9CL-70190 - Cooling System Leakage Tester and Vacuum-Type Coolant Refilling Kit (26 pcs)

•  For cooling system pressure test and refilling new coolant by creating vacuum in the cooling system.
•  Vacuum pump shortens the operation, eliminating the need to perform time-consuming air bleeding.
•  Contains 17 test caps (No. 3 – 19) and a universal adapter suitable for universal vehicles.
•  Two connector tubes (black and blue) are provided to test the functionality of the original radiator caps.
•  Stock Ref. No. 9CL-71019

CREATE A VACUUM IN THE COOLING SYSTEM

1.  Drain coolant from the radiator.
2.  Hook the gauge underneath the car’s hood.
3.  Connect an air line to air supply.
4.  Connect the universal con-shaped adapter (No. 10) or suitable adapter onto the radiator filler neck.
5.  Turn on the air switch and air control valve, while coolant control valve remains off, to create a vacuum in the cooling system.
6.  When the pressure falls into the range between -50 to -60 cmHg (-20 and -25 inHg), turn off the air control valve and the air switch.
7.  Leave the gauge on the radiator for approximately 10 minutes to check if there are leaks in the cooling system before refilling new coolant.

REFILL NEW COOLANT

1.  Connect the coolant hose (No. 12) to the coolant hose connector.
2.  Put the other end of the hose into a container filled with pre-mixed new coolant.
3.  Turn on the coolant control valve (while the air control valve and air switch remain off), coolant will be introduced into the radiator immediately.
4.  The refilling process is completed when the gauge reads zero.
5.  Before putting the gauge back to the case, remove the residual coolant in the gauge.

COOLING SYSTEM LEAKAGE TEST

1.  Choose a suitable adapter and screw it onto the radiator filler neck.
2.  Connect the pressure tester to the adapter.
3.  Pump pressure to the range between 10 and 15 psi.
4.  Check if the gauge reading moves. If it does, there could be leaks in the cooling system.

Attention: Do not pump the pressure up to 35 psi.

RADIATOR CAP LEAKAGE TEST

1.  Connect the original radiator cap to one side of the connector, and a pressure test cap on the other side.
2.  Pump pressure to specified pressure on the cap.
3.  When pumping pressure under the specified pressure, check if gauge reading drops. If it does, there could be leaks in the radiator 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.
