How to Locate the Radiator Drain on 98 Buick LeSabre

by Nathan McGinty

The radiator drain on a 1998 Buick LeSabre allows you to empty the contents of the radiator for flushing and refilling. To keep the LeSabre's engine at the optimum operating temperature, a pump circulates a mixture of radiator coolant and water through the engine, which absorbs the heat from combustion. The fluid then flows through the radiator, where it dissipates this heat out into the surrounding air. If you want to drain your car's radiator, the first thing you'll have to do is locate the radiator drain on your 98 Buick LeSabre.

Park your 98 Buick LeSabre in a location that will allow you to work comfortably around the front of the car. The driveway is a perfect location for this. Shift the LeSabre into park and set the parking brake. Turn off the motor. Remove the keys from the ignition.

Open the hood and prop it in the open position. Allow the engine to cool for at least 30 minutes. Use the wrench to disconnect the black (negative) battery cable from the battery terminal.

Place a block of wood underneath the rear tires of the LeSabre.

Insert the jack underneath the front jack point. On the 1998 Buick LeSabre, this is indicated by a small "X" on the underside just behind the front wheels. Jack the car up enough for you to comfortably work underneath it.

Position yourself underneath the engine. The radiator drain on the 1998 Buick LeSabre is located at the bottom of the radiator, towards the driver's side of the vehicle. Use the flashlight if necessary. You should be able to see the grips on the plug sticking out of the radiator. The plug may be brass or plastic.
