Cummins 6.7L owners are aware that there is a service required at the 67,500 mile interval: change the crankcase vent filter, clean the exhaust gas recirculation (EGR) valve, and EGR cooler assembly.
If you price these parts over-the-counter at Mopar the cost is $180 plus $40 for the cleaning solution.
We would suggest using the Cummins equivalent parts for the gaskets and filter that are needed and we'd also suggest using Simple Green (it smells just like the Mopar cleaner) as your cleaning solution.
This Geno's Garage 6.7L EGR Cleaning Kit contains the following:
- (2) EGR valve gaskets
- (1) Small exhaust manifold gasket
- (1) Large exhaust manifold gasket
- (1) EGR butterfly gasket
- (3) EGR plumbing gaskets
- (1) Airhorn gasket
- (2) rubber plugs
Freddie Frugal knows that if you are going to spend time cleaning the EGR valve and EGR cooler, that you'll remove and clean the intake air horn that the EGR valve is bolted to. The replacement gasket for air horn-to-intake manifold is 4940849 and it is included in our EGR Cleaning Kit.
Additionally, our kit has thorough instructions for removal of the parts and tips on best method(s) for cleaning.
Finally, Freddie Frugal adds two rubber plugs for the ends of the EGR cooler assembly so you don't waste cleaning fluid. Fill up the cooler, cap it off, and soak it overnight. Use the caps to shake the cooler with the cleaner inside.
