well its bound to make a little mess but you should have a drain plug on the radiator at the bottom towards the engine side on one of the 2 tanks (sides of radiator ) unscrew drain plug and let drain into a pail or pan ( 2 gallon ) after it drains remove lower radiator hose. use a garden hose and fill radiator and let it flush for a little, hook lower radiator hose back, tighten drain plug and fill with a 50/50 mix new antifreeze,

Uncap the radiator, and unscrew the radiator drain plug. Normally, this drain plug is located on the inside bottom of the radiator, but models will vary. Once the drain plug is unscrewed, coolant will rush out into the drain pan. If there is not a drain plug, then disconnecting the lower radiator hose will be adequate.

hello. on the drivers side of radiator is a drain. here is a picture and the instructions for draining the coolant out.

Install a tube on the radiator drain. Place the end of the tube in the drain pan.

After the engine cools down, remove the radiator cap.

Completely open the radiator drain ****.

Allow the coolant to drain from the system until the flow stops.

Place a drain pan under the block drain hole plug.

Remove the drain hole plug from the engine block.

Allow the coolant to drain from the block until the flow stops. There may be more drainage from the radiator at this time.

Install the block drain hole plug.

Close the radiator drain ****.

Should be a drain **** at the bottom of the radiator that unscrews out. It looks like a wing nut has been welded to a bolt on the end of it. Another way to do this is just pull off the bottom hose.

There is drain plug on the drivers side of the radiator at the bottom, but the safest way is to just remove the lower radiator hose on the passenger side to drain the radiator. The drain plug is plastic and it may crack due to time and heat and you'll have to buy a replacement radiator drain plug, for this reason most newer radiator don't come with a drain plug and if you want one you'll have to install the drain plug kit. If your radiator doesn't have a drain plug then you have the newer radiators install already as the older radiators we still being installed until they were all gone and the new ones were installed.
Thank you for using Fixya.

It's located on the drivers side of the radiator opposite of the lower radiator hose. Note: you may be better off disconnecting the lower radiator hose, it's common for the drain plug to break or the O-rings to split causing more work to drain the radiator. That's why most tech's will drain the radiator from the lower radiator hose, less chance of breaking the radiator drain plug and most new cars now don't come with a drain plug to the radiator.

Great news for you, the best way to drain the radiator is to remove the lower radiator hose. The bad news is that OEM radiator came with no drain plug and you can have one put in after you remove the radiator to drill a hole and tap in a $6.00 radiator drain plug for NAPA auto parts. Good luck and hope this helps. this was a way for GM to save money by one less parts to have make, since most auto mechanic just remove the lower radiator hose to drain the radiator. Good luck and hope this helps. If your luck and your Astor does have one, you can find the drain plug on the lower drivers side of the radiator, engine side.
