2024 Chevy Duramax Diesel Exhaust Fluid Change. I ordered a 2024 denali and now i’m worried. Checking the def fluid level is an essential.

6.6l duramax l5p maintenance schedule and service information, including service part numbers, oil and fluid specifications, and fluid capacities. Some drivers assume they just need to fill up their def tank, but it may actually be the pump that needs replacing.
