The radiator drain is on the drivers side all most to the bottom of the tank. Remove the bottom shield, then gently move the lines that may be blocking access to the drain plug. The plug has 2 wings, Just loosen it the plug does not have to come all the way out. You may have to put a small screwdriver in the drain hole (on the bottom of the side tank of the radiator to get the radiator to drain) Also remove the cap on the surge tank.Hope this helps

Something is draining my battery on my 1998 Cadillac DeVille


I suspect parasitic draw. All vehicles draw some power from the batteries when the car is shut off. Certain accessories such as clocks, radios remote door openers and alarms always need power. The normal power used is called parasitic draw.

It is always a very low draw so it doesn't run the battery down. If you install accessories like shortwave radios or plug things like inverters and portable refrigerators into the accessory socket and operate them too long without the engine running you can drain your batteries to the point where the engine won't start. If there is an electrical short in the vehicle or a malfunctioning accessory it could be drawing much more than its normal load causing a drain on the batteries. If you leave your door open and the inside lights stay on all night you could drain the battery down till the car won't start.

Here's also a good resource for your car specifically on narrowing down the cause of the drain.

Where is the radiator drain plug on a 2000 cadillac deville


Drain plug should be on the drivers side of the radiator, lower back (towards the engine) When placing the drain plug on place use some oil on the O ring to ensure a good seal when tightening it back in place. Good luck and keep me posted.
