4 © 2002 4.3 Coolant Operating Media Cooling System Protective DEUTZ cooling system protective agents can be obtained under order number 01011490 (5 litres) or 1221 1500 (210 litres). These are nitrite-, amine- and phosphate- provide effective protection against corrosion, cavitation and freezing. If the above-mentioned cooling system agents are not available, the following products can be used in exceptional cases. Product description AVIA Antifreeze Extra Glysantin G 48 DEA DEA radiator antifreeze SHELL SHELL GlycoShell The concentration of the cooling system protective liquid in the coolant may not fall below/exceed the following limits: Cooling system protective liquid Water max.
45 Vol.% 55% min. 35 Vol.% 65% For the quantity, see table overpage and information in section 9.1. Other cooling system protective liquids, e.g. chemical corrosion inhibitors, can, in exceptional circumstances, be used in the coolant, in consultation with DEUTZ Service. Order the cooling system protective liquid from: DEUTZ Service Cooling system protective liquids must be disposed of in accor- dance with environmental regulations. The preparation and monitoring of coolant in liquid-cooled engines is especially important because corrosion, cavitation and freezing can lead to engine damage. The coolant is prepared by admixing a cooling system protective liquid with the cooling water.
The cooling system must be monitored regularly (see 5.1). The water level and the cooling system protective liquid concen- tration should both be checked. The cooling system protective concentration can be checked with a commercially available tester (e.g. gefo glycomat ® ). When nitrite-based cooling system protective liquids are mixed with amine-based liquids, harmful nitrosamines are formed. 4.3.1 Water Quality for Coolant Preparation 4.3.2 Coolant Preparation The values given below must not be exceeded. A test kit (order number 1213 0382) can be obtained from DEUTZ Service to check the quality of the water available. Water quality min. max.
