frequently asked questions (faqs)
Q. will Def containers have a date stamp?
a.
Yes, each container should be dated.
Q. how do you monitor a truck’s Def level?
a.
Very easily. A DIC message will alert the driver whenever a vehicle’s DEF
level begins to run low (see DEF levels explanation earlier in this brochure).
Q. is there a Def level gauge?
a.
No. Since the DIC displays DEF level messages, there’s no need for a
dedicated DEF level gauge.
Q. is there ever a situation where the truck will not start or drive due to
lack of Def?
a.
No. You’ll never run into a situation where the truck will not start and
drive. However, your speed may be limited (see DEF levels portion of
this brochure).
Q. can you mix fresh Def with older Def?
a.
Yes, since adding new DEF does not change the mixture ratio you can mix
the two together.
Q. what will happen if some other type of liquid is poured into the
Def system?
a.
DEF is the only fluid approved and recommended by General Motors. Using
a product not recommended by GM will trigger a DIC warning message and
may damage the SCR system and void the warranty coverage (see DEF
quality portion of this brochure).
Q. is there a drain plug on the Def tank?
a.
No, there is no drain plug on the DEF tank. However, the tank is designed
to be easily removed.
