Use 8T-5296 Test Group to check the concentration of the coolant.
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 filler cap in order to relieve the pressure. Remove the 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 every 38 L (10 US gal) of engine cooling capacity.
Refer to the Operation and Maintenance Manual, "Refill Capacities" for the capacity of the cooling system.
- Inspect the radiator cap gasket. Install a new radiator cap if the gasket is damaged.
- Install the radiator cap.
