If the engine is cold the fastest way is just to put a big drain pan under the bottom radiator hose and remove it. If the engine is hot there is a petcock on the bottom of the radiator it will be on the side under the hood, either side usually opposite the lower radiator hose.

    • Introduce a flow of water from a garden hose into a created opening, either the hose or other end.


    • Keep doing this until water is clear coming out opposite end.

How do I get to the radiator drain plug? 2003 Astro Van


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.
