9CL-70193 - Cooling System Leakage Tester and Vacuum-Type Coolant Refilling Kit (29 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 20 test caps (No. 3 – 22) and a universal adapter for universal vehicles, including a No. 22 test cap for BMW and Mini.
- Two connector tubes (black & blue) are provided to test the functionality of the original radiator caps.
- Stock Ref. No. 9CL-7101923
CREATE A VACUUM IN THE COOLING SYSTEM
- Drain coolant from the radiator.
- Hook the gauge underneath the car’s hood.
- Connect an air line to air supply.
- Connect the universal con-shaped adapter (No. 10) or suitable adapter onto the radiator filler neck.
- Turn on the air switch and air control valve, while coolant control valve remains off, to create a vacuum in the cooling system.
- 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.
- 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
- Connect the coolant hose (No. 12) to the coolant hose connector.
- Put the other end of the hose into a container filled with pre-mixed new coolant.
- Turn on the coolant control valve (while the air control valve and air switch remain off), coolant will be introduced into the radiator immediately.
- The refilling process is completed when the gauge reads zero.
- Before putting the gauge back to the case, remove the residual coolant in the gauge.
COOLING SYSTEM LEAKAGE TEST
- Choose a suitable adapter and screw it onto the radiator filler neck.
- Connect the pressure tester to the adapter.
- Pump pressure to the range between 10 and 15 psi.
- 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
- Connect the original radiator cap to one side of the connector, and a pressure test cap on the other side.
- Pump pressure to specified pressure on the cap.
- When pumping pressure under the specified pressure, check if gauge reading drops. If it does, there could be leaks in the radiator cap.
- 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.
