Operating Manual
Before using the coolant exchanger, read, understand, and follow the safety precautions and operating
instructions outlined in this manual. This equipment must be operated by qualified personnel – the operator must be
familiar with vehicle cooling systems, coolants, and the dangers they present.
– If the operator cannot read English, operating instructions and safety precautions must be read and discussed in the
operator's native language.
– Si el operador no puede leer inglés, las instrucciones de operación y las precauciones de seguridad deberán leerse y
comentarse en el idioma nativo del operador.
– Si l'utilisateur ne peut lire l'anglais, les instructions et les consignes de sécurité doivent lui être expliquées dans sa langue
maternelle.
Do not drink antifreeze or solution. Avoid inhaling mist or hot vapors. (Ethylene glycol base.) If swallowed, drink
two glasses of water; induce vomiting; and call a physician. If inhaled, move to fresh air and call a physician. Use the unit
in locations with mechanical ventilation that provides at least four air changes per hour. If accidental system discharge
occurs, ventilate the work area before resuming work.
Do not store ethylene glycol based solutions in open or unlabeled containers. Ethylene glycol causes birth defects
in laboratory animals; solution may taste pleasant to animals, but is poisonous to them.
Contact with antifreeze/coolant may cause injury. Hot antifreeze/coolant can burn skin and injure eyes. Wear
protective equipment, including safety goggles and gloves, when operating this equipment. If contact with eyes occurs,
call a physician immediately, and flush eyes with cold water for 30 minutes. If contact with skin occurs, thoroughly wash
area with soap and water.
Vehicle cooling systems which are hot, are under pressure — opening a hot system, except as described in this
manual, can cause an uncontrolled release of engine coolant. Do not open the radiator cap, and do not remove hoses
from a hot system except as directed in this manual.
Do not pressurize the vehicle cooling system above its pressure rating. Doing so may result in cooling system failure
and the release of engine coolant.
Never run a vehicle engine without adequate ventilation. Breathing vehicle emissions can cause sickness, injury, or
death.
Working in the vicinity of a lead-acid or other automotive battery is dangerous. Wear eye protection. NEVER smoke,
or allow a spark or flame in the vicinity of a battery. Batteries generate explosive gases during normal battery operation.
This equipment is not designed for any other purposes than testing cooling systems and exchanging used antifreeze/
coolant with new or recycled product.
The operator is responsible for complying with any and all applicable laws and regulations governing the use of this type
of equipment, as well as disposal of used antifreeze/coolant and used equipment and components.

Introduction
The 75700 COOLXCHANGE offers everything you need to quickly remove and replace coolant in a vehicle:
drain and fill, and pressure test for leaks. Two external, new coolant supply tanks allow on-board storage of
two different coolant types.
No electricity is needed—shop air powers the unit. No hoses to cut. No additional ventilation is required—the
service procedure is performed with the engine off. The coolant transfer process is “hands off”—simply make
the correct connections and watch it happen. A typical exchange procedure may take only 10 minutes!

Relieve Cooling System Pressure
On some systems it is necessary to allow the cooling
system to cool before servicing the vehicle. On
vehicles that have a radiator cap, it is possible to relieve
pressure by drawing a vacuum on the overflow port.
System Inspection
Before starting the service procedure, verify :
•
the 75700 unit is connected to a supply tank
holding the correct amount and type of new
coolant for the vehicle being serviced.
•
the waste coolant tank has enough capacity to
exchange the desired amount of coolant.
Note: Running the unit with a full waste tank will
degrade the performance of the unit.
•
the vehicle ignition is in the OFF position.
•
valves 1 and 2 on the 75700 unit are OFF.
•
the valve on the black hose is open. See Figure 3.
•
the filter screen on the clear hose is clean.
Relieve Pressure on a Hot System
that has a Radiator Cap :
1. Remove the vehicle’s overflow tank hose from
the coolant overflow barb on the radiator neck.
2.
Two sizes of siphon tubes have been included with
the 75700 unit. See Fig. 4. Select the siphon tube
which most closely matches the size of the coolant
overflow barb on the vehicle’s radiator neck.
3. Slide the siphon tube onto the coolant overflow
barb on the radiator neck.
4. Connect the coupler end of the siphon tube to the
clear hose from the 75700 unit. See Figure 5.
5. Turn both valves on the unit to VACUUM. As the
valve in the radiator cap releases pressure,
coolant may be seen in the siphon tube.
6. After pressure is relieved, turn both valves OFF.

Lower the Coolant Level
1. After the cooling system has been depressurized
or cooled down, CAREFULLY remove the
coolant reservoir cap and the radiator cap.
2. With the coupler end of the siphon tube
connected to the clear hose (waste coolant) from
the 75700 unit, insert the other end of the siphon
tube into the coolant reservoir.
3. Turn both valves on the unit to VACUUM to
empty the coolant reservoir.
4. Insert the siphon tube into the radiator, and lower
the coolant level in the radiator to a level below
the upper radiator hose.
5. Turn both valves on the 75700 unit OFF.
6. Remove the siphon tube from the radiator, and
disconnect it from the clear hose.
7. Reinstall any disconnected hoses on the vehicle.

