– Fit the cooling system testing device - V.A.G 1274 B- with
adapter -V.A.G 1274/8- onto the coolant expansion tank.
– Using the hand pump of the testing device generate an over‐
pressure of approx. 0.1 MPa (1.0 bar).
WARNING
Risk of scalding!
♦ Before the cooling system testing device - V.A.G 1274 B-
is separated from the connecting hose or the connecting
piece - V.A.G 1274 B/1- , the existing pressure must ab‐
solutely be released.
♦ For this step, press the pressure relief valve on the cooling
system testing device - V.A.G 1274 B- and hold it pressed
until the pressure gauge indicates the value »0«.
– If the pressure drops determine leak positions and repair.
Check pressure relief valve in cap.
– Fit the cooling system testing device - V.A.G 1274 B- with
adapter -V.A.G 1274/9- onto the cap.
