DIRECTIONS FOR SERVICE REFILL: Refer to the owner’s manual for cooling system capacity. If the cooling system is dirty we recommended using Nulon Radiator Flush before using this product. 

  1. If the system is clean, ensure the engine is switched off, turn the heater on and drain the old coolant (when cool) by removing the drain plug or bottom radiator hose. 
  2. Replace drain plug or bottom radiator hose. 
  3. Add NULON RADIATOR CORROSION PROTECTOR to the radiator first then top-up with clean, soft or demineralised water. (Makes up to 15 Litres)
  4. Check the coolant level is correct when system is cool.
