Warning

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 of f”—simply make the correct connections and watch it happen. A typical exchange procedure may take only 10 minutes!

Relieve Cooling System Pressure

WARNING: Cooling systems that are hot, are under pressure. Working on a hot cooling system without first relieving the pressure will result in serious personal injury.

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.

Black Hose

(new coolant)

CAUTION: To prevent damage to the vehicle, test pressure must range BELOW the pressure indicated on the radiator cap, overflow cap, or vehicle specifications.

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.
