Just found it. Have been looking myself for the last 10 min. If you face the car from the front the plug will be on the right side of the radiator tank facing you. It is a little white/yellow plug that you can use a allen wrench to loosen.
Look at the lower or rear of radiator
the rad drain plug is located on the drivers side behind the front bumper
No
To drain the radiator on a 2001 GMC Sonoma, first ensure the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Place a drain pan under the radiator, open the drain plug, and allow the coolant to fully drain out. After draining, close the plug securely, and refill the radiator with fresh coolant. Be sure to dispose of the old coolant properly, as it is toxic.
under the radiator, driver side.
Either at the bottom or the rear of the radiator
Look on bottom or rear of radiator
It may or may not have a drain plug for the radiator. Look at the bottom of the radiator usually on the passenger side of the car. It doesn't really look like an actual plug. It is more like a plastick wing nut, just unscrew it and it should drain. Some radiators don't have drain plugs at all. If it doesn't just take off the lower radiator hose from either the radiator or the engine block and do it that way i think the sunfire drain is on the driverside of radiator facing forward. it should be a 1/4 inch hole in center. you have to turn and pull to drain. be careful not to damage plug or radiator.
If it is not on the bottom of the radiator, then just remove the lower radiator hose to drain the system.
On the bottom right of the radiator there should be a small square piece that is the plug. You twist it out and the coolant will come out.
The radiator drain plug should be close to the bottom of the radiator facing the engine. It could be a wing nut, or could be the type that is turned by a ratchet and extension.
The Chevrolet Malibu radiator drain plug can be found on the right side of the radiator. The drain plug will be at the bottom of the radiator.
