remove the thermostat and put back together then with upper hose disconnected from radiator put garden hose in with water on . then start the car u must have th lower radiator hosse disconnected as well. this will use the water pump to power flush the engine. make sure u dont over heat the car then add straight antifreeze when done. questions call my shop we 'll help u or perform service for u . thanks .
Thanks! My friend has been pulling his hair out!
