If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
Radiator drain plug sizes vary from vehicle to vehicle. Some radiators have a drain plug and others have a petcock.
Not all radiators have petcocks. Simply disconnect the bottom hose to drain.

Search for a drain petcock along the lower edge of the radiator tanks. Loosen the valve with a pliers, but DO NOT OVERTIGHETEN IT. Not all radiators have one. If you can't find one, then you will have to remove the lower radiator hose which will drain most of the coolant from the engine block too.
