Smile 2000 Lesabre - Radiator Petcock & Eng Block Drain ??

Anyone know where the petcock / radiator drain is on a 2000 LeSabre ?? Also is there a engine block drain that will allow draining the block so you can get enought anti-freeze back in to provide proper mixture ???

The drain plug on the radiator should be located at the left hand side (drivers) bottom corner either on the front or back (most likely engine side).

The SII 3800 has two engine block drain plugs. One front and one back but I would seriously not mess with them. Difficult to access for routine radiator service and/or cooling system service/flushing.

How critical is it to change antifreeze? I never changed it in my 2000 Lesabre, and have not changed it in my wife's 95 Regal we bought new. The Regal is now 11 years old, 250000 miles and all I have replaced is a gas tank, tires, and brakes. (Still has original exhaust/muffler). The rad and coolant look fine.
