Check

1

Remove the coolant cap (1) from tank.

2

Insert the coolant tester tube (2) inside the coolant tank.

3

Press the coolant tester bellow (3) to fill the coolant in measuring chamber.

4

Close the knob (4) after coolant completely filled in the measuring chamber to restrict the return flow.

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

5

Check the reading on the measuring dial and find the coolant contraction or refill quantity.

GF20.00-Y-1000B

Follow the calculation in the reference document to find coolant contraction.

6

Add required quantity of coolant and tighten the coolant cap.
