Checking the DEF Levels. The storage tank is usually found either next to the diesel fuel tank on a truck, or near the area of the spare tire on a car. All vehicles with diesel engines meeting 2010 or later EPA guidelines have a dashboard warning system that alerts you when the DEF level is low.
Can you over fill your DEF tank?
The neck of the tank acts as a breather tube for DEF. If it is “capped off” by overfilling, the DEF within the tube crystalizes. Crystalized DEF prevents air from entering the tank. This means the pump can’t move the fluid out of the tank and do its job of breaking down the NOx.
