🚛 Attention Cummins 6.7 Owners & Fleet Operators! 🚛
Prevent costly downtime and extend your engine’s life with a professional EGR valve and EGR cooler cleaning service.
🔧 Why It Matters
The EGR system recirculates exhaust gases back into the intake to reduce emissions — but over time, soot and carbon build up inside the EGR valve and cooler, restricting flow and leading to:
• Rough idle or reduced performance
• Check engine lights or EGR-related codes
• Overheating and potential cooler failure
📅 Recommended Service Intervals
EGR cleaning intervals can vary slightly depending on the model year and duty cycle:
• 2007.5–2018 6.7L Cummins: every 67,500 miles (recommended)
• 2019+ models: inspect/clean around 75,000 miles, or sooner if heavy idling or city driving
• Always follow the Cummins or manufacturer maintenance schedule for best results
⚠️ What Causes Excessive Carbon Buildup
Certain driving conditions can cause accelerated soot accumulation, including:
• 🚛 Short trip driving where the engine doesn’t reach full operating temperature
• ⏱️ Excessive idling — common with work trucks and fire apparatus
• 🏙️ Stop-and-go city driving
• 🧊 Cold weather operations with extended warm-up times
• 🧰 Low-quality fuel or poor maintenance (dirty air filters, old oil, etc.)
