The 2005 Grand Am was a fifth generation model and the final year in the Grand Am line. Its key selling point was a powerful V-6 for a relatively inexpensive sticker price. These V-6 engines utilized a radiator system that circulated coolant or antifreeze throughout the engine to keep it running at the optimum temperature. A DIY mechanic can learn how to drain the antifreeze on a 2005 Grand Am with minimal effort. Draining the antifreeze is necessary if you'd like to flush the system and replace the coolant as a routine maintenance task.
Park the 2005 Grand Am on a level spot where you will have room to work safely on your car. Your driveway or garage is an ideal location for this chore. Set the parking brake and pop the hood latch. Allow the engine to cool for about 30 minutes.
Look under the hood and locate the radiator cap. It is on top of the radiator at the front of the engine. Place a rag over the cap and turn the cap counterclockwise. After about one-quarter of a turn, press down on the cap to remove.
Slide the drain pan under the car and position yourself underneath the radiator at the front of the 2005 Grand Am. Look for the plastic or brass radiator drain plug; it is on the bottom of the radiator on the driver's side. Place the drain pan directly under the plug.
Use the pliers to turn the drain plug counterclockwise. Pull the drain plug out of the radiator and allow the fluid inside to drain into the pan. Replace the drain plug when the fluid has stopped dripping from the radiator.
