Hi evolution09,

Drain the coolant by releasing the drain plug at radiator. Unloosen the bleeder hole and plug in a garden hose and let water flow through pushing out what you wish to get out.

Reinstall drain plug and fill with water and close bleeder bolt, run engine with radiator cap off till thermostat opens and repeat draining process.

When filling in coolant, do not close radiator cap, run engine and keep topping up till it cannot take in any more coolant. Stop engine and restart till air has been bled from system.
