Cold Car / Reverse Flow Service Method: Step 3b – Standard Coolant Exchange
1.Fill the New Coolant Tank with the correct amount of the proper type of coolant. It is recommended that the New Coolant Tank be filled with at least the rated capacity of the vehicle’s cooling system (plus the prime level) and the best practice is to fill
2.Place the Control Valves in the following positions: “Pump From” New Tank; “Pump To” Vehicle. Connect the Black Service Hose to the Cross Flow Adapter closest to the thermostat, with the Red Service Hose connected to the other Cross Flow Adapter.
3.Turn the pump ON while monitoring the System Pressure Gauge. It will take approximately
4.The pressure of the fluid will drop as it passes the thermostat and will circulate at about half the rate required to open the thermostat. If pressure builds too high, it will open the radiator cap and fluid will flow into the overflow container. Monitor the overflow container fluid level during the cleaning process to avoid pressure issues and spillage.
5.Throughout the service, monitor the Sight Glass. When all cleaner solution/old coolant mixture
has been forced out of cooling system and replaced by new coolant, the coolant exchange process is complete.
6.After viewing new coolant in sight glass, turn pump OFF and disconnect the Red Service Hose. The vehicle will be full of new coolant.
7.To provide a clean and easy disconnect process, reverse the
8.Remove the overflow container lid and, if needed, vacuum out any remaining dirty fluid utilizing the flexible pick up tube (included with unit) attached to the Black Service Hose. Use the following valve arrangement: “Pump From” Vehicle; “Pump To” Processing Tank.
9.To fill the overflow container and
10.Replace the radiator cap and start the vehicle to ensure proper operation. Check for any system leaks and, after vehicle reaches operating temperature, ensure all fluids are at proper levels. The service is complete.
