Caution! Do not remove the expansion tank cap when the engine and radiator are hot. Hot liquid and steam may escape under high pressure.
1. Place a tray under the vehicle to drain the coolant.
2. Remove the expansion tank cap.
3. Remove the drain plug.
Caution! Store used coolant in a suitable container and dispose of it with used oil. Do not pour used coolant into the sewer.
4. Collect the liquid in a drain pan.
5. Remove all sludge and debris from the expansion tank. Follow step "Expansion tank" in this section.
6. Install the drain plug.
7. Add clean water to the expansion tank.
8. Fill the reservoir slowly until the top hose of the reservoir is above the water level. This will allow air to escape from the cooling system.
9. Start the engine.
10. Run the engine until the thermostat opens. The thermostat is open when both radiator hoses are hot to the touch.
11. Stop the engine.
12. Repeat steps 1 - 9 until the drain water is clear and free of coolant and rust.
Note: Do not use a mixture with a concentration greater than 60% antifreeze to 40% water. Above this concentration, the freezing point of the solution increases.
13. Fill the cooling system with a mixture of Dex-cool and water through the expansion tank. The mixture should be antifreeze at least 50%, but not more than 60%.
14. Fill the coolant to the MAX mark on the outside of the expansion tank.
