Consumables 4.3 Coolant Cooling system corrosion protection agent The inspection of the concentration of cooling system protection agent can be carried out with standard testing devices (e.g. refractome- ters). 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. 4 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.
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. 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.
