wait for the engine to cool
Remove the radiator cap ONLY when the engine is cold.
If it is clean, undamaged, and in good working condition.....NO. Since the radiator needs to be removed, to remove the engine, now is a good time to have it cleaned and checked.
* With the engine cold remove the radiator cap * Move a large container under to catch the coolant as you drain it * Drain the radiator by opening the drain plug at the bottom on the left side
Pour it into the expansion bottle not the radiator type cap on the engine, opening that will give you steam burns if the engine is hot.
The thermostat regulates coolant flow through the radiator by opening and closing based on the engine temperature. When the engine is cold, the thermostat remains closed to allow it to warm up quickly. As the engine heats up, the thermostat opens to allow coolant to flow through the radiator and dissipate the heat.
The radiator does not have a cap as most cars do. You add coolant to the reservoir bottle. The reservoir bottle may be under pressure when the engine is warm. Use caution when opening.

To flush a radiator, first make sure the engine is off and cool. Locate the radiator drain plug, usually at the bottom, and use a container to catch the old coolant. Pour radiator flush solution and water into the radiator, run the engine for a few minutes, then drain the radiator by opening the drain plug. Finally, refill the radiator with the recommended coolant and water mixture.

To remove the radiator on a 2003 Buick Century, first ensure the engine is cool and disconnect the negative battery cable. Drain the coolant by opening the radiator petcock and removing the lower radiator hose. Disconnect the upper radiator hose, remove any mounting brackets, and detach the transmission cooler lines if applicable. Finally, lift the radiator out of the engine bay, taking care not to damage surrounding components.
if i am not mistaken there is no "raditor cap" The cap that vents the radiator is on the overflow canistor. usually plastic, usually black. use the same safety precautions, getting burnt in not uncommon. do this when the engine is cold if possible. hope it helps. duboff
The fan should run when the engine reaches a set temperture. If it does not and the engine is overheating, check the thermal relay.
