The radiator has a drain on the lower right. Sometimes it isn;t easy to get to so I take the lower rad hose off. The trans pan has to be removed to drain the trans.
On the driver's side lower rear of the radiator is a PLASTIC 'drain plug about 1 1/2 inch in diameter. After the car is cool, first open the radiator cap ( you need to twist CCW and push down hard at the same time), Then CAREFULLY with a pair of duck bill pliers or the like, unscrew the drain plug..BE CAREFUL!!!! if you break this plug it is a major pain in the a.. to replace it. Drain the coolant into a proper container and don't spill it as animals and kids love the sweet taste of antifreeze right up till it kills them. When the system is completely drained ( including coolant used to cool the trans),replace the plastic drain plug CAREFULLY
Near the waterpunp (passenger side of engine you will see a "fitting " with a nut and another bolt in the nut.... this is a vent device ...lossen the bolt to let air escape when you add the new coolant. There is also another "vent" on the driver side hose from the radiator.. do the same thing here. The object of the procedure is to refill the system WITHOUT any air pockets. Once this is achieved , make sure the two "vents" are closed. Run the engine with the radiator cap off long enough to insure the coolant level stays right to the top of the radiator fill pipe.replace the cap and insure that the reservoir tank is filled to the proper level. Take a ride then let the car cool down again then remove the cap again to make sure the coolant is still up in the fill neck. Please dispose of the anti freeze properly...nasty stuff!!! Most AutoZones will recycle it for free for you...good luck RONCO
another 1992 buick century radiator
On a 1992 Buick Century, the oil filter is located between the radiator and the lower front of the engine. The radiator is situated in slightly in front of the filter.

Look in the housing located at the engine end of the upper radiator hose
Look in the removable housing at the engine end of the upper radiator hose
Is there a drain plug on a 2005 Buick century
The coolant temp sensor on a 97 Buick Century is on the side of the radiator. It is just below the radiator cap.
Should be in a removable housing at the engine end of the upper radiator hose
