Warning

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.
Wear protective gloves, protective clothing and safety glasses.

Check

1

Remove the coolant cap (350) from tank

2

Insert the coolant tester hose (351) inside the coolant reservoir

3

Press the coolant tester bellow (352) to fill the coolant in measuring chamber

Mixture ratio for coolant

4

Close the measuring chamber knob (353) to restrict the return flow


Ensure coolant is completely filled in measuring chamber.
The measurement value chamber must be completely filled with fluid and entirely bubble-free. This is achieved by tapping on the housing.

5

Check the measurement value on the measuring dial and calculate coolant contraction
