A few early models had a drain valve on the radiator. All the newer models are done the old fashioned way if you do it yourself. Pull the lower rad hose. Most shops have an inline change system that is clean and fast. Dexcool is the only coolant recommended for your truck and a flush out is seldom needed as the Dex stays very clean.

Where is the plug for the radiator on a 2004 Oldsmobile alero?
There is no plug. GM in their infinite wisdom decided we don't need to change our coolant in the rad. Therefore to do this you must remove the lower rad hose to drain the coolant. Nice move GM. And you wonder why no one wants your cars anymore. All for the cost of a simple drain spigot.

On the GM 4.8 engine, the block drain plug for coolant is typically located on the driver's side of the engine block, towards the rear. It is a small threaded plug that can be removed to drain coolant from the engine block. Make sure to allow the engine to cool down before attempting to remove the plug to avoid burns from hot coolant. Always check the vehicle's service manual for the exact location and specifications.
