Cooling system corrosion protection
agent
The conditioning of the coolant for liquid-
cooled DEUTZ compact engines is done by mi-
xing an antifreeze with corrosion protection in-
hibitors on an ethylene-glycol base with the
water.
This cooling system protection agent is free
from nitrites, amines and phosphates and ad-
apted to the materials in our engines. Order
from your DEUTZ partner.
If the DEUTZ cooling system protection agent
is not available, please contact your DEUTZ
partner.
The cooling system must be monitored regu-
larly. This includes checking the concentration
of the cooling system protection agent, as well
as inspecting the coolant level.
When mixing coolant system corrosion
protection agents on a nitrite basis with
amine-based media, health hazardous
nitrosamines are formed!
Coolant system corrosion protection
agents must be disposed of in an envi-
ronmentally friendly way.

The inspection of the concentration of cooling
system protection agent can be carried out
with standard testing devices (e.g. refractome-
ters).
For temperatures below -35 °C, please have a
word with your responsible DEUTZ partner.
The use of other cooling system protection
agents (e.g. chemical corrosion protection
agents) is possible in exceptional cases. Con-
sult your DEUTZ partner.
