Instruction
Cooling System Vacuum Purge & Refill Kit

Ref no. Description
1 Dual calibrated gauge 0 to -76 cmHg (0 to -1 bar)
2 Hanging hook (600mm)
3 Vacuum tap
4 Air inlet
5 ON/OFF Switch
6 Bleeding hose connector
7 Coolant suction tap
8 Coolant suction hose connector
9 Adaptor connector
10 Hose (500mm)

Step 1 Ensure coolant is drained from cooling system and all hoses are secured
Step 2 Select the suitable adaptor and fit it to vehicle
Step 3 Ensure the vacuum purge unit is in the off position and all taps are closed (Fig 01)
Connect the air bleeding hose and suction hose to the unit and connect to the vehicle (Fig 02)
Insert the air bleeding hose into an empty container to capture any remaining coolant that may be expelled
Fully submerged the coolant suction hose into the new coolant container
NOTE: Refer to the manufacture’s specifications for coolant ratio and capacity. The suction hose must be fully submerged at all times to prevent air from entering
Step 4 Switch the unit to the ‘ON’ position and open the vacuum tap (3)
Monitor the vacuum gauge until the pressure reaches around -60 cmHg (Fig 03)
Once it has reached it’s maximum, close the vacuum tap and switch the unit to the ‘OFF’ position (5)
Step 5 Once vacuum phase is completed with the vacuum tap in the closed position and the unit is switched ‘OFF’
Slowly turn the suction tap (7) to the open position, new coolant will begin to draw from the suction hose into the vehicles cooling system
It will automatically stop once the vehicles cooling system is full and the gauge needle is steady
Step 6 Close suction tap
Disconnect the workshop supply line and disconnect from vehicle
Check coolant level and top up if necessary
Coolant Pressure Testing

Ref no. Description
1 Dual calibrated gauge 0 – 35psi (0 – 2.5 bar)
2 Hand pump
3 Body
4 Hose (600mm)
5 Relief valve
6 Adaptor connector
Step 1 Remove the radiator cap from vehicle and top up coolant level if necessary
Caution: Do not open vehicle’s radiator cap when it is hot
Step 2 Select the correct test cap adaptor and connect to the vehicle
Step 3 Connect the pressure pump to the adaptor and ensure the connections are fitted correctly to avoid false reading
Begin to pump pressure into the vehicle’s cooling system between 10 – 15 psi
NOTE: Do exceed recommended pressure as it may further damage the vehicle’s cooling system. Refer to your workshop manual for correct pressure rating
Step 4 Inspect for coolant leaks while the cooling system is under pressure
If a leak is detected the pressure gauge will decrease as it looses pressure
Keep topping up the pressure to ensure the vehicle’s cooling system stays under pressure while inspecting for leaks
Step 5 Once complete depress the pressure relief valve (5) until the pressure gauge reads zero and disconnect from vehicle
Radiator Cap Testing (Bayonet type)
Step 1 Remove the radiator cap from vehicle
Step 2 Select the correct size radiator cap test adaptor
Step 3 Connect adaptor to pressure pump and the radiator cap to the adaptor
NOTE: Before testing check seals and condition of radiator cap
Step 4 Begin to pump to recommended pressure
NOTE: Check radiator cap or manufacture’s manual for pressure rating
Step 5 Once completed depress relief valve and disconnect cap
