Some have a Drain Cock on the Driver side bottom, facing the engine. Some don't & the Lower Hose needs to be removed to drain

 

Remove the coolant pressure cap.

Place a drain pan under the drain cock.

Open the radiator drain cock.

Drain the cooling system.

If a complete engine block drain is required, remove the knock sensors.

Inspect the coolant.

Follow the appropriate procedure based on the condition of the coolant.
