Gauge Could turn almost 180°
Radiator test adaptor Two application provides more accurate fitting
  1. universal cone radiator cap
  2. specific radiator cap
on/off button User select if the air goes

2.  Instruction of radiator pressure tester
2.1 check leakage in radiator system with radiator caps (material-Nylon 66)
Step 1: Remove the original radiator cap while the engine is cold.
Step 2: Choose a test cap suiting the connection type onto the radiator. Screw the cap onto the radiator opening(Fig.1).
Step 3: Connect the pump to the test cap through the quick coupling at the hose end.
Step 4: Pump until pressure is approximately 10~15psi(Fig.2). If the gauge pointer perfectly efficient; if the gauge goes down and no fluid discharges can be located, check whether the engine head gasket is worn. (CAUTION: please avoid the pressure up to the 35psi)
Step 5: Finally, release pressure through the button next to the quick coupling, and put away the device, after removing any fluid or dirt.
2.2 Check leakage on original radiator cap
Step 1: Choose the #2A or #2B with available steel radiator.
Step 2: Work the hand pump for few times, and then check the gauge reading for testing leakage. (Fig. 3)
Step 3: Follow the pressure standard shows on original radiator cap.

3.  Instruction of vacuum purge & refill tool
3.1 Purge the air in radiator
Step 1: Please empty water from the radiator as clear as possible.
Step 2: Raise the vehicle bonnet and hand the hook in available position.
Step 3: Connect the universal radiator rubber adaptor provided or suitable radiator cap on radiator. (see fig. 4 & 5)
Step 4: Ensure the switch No.3 is ON, No.7 is OFF. (see fig. 6)
Step 5: Connect air line. Press button “ON” to allow the air goes (see fig. 7). Turn switch No.3 “OFF” when the pressure reaches 20-25 inHG (50-60cmHG) (see fig. 8). Then press button “OFF”.

3.2 Refill the Coolant
Step 1: Connect the coolant hose.
Step 2: It is necessary to ensure the No.3 is “OFF” before refilling coolant, then ensure coolant hose is filled with coolant.
Step 3: Turn No.7 “ON” to allow the coolant sucked into radiator. (see fig. 9)
Step 4: The work is done when the needle points will be back to “zero.”

Note: Please check if the radiator is fully filled with coolant or not. If not, please fill the coolant by yourself until the radiator is full of coolant.
