(see below) “Making Determinations” ONLY APPLY to HD NF Extended Life COOLANT (NF OAT). Confirm HD NF OAT color could be RED or YELLOW. • Never use SCA filters with current HD NF Extended Life Coolant (NF OAT). • Make all fluid determinations before making concentration or level adjustments. NOTE: When using test strips follow test instructions on the test strip card or bottle. (When using Prestone test strips it is advisable to use the color standards on the cards) Warning: Do not open the cooling system if engine is hot! Wear gloves, if skin contacts fluid wash immediately. TEST INSTRUCTIONS Collect coolant sample from the radiator or petcock at room temperature. Remove a test strip from the bottle. DO NOT touch the pads at the end of the strip. Dip the strip in coolant sample for 2 seconds. Remove and shake strip briskly to remove excess liquid. Wait 45 seconds, then match to the BLACK numbers on the color chart if the coolant color is YELLOW or match to the RED numbers on the color chart if the coolant color is RED. Complete color matching within 20 seconds. Prestone Command test strip AFC240 should only be used for red or yellow NOAT or NF OAT HD coolants. Making Determinations: 1. If the pH level is below 7.0: • Full fluid analyses are required, or flush the cooling system with water and refill with new Prestone Command ® HD Extended Life Antifreeze/Coolant or Prestone Command ® HD NF Extended Life Antifreeze/Coolant. • If the cooling system shows visible signs of contamination flush the system with Prestone Command ® Heavy Duty Cooling System 2in1 Flush & Degreaser, then flush with water to remove chemical flush solvent and refill with Prestone Command ® HD Extended Life Antifreeze/Coolant or Prestone Command ® HD NF Extended Life Antifreeze/Coolant. 2. If the pH level is between 7.0 - 10.0 and the nitrite level is below 500: • The coolant is OK. • If needed top off with the correct amount of Prestone Command ® HD NF Extended Life Antifreeze/Coolant or water to adjust the level and concentration. 3. If the pH level is between 7.0 – 10.0 and the nitrite level is above 500: • Flush the cooling system with water and refill with new Prestone Command ® HD NF Extended Life Antifreeze/Coolant. • If the cooling system shows visible signs of contamination flush the system with Prestone Command ® Heavy Duty Cooling System 2in1 Flush & Degreaser, then flush with water to remove chemical flush solvent and refill with Prestone Command ® HD NF Extended Life Antifreeze/Coolant. 4. If the pH level is above 10: • Flush the cooling system with water and refill with new Prestone Command ® HD NF Extended Life Antifreeze/Coolant. • If the cooling system shows visible signs of contamination flush the system with Prestone Command ® Heavy Duty Cooling System 2in1 Flush & Degreaser, then flush with water to remove chemical flush solvent and refill with Prestone Command ® HD NF Extended Life Antifreeze/Coolant.
