Do not exceed the recommended six percent supplemental coolant additive concentration. Excessive supplemental coolant additive concentration can form deposits on the higher temperature surfaces of the cooling system, reducing the engine's heat heat transfer characteristics. Reduced heat transfer could cause cracking of the cylinder head and other high temperature components. Excessive supplemental coolant additive concentration could also result in radiator tube blockage, overheating, and/or accelerated water pump seal wear. Never use both liquid supplemental coolant additive and the spin-on element (if equipped) at the same time. The use of those additives together could result in supplemental coolant additive concentration exceeding the recommended six percent maximum. |

- Loosen the filler cap. Relieve the pressure. Remove the filler cap.
- Drain the coolant from the system, if necessary. Install the cooling system additive.
- Add 0.24 L (0.253 qt) of additive for every 38 L (10 US gal) of cooling system capacity.
- Inspect the radiator cap gasket. Replace the radiator cap if the gasket is damaged.
- Start the engine and check for leaks. Allow the coolant level to stabilize.
- If necessary, add premixed coolant. The coolant should be in a range of 13 mm (0.5 inch) below the bottom of the filler pipe. Install the filler cap.
