Use 8T-5296 Test Group to check the concentration of the Diesel Engine Antifreeze/Coolant (DEAC).
If necessary, add supplemental coolant additive.
| NOTICE |

|
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. |
- Slowly loosen the cooling system pressure cap in order to relieve the pressure. Remove the cooling system pressure cap.
- Add supplemental coolant additive. Drain some coolant from the radiator into a suitable container in order to allow space for the extra coolant additive.
Note: Always discard drained fluids according to local regulations.
- Add
0.24 L (.50 pint) of supplemental coolant additive for every38 L (10 US gal) of engine cooling capacity. - Inspect the gasket for the cooling system pressure cap. Replace the gasket if the gasket is damaged.
- Install the cooling system pressure cap.

Steam or hot coolant can cause severe burns. Do not loosen the filler cap or the pressure cap on a hot engine. Allow the engine to cool before removing the filler cap or the pressure cap. |
