OPERATING INSTRUCTIONS
To pressure check and/or fill a cooling system, first pick the correct cooling system adapter.
NOTE:
Spindle A screws into adapter 2 (white) for coolant reservoirs that have a reduced diameter neck inside.
PRESSURE / LEAK CHECK:
1. If system is empty or underfilled, add coolant and fluorescent dye (if desired), this will aid in the leak check process.
2. Connect the appropriate adapter to the cooling system.
3. Turn pressure regulator, round black knob (#1), completely out (counterclockwise).
4. Connect pressure regulator hose to adapter.
5. Close ball valve on pressure regulator then connect shop air to pressure regulator.
6. Slowly open ball valve on pressure regulator.
7. Turn round black knob (#1) on pressure regulator clockwise until desired pressure is reached.
8. When desired pressure is reached, turn black collar clockwise to lock.
9. Close the ball valve on the pressure regulator.
10. Inspect the cooling system for any external leaks in the hoses, radiator, water control valve, water pump, heater core,
cylinder head/intake manifold, coolant recovery/reserve tank.
NOTE:
If pressure reading decreases there could be an internal leak, check for coolant in the oil
TO REMOVE PRESSURE REGULATOR FROM SYSTEM:
1. Ensure that the ball valve is closed and disconnect shop air.
2. Connect one end of the pressure relief/fill tube (#9) to the regulator shop air connection and the other end into
container to capture any residual coolant from the system.
3. To relieve the pressure, slowly open the ball valve, turn black locking collar counter clockwise then black knob (#1)
counterclockwise and remove adapters.
REFILL SYSTEM USING VACUUM REFILL ADAPTER:
1. Connect the appropriate adapter to the system.
2. Connect the vacuum refill adapter to the to the adapter on the system.
3. Connect the fill tube (#9) to the vacuum refill adapter and place the other end into fresh coolant supply. Make sure
that the fresh coolant supply is at the same level or higher than the vacuum refill adapter.
4. Connect the shop air and slide the vacuum/fill handle to “vacuum” position.
5. Monitor the gauge reading on the vacuum fill adapter, when the vacuum stabilizes, slide the handle to the “fill”
position to draw in the fresh coolant. The cooling system is filled when the pressure gauge reads “0” PSI.
6. Remove the adapters, check to ensure proper coolant level.
