Procedures for Heavy Duty Vehicles

  1. Drain the radiator. Removal of the bottom radiator hose usually yields additional fluid.
  2. Drain the block. Search carefully for drain locations that may be at the bottom of the oil cooler, or on the lower region of the EGR cooler. Look for drain locations at the thermostat housing.
  3. Drain the heater circuit. Disconnect the lines to the heater and gently blow compressed air in both directions. NOTE: When blowing out the heater, set the temperature control to "max". Also, some HD vehicles require the ignition key to be "on" in order to have flow through the heater. It is helpful to insert new Evans Prep Fluid into the heater and then blow it out to chase out old coolant that may be present. NEVER FLUSH WITH WATER.
  4. Make sure the expansion tank is empty.
  5. If there is an overflow bottle, empty it completely.
  6. Drain any ancillary cooling circuits (e.g., fuel heater and brake air compressor circuits) and gently blow them out with compressed air.
  7. Use a gallon of Evans Prep Fluid to flush parts of the cooling system suspected to harbor residual coolant. The garden sprayer is particularly handy for introducing Prep Fluid into such areas. (The nozzle can be unscrewed and a ¼" ID hose slipped onto the wand.)
  8. If the engine is equipped with a coolant filter, remove the filter and replace it with one that does not introduce coolant additives.
  9. Reconnect all circuits and close any drains.
  10. Fill the system completely with Evans Heavy Duty Coolant.
  11. Replace the radiator cap.
  12. Apply DO NOT ADD WATER OR WATER BASED COOLANT warnings.
  13. Run the engine until it is warm and the thermostat(s) open. After the coolant has circulated completely, prepare to test the coolant water content.
  14. Calibrate the refractometer. Using new Evans Heavy Duty Coolant, place a drop on the refractometer glass and check the reading. If it does not read 55.7, use the screwdriver provided to set it to 55.7.
  15. After there has been thorough circulation of the coolant through all parts of the cooling system, including the radiator and the heater core, obtain a coolant sample for the refractometer from a "well-mixed" location. The reading should not exceed 54.4 Brix, which corresponds to 3% water.
  16. If the water exceeds 3%, some coolant may have to be drained and replaced with new Heavy Duty Coolant. Also, you can try this: Operating with the pressure cap removed will cause evaporation of water from the coolant when the coolant is hot. This method may be attempted as a means to lower the water content. The pressure cap should be returned to close the system once the water content is acceptable.
