6.
Connect the Adapter Hose to the radiator overflow port to relieve radiator pressure. Watch
the System Vacuum Gauge and make sure the vacuum level increases and then stays
greater than 20 InHg. Carefully remove radiator cap. Use a shop rag over the cap when
removing to avoid injury in case there is still pressure. Remove the Adapter Hose.
7.
Place VCX Cone Adapter snugly into the radiator spout. Do not force the Cone Adapter
into the spout, the suction
pressure from the VCX should
secure it adequately. Verify that
the Cone Adapter Valve is in the
open position.
8.
Start the engine once fluid
starts to move through the
clear hose and into the VCX
Waste Coolant Tank. Verify
that the System Vacuum
gauge reads at least 22
InHg.
9.
Once the waste coolant
from the vehicle stops
flowing through the clear
hose, turn all of the panel
valves to Home Position
and turn the engine off.
DO NOT REMOVE CONE ADAPTER FROM THE RADIATOR!
Note: In some cases it may be necessary to pinch off the hose going from the radiator
neck to the overflow container. This is only necessary when the vacuum leaks
through this hose. The hose should be opened only after the Fill Radiator
procedure.
