the engine can cause serious long term damage.

Deleting the EGR is fairly straightforward, and takes about 5 hours to do. Once installed, the difference is night and day. Average coolant operating temperatures drop by 40 degrees and the performance gains are estimated about 10 horsepower due to the removal of the exhaust restriction. Trust me on this one; it’s one of the best things you can do for the 6.0

  1. Greg, I have the same issue on my 05 Harley f-250 and was wondering who did the work for you in Charlotte or whether you could recommend a shop that could.

  2. We have the parts in stock and can transfer them into the Charlotte store at no extra charge! Feel free to call me for the details at 800-337-9005 ext 5106.

  3. Well, thanks to the good ol’ government, we can no longer sell any items the ‘tamper with emissions’. Even though this product makes the truck run better and cleaner, it’s one of those stupid technicalities. Just because I don’t sell it doesn’t mean you don’t need it! Delete your EGR today (for off roading purposes only, of course).
