Tank Straps
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, the bolt
will need to be re-torqued between 70 – 80
in-lbs. (7.9 – 9 Nm). This distance (1) is
measured from the washer at the end of
the spring to the edge of the tube at the top
of the straps.
