Flushing (with White Vinegar)
A. Place the LCS on its side.
B. Attach a 1ft tube to input port.
C. Mix a 50/50 solution of vinegar and hot tap water.
D. Pour the solution down the input port using a funnel.
E. Connect the end of the 1 foot tube to the output port.
F. Let stand until cool.
G. Turn the LCS upside down so the solution falls into the tube and then turn the LCS onto its side to send the solution the other way.
H. Apply heat to the water block with a heat gun or hot air tool.
I. Allow The LCS to cool.
J. Repeat steps C-I 2-3 times.
K. Disconnect the 1ft tube from the either port and attach another hose.
L. Connect the input port hose to your faucet via adapter and turn on the faucet (I used a flex tube bought at Advance Auto Parts.)

M. Turn off the faucet and repeat step K with the faucet connected to the output port.
N. Repeat steps K & L 2-3 times or until clear water can be seen.
O. Using a funnel, pour in 100% distilled water into the input port until it flows out the output port.
Refilling
Because all of the filling ports are crimped off (and have epoxy covering them) I have come up with a reliable alternate method of filling the system:
A. Go ahead and reattach the cooling pump assembly with the 6 screws.
B. Measure and cut a 3 inch piece of Vinyl tubing and attach it to the "Z” Tube. (Make sure you still have the restrictor!)
C. Slide two loose hose clamps over the Vinyl tubing and connect the tube to the pump.
D. Place a hose clamp on each side and tighten them down (The part with the screw should be down if you want to put your “G5” cover back on.)
E. Cut a 4.5 inch piece and attach it to the radiator fitting.
F. Place 1 foot piece of tubing on the pumps outlet port
G. Place the LCS in your sink with the radiator facing down.

H. Fill a spare container with 75% distilled water and 25% Dex-Cool and stir

I. Fill the system with the coolant you just made using the 4.5 inch hose connected to the radiator using a funnel, continue to pour coolant into the funnel until you see the coolant begin to flow out of the pumps output port. (The smaller hose should be completely full of coolant at this point. Also, if the coolant doesn’t flow on its own then use the hand vacuum pump on the pump’s output port.)
J. Place two hose clamps on the 4.5 inch hose.
K. Now, place your finger over the pump’s output port and fill the 4.5 inch hose up to the top.
L. Connect the hose to the pump and bench check the system
M. If the bench check passes then tighten the clamps
Bleeding
Bleeding isn’t always necessary, you may notice a small bubble in each tube after the filling procedure and that’s alright. But, if you have multiple bubbles or large bubbles or if the pump makes a grinding noise for longer than 30 seconds you need to bleed it.
A. Place The at 45 degree angle as pictured and either disconnect the 4.5 inch hose from the pump side or cut the hose with a razor and place a new hose on the radiator.

B. Now, place your finger over the pump’s output port and fill the 4.5 inch hose up to the top.
C. Connect the hose to the pump and bench check the system.
D. If the bench check passes then tighten the clamps.
