Flushing

Coolant must be 50% water and 50% coolant.

 

Important: Do not use a chemical flush.

Store used coolant in a properly labeled container. Do not pour used coolant down a drain. Ethylene glycol antifreeze is a very toxic chemical. Do not dispose of coolant into the sewer system or ground water. This is illegal and ecologically unsound. Various methods and equipment can be used to flush the cooling system. If special equipment is used, such as a back flusher, follow the manufacturer's instruction.
When the cooling system becomes contaminated, the cooling system should be flushed thoroughly to remove the contaminants before the engine is seriously damaged.

  1. Drain the cooling system.

  1. Remove the coolant recovery reservoir.

  1. Clean and flush the coolant recovery reservoir with clean, drinkable water.
  2. Install the coolant recovery reservoir.
  3. Follow the drain and fill procedure using only clean, drinkable water.
  4. Run the engine for 20 minutes.
  5. Stop the engine.
  6. Drain the cooling system.
  7. Repeat the procedure if necessary, until the fluid is nearly colorless.
  8. Fill the cooling system.

Other option is as follows.

1. Remove thermostat.

2. Remove lower radiator hose (one clamp is enough)

3. Flush engine with a water hose.

4 flush radiator with hose.

5 Remove and clean overflow.

Reinstall thermostat, lower hose and refill coolant. Check for leaks.

I still don't know how or where to drain the antifreeze. I can't find the plug or hose to do this. Can you get specific with my vehicle? 2002 buick regal ls V6 3.8 L
Expert:  Rmldaytona replied 7 years ago.

The drain plug is on the driver's side of the radiator. It is on the bottom and on the engine side.
