Maintenance Specications
Diesel Exhaust
Fluid (DEF)
During normal operation of the truck,
the DEF tank straps may relax. Inspect
the spring on top of the strap. If more
than ½” (12.7mm) of the spring is
exposed (1), the bolt will need to be
re-torqued between 70 - 80 in-lbs. (7.9
- 9 Nm). This distance is measured
from the washer at the end of the
spring to the edge of the tube at the
top of the straps.
