How do you fulsh the radiator system on a 1993 Chevrolet Corsica?

Answer 1

First drain the Rad of all the old fluid, refill it with water and simple green, should be about 1/3 simple green and 2/3, maybe 1/4 and 3/4....close enough. start the car and let it run cap off, it will get to normal operating temp, you may need to add just a little bit more. put the cap on and let it run for 10-15 minutes. then shut the car off and drain the solution. fill it back up with your antifreez and water and run it! 1/3 simple green and 2/3 water. (must of backspaced the water part)
