Cooling system

6Specifications when working on the cooling system

Danger of scalding from hot coolant! Cooling system under pressure! Only open the cap when cool! The coolant must have a prescribed concentration of cooling system corrosion protection agent! Observe safety regulations and national specifications when handling cooling media. Observe the manufacturer's specifications for an external cooler. Dispose of leaking liquids properly and do not allow them to seep into the ground. Order coolant corrosion protection agent from your DEUTZ partner. Never operate the engine without coolant, even for a short time!

Checking the coolant level with an external cooler

●Fill in new coolant and vent the system according to the specifications of the cooling system manufacturer. ●Open the cooling system cap (1) carefully. ●The coolant level must always be between the MIN and MAX marks of the compensation tank! Fill up to the MAX mark if necessary. Check coolant additive concentration

●Open the cooling system cap (1) carefully. ●Check the coolant aditive concentration in the cooler/compensation tank (2) with a conventional antifreeze measuring device (1) (e.g. hydrometer, refractormeter). ●Necessary coolant additive concentration Coolant mixing ratio ( 40).

The corresponding test device can be ordered from your DEUTZ partner under the order no.: 0293 7499. 1

Emptying the cooling system

●Open cooler locking cap carefully. ●Place suitable collecting containers underneath. ●Remove the locking screw (1) in the crankcase. ●Drain coolant. ●Insert screw again with sealant. ●Close cooler locking cap.

Fill and ventilate cooling system

Danger of scalding from hot coolant! Cooling system under pressure! Only open the cap when cool!

●Open the cooling system cap (1) carefully. ●Loosen the cooler venting screw if necessary. ●Fill coolant up to the max. mark or filling limit. ●Switch on any available heating and set to the highest level so that the heating circuit is filled and vented. ●Close cooler locking cap. ●Run engine up to operating temperature (opening temperature of the thermostat). ●Switch off the engine. ●Check coolant level in cooled engine and top up to the MAX mark or filling level on the compensation tank if necessary.
