USE OF THE EVACUATION PUMP:
|
WARNING:
Automotive cooling systems can be under pressure and extremely hot. Allow the vehicle's
cooling system to cool down and use extreme caution when removing caps and hoses. Consult
the vehicle manufacturer for recommended procedure on removing the radiator cap.
1. Squeeze the vehicle's upper radiator hose to determine the amount of pressure in the system. If the
hose is hot and hard, allow the cooling system to cool down before proceeding.
2. Carefully remove the vehicle's radiator cap.
3. Insert the Plastic Wand on the RED Hose into the radiator. Turn the CSC10R Evacuation Pump (the
switch is located on the front bevel of the unit) and remove the liquid from the radiator until the
liquid level is below the UPPER radiator hose (approximately two quarts). Turn off the Evacuation
Pump and replace the radiator cap.

CAUTION
Do not remove too much liquid from the radiator.
Allowing air to enter the LOWER radiator hose can
result in damage to the vehicle's engine.

CAUTION
Never allow the Evacuation Pump to operate without
liquid. Running the pump dry will cause premature
wear or damage to the pump and is not covered under
warranty.
4. Locate the vehicle's coolant overflow bottle and remove its cap. Insert the Plastic Wand on the RED
Suction Hose into the overflow bottle, turn on the Evacuation Pump, and remove as much liquid as
possible. Turn off the pump and return the RED Suction Hose to its clip. Replace the cap on the
overflow bottle.
HINT: If the overflow bottle contains sludge, loosen it with water sprayed from a hose.
ATTACH THE CSC10R TO THE VEHICLE - CONVENTIONAL COOLING SYSTEMS:
1. Loosen the hose clamp that holds the UPPER radiator hose to the radiator. Use a nut-driver,
screwdriver, or hose clamp pliers (depending on the type of clamp) to loosen the clamp.
2. Pull loose and remove the UPPER radiator hose from the vehicle's radiator. Be careful not to damage
the radiator inlet or hose while removing.
