1. Turn the radiator cap counterclockwise and remove
it.
2. Loosen the radiator drain plug and drain the coolant
into a suitable container.
3. With the drain plug loose, flush the system with
running water.
4. Drain the system completely and retighten the drain
plug. Add the necessary amount of ethylene glycol-
based coolant and water to provide the required
protection against freezing and corrosion.
In extremely cold climates, add the necessary
amount of ethylene glycol-based coolant in
accordance with the instructions of the coolant
manufacturer.
5. Run the engine at idle with the radiator cap off.
Slowly add additional coolant if necessary.
6. At this point, wait until the engine reaches normal
operating temperature. Depress the accelerator two
or three times; then add coolant if required. Be
careful not to burn yourself.
7. Install the radiator cap. Inspect all connections for
leaks and recheck the coolant level in the reservoir.
Recheck again after a few days of driving and add
coolant as necessary.
