Please contact your DEUTZ partner if the DEUTZ cooling system corrosion protection agent is not available. en \SERVICE\Oils, Lubricants, Diagnosis\ Cool- ing System Conditioner The cooling system must be monitored regularly. This also includes checking the coolant system cor- rosion protection agent concentration in addition to checking the coolant level. The cooling system corrosion protection agent con- centration can be checked with conventional test in- struments (e.g. refractometer). Water percent- age Cold pro- tection up to min. 35 % 65 % -22 °C 40 % 60 % -28 °C max.
45 % 55 % -35 °C At temperatures below -35 °C, please contact your responsible DEUTZ partner. It is possible to use other cooling system corrosion protection agents (e.g. chemical corrosion protection agents) in exceptional cases.

z Chlorides and/or sulphates too high: Mixing with softened water (pH neutralized con- densate or water softened by ion exchanger). The conditioning of the coolant for liquid-cooled DEUTZ compact engines is performed by mixing an anti-freeze with corrosion protection inhibitors based on ethylene glycol into the water. Cooling system corrosion protection agent Health damaging nitrous amines form when nitrite-based cooling system corro- sion protection agents are mixed with amine-based agents! Cooling system corrosion protection agents must be disposed of in an environmentally friendly way.

In liquid-cooled engines, the coolant must be condi- tioned and monitored, otherwise the engine could be damaged by: The right water quality is important for conditioning the coolant. Clear, clean water within the following analysis values should always be used:
