You mean flush the coolant system, right?

It's fairly simple to get done.

1)There is a draincock on the bottom passenger side of the radiator. It's just a cheap plastic thing that you can untwist with a pair of pliers. Let all the coolant drain out into a bin of some sort.

2)To flush it, put the draincock back in, and fill the system up with 100% water and start the engine.

3)Let the engine reach operating temperature so that the thermo will open and let the pure water go through the system.

4)After it gets up to a decent temperature and has been running for a couple minutes, turn off the car and drain the water.

5) Repeat steps 1-4 until water comes out clean (it will take a couple)

6) Put draincock back in and this time fill with 50/50 mix of coolant and water until system is full.

7) Make sure you bleed the system via the two bleed valves on top of the hose going to the radiator and the one right on the thermo housing when you refill each time!!!!

Hope this helps!

Not saying this to insult you. If you're new to working on your car, you should go out & buy a Chilton manual for your car. It will help you out alot.
