Signs your def tank has failed
- DEF heater codes (P20B9, P20BA and similar) in cold weather, with a derate
- DEF level reads empty, or stays full after filling
- Reductant quality codes with fresh, clean DEF
- Crystallized DEF around the tank cap, fittings or the bottom of the tank
- Leaks at the tank, sending unit or pickup
- Derate that appears only in freezing temperatures
Before you order
- Send your VIN — tank capacity, sensor package and mounting vary by chassis, wheelbase and year.
- Clean and flush DEF lines and the pump filter when the tank is replaced; crystals in the lines re-contaminate the new tank.
- Check the heater relay/fuse and connector before condemning the tank heater.
- Fill only with fresh ISO 22241 DEF from a sealed container after installation.

Frequently asked questions
Do you sell used DEF Tank for all medium-duty truck brands?
Yes — we carry used def tank units for Isuzu, Ford, Chevrolet, GMC, Ram, and Mitsubishi Fuso medium-duty trucks, not just the Chevrolet Silverado 5500HD.
Is this used DEF Tank tested before it ships?
Yes. Every def tank we sell is inspected and tested before it ships, so it works right the first time.

Do you offer a warranty on this DEF Tank?

Do you ship this DEF Tank nationwide?
Yes — we ship to all 48 contiguous states with tracked delivery. Most parts arrive in 3–7 business days; engines, transmissions and axles ship freight and typically arrive in 5–10.
Does the tank include the heater and sensors?
Yes, as an assembly from the donor truck: heater, level sender and (where fitted) quality sensor and pickup.
Why does my truck only derate in winter?
The tank heater has failed. DEF freezes around 12°F; when the heater can’t thaw it the system derates until it can dose. A working tank heater ends the winter derates.