The upper radiator hose may be disconnected either
where it connects to the radiator or where it
connects to the engine, whichever is most
convenient on the vehicle being serviced.
1. Disconnect the upper radiator hose from the
radiator or the engine.
2. Insert a step adapter into the radiator hose. See
Figure 7.
3. Select an adapter hose that has the same inner
diameter as the radiator hose. Clamp a step
adapter to the hose, and then clamp the assembly
to the hose barb where the upper radiator hose
was connected.
4. Connect the clear hose (waste coolant) to the step
adapter leading into the radiator.
5. Connect the black hose (new coolant) to the step

Pressure Test
This procedure checks the coolant system for leaks.
A drop in pressure indicates a leak in the system
that must be repaired before refilling the system
with coolant.
IMPORTANT: For correct operation of the
75700 unit, adjust Valve 1 and Valve 2 in the
sequence specified in these instructions.
1. Turn the regulator on the 75700 control panel
counterclockwise (CCW) to lower the test
pressure. See Figure 10.
Note: Adjusting the regulator requires pulling up
on the regulator knob, and then turning the knob.
2. Turn Valve 1 to PRESSURE TEST.
3. Turn Valve 2 to PRESSURIZE.
4. Adjust the regulator clockwise to the correct test
pressure.

5. Turn Valve 2 to HOLD.
6. Observe the pressure gauge on the control panel:
•
a constant pressure reading indicates no leaks
in the system;
•
a drop in pressure indicates a leak in the system
that must be repaired.
Note: The cooling system may need to be
pressurized more than once to equalize test
pressure throughout the system.
7. If a leak must be repaired, turn both valves to
VACUUM to relieve pressure. Perform repairs,
and repeat the Pressure Test.
If no repairs are needed, proceed to the Exchange
Procedure.

1. Note the level of coolant in either the sight gauge
for the waste coolant tank or the new coolant
tank on the back of the unit.
2. Turn Valve 1 to EXCHANGE.
3. Turn Valve 2 to EXCHANGE.
4. Watch the fluid level indicator. After exchanging
the correct amount of coolant (based on the
vehicle’s cooling system capacity), turn Valve 1
OFF. Turn Valve 2 OFF.
Note: The coolant running through the waste
hose at this time should be clean. If not, continue
the exchange process until the coolant running
through the waste hose is clean.
Complete the Exchange Process
This procedure will top off the coolant in the
radiator and fill the coolant overflow reservoir.
1. Remove the step adapters and hoses. Reassemble
the upper radiator hose to the vehicle.
2. Release any pinched-off hoses.
3. Connect the siphon tube to the black hose (new
coolant).
4. Remove the radiator cap and/or coolant reservoir
cap.
5. Close the valve on the end of the black hose
(new coolant). See Figure 11.
6. Turn both valves on the 75700 to EXCHANGE.

Tech Tip
Some vehicles require a different vehicle hookup
due to the way the coolant flows through the
system.
If, during the exchange process, you can’t hear
the pump running, and the flow rate is slower than
usual, it may be necessary to change the way the
hoses are connected to the vehicle.
1. Connect the clear hose (waste coolant) to the
step adapter leading into the engine.
2. Connect the black hose (new coolant) to the
step adapter leading into the radiator. The valve
on the black hose should be OPEN.
3. Leave the coolant overflow hose and any other
hoses connected to the coolant reservoir
pinched off.
4. Repeat the Exchange Process.

Maintenance
Changing Supply Tanks
This procedure outlines how to switch supply tanks
so the 75700 will exchange the correct type of
coolant for the vehicle being serviced.
1. Disconnect the supply hose from the dip tube
cap. See Figure 12. Remove the dip tube cap.
2. Connect the siphon tube to the black hose (new
coolant).
3. Insert the other end of the siphon tube into the
supply tank.
4. Turn the valves on the 75700 to EXCHANGE
until coolant stops flowing in the siphon tube.
5. Turn the valves on the 75700 OFF.
6. Connect the dip tube cap to a supply tank
containing the type of coolant that is correct for
the vehicle being serviced.
7. Connect the supply hose to the dip tube cap.
Emptying the Waste Tank
Running the 75700 unit with a full waste tank will
degrade the performance of the unit.
1. Connect the siphon tube to the black hose (new
coolant).
2. Insert the other end of the siphon tube into a
waste barrel.
3. Turn both valves on the 75700 to EMPTY
WASTE.
4. Watch the sight glass for the waste tank. See
Figure 13. Empty the tank completely.
IMPORTANT: Do not leave any waste
coolant in the black hose because it
functions as the new coolant hose when
servicing a vehicle.
