Radiator Pressure Tester & Vacuum Type Cooling System Kit (25PCS)

Description:

* Set for testing leaks in automotive cooling system and refill new coolant by creating a vacuum in cooling system.

* Includes various adapters for major vehicle brands on market

* Adapters and pump are made of light weight nylon 6-6

* Connectors(blue and black) are for testing pressure caps

* Includes a thermometer for extra safety

Specification:

Operation:

1. Create a vacuum in the cooling system

1. Drain coolant from the radiator
2. Hook the gauge underneath the car’s hood
3. Connect shop air to shop air connector(B)
4. Connect the conical adapter(8) or a suitable test cap(5 or 6) onto the radiator filler neck(as in Fig.1)
5. Turn on the air switch (C) and air control valve(E), while coolant control valve(G) remains off, to create a vacuum in the cooling system(as in Fig.2)
6. When the pressure falls into the range between -50 and -60 cmHg (-20 and -25inHg), turn off the air control valve (E) and then air switch(C)
7. Leave the gauge on the radiator for approximately 10 min to check if there are leaks in the cooling system before refilling new coolant.

2. Refill New Coolant

8. Connect the coolant hose(10) to the coolant hose connector(H).
9. Put the hose into a container filled with pre-mixed new coolant.
10. Turn on the coolant control valve(G) (while the air control valve(E) and air switch(C) remain off), coolant will be introduced into the radiator immediately (as in Fig.3).
11. The refilling process is completed when the gauge reads zero.
12. Remove residual coolant in the gauge before storage.

Cooling System Pressure Test

1. Choose a suitable adapter and screw the adapter onto the radiator filler neck.
2. Connect the pressure tester to adapter.
3. Pump pressure to the range between 10 and 15 psi (Fig.4).
4. Check if the gauge reading moves.

If it does, there could be leaks in the cooling system.

Attention: Don’t pump the pressure up to 35psi.

Radiator Cap Pressure Test

1. Connect the original radiator cap to one side of the connector, and a test cap on the other side (Fig.5)
2. Pump pressure to specified pressure on the cap.
3. When pumping pressure under the specified pressure, check if the gauge reading drops. If it does, there could be leaks on the cap.
4. When pumping pressure above the specified pressure, check if the radiator cap has the ability to release pressure. If it does not, the cap should be replaced.
