•914-1020: Has one extra adapter for GM and Ford group vehicles.
•914-1021: Has 19pcs adapters fitting universal cars.
•914-1022: Has another extra adapter, compared to 914-1020 for BMW and Mini 2008~present.
•Pressure pump can test leaks in the colling system by connecting an adapter to the radiator or recovery tank.
•For cooling system pressure test and refilling new coolant by creating vacuum in the cooling system.
•Includes a pressure pump, vacuum pump with a gauge, test cap connectors and adapters.
•Vacuum pump shortens the time of refilling new coolant by creating a vacuum, which eliminates the need to do time-consuming air bleeding.
•Connectors (black and blue) can test radiator cap condition.
Radiator Leakage Set:---
•Connect the pressure pump to radiator or recovery tank.
•Pump the pressure to the range between 10 and 15 psi.
•Check if the gauge pointer stays or drops.
•If it dropped, there could be leaks in the radiator.
Pressure Cap Function Test:---
•Connect the original pressure cap on one side of the connector and a pressure test cap on the other side.
•Pump the pressure for testing.
•Before reaching the high limit of the cap: check if the pressure pointer drops. If it drops, there could be leaks in the cap.
•After exceeding the high limit of the cap: Check if the cap has the ability to release pressure. If the cap did not release, the cap could be dysfunctional.
Create A Vacuum:---
•Drain the coolant in the radiator.
•Connect an air line to the top of the vacuum pump.
•Turn the switch and air valve ON and turn the coolant valve off to create a vacuum in the radiator.
•When the pressure falls into the range between -50 and -60cmHg (-0.6 to -0.8 bar), turn off the switch and valve and then disconnect the air line.
Refill The Coolant:---
•Connect the coolant hose to the connector below the gauge.
•Put the other end of the hose into a container filled with pre-mixed coolant.
•Turn ON the coolant valve, while leaving other switch and valve off.
•When the gague reads ZERO, the refilling is completed.
