The EBS Products Coolant Fluid Exchange Service system is a self-contained coolant extraction, flush and exchange service equipment that uses reverse flow through the cooling system. The hose adaptor set and equipment allows for chemical flushing and checking thermostat operation with the engine running. The engine is then turned off for the complete fluid exchange. The hose adaptor set covers 99 percent of all vehicles including commercial vehicles. New and used tanks (8-gal) are within the equipment with separate pumps.
