Where is the radiator drain on an 1992 Oldsmobile Delta 88?

The radiator drain petcock on a 1992 Oldsmobile Delta 88 is typically located at the bottom of the radiator, on the driver's side. However, it's *not always* a readily visible, easily accessible petcock like on some older vehicles. It might be a small valve, a plug, or even integrated into the radiator's lower hose connection.

To find it, you'll need to:

1. Locate the radiator: It's the large metal unit at the front of the engine compartment.

2. Look at the bottom of the radiator on the driver's side: Carefully inspect the lower portion for a small valve, plug, or a slightly different fitting than the rest of the radiator. You might need a flashlight.

3. Consult a repair manual: A repair manual specific to your 1992 Oldsmobile Delta 88 will show the exact location and type of drain. This is the most reliable method.

Important Note: Be prepared for coolant to be hot if the engine has recently been running. Allow it to cool down completely before attempting to drain the radiator. Also, have a suitable drain pan ready to catch the coolant.
