My anti freez is leaking really strongly throught the heating system. It leaks even into the car. and alot out side. How do I approach the heater. do I go in from the engine side or do I have to take out the whole dash board?

Yes, you will have to remove the dash. It is time consuming and a delicate job. Here are some links to see if your up to the task.

Wow. thanks. That helped alot. Its just this one guy came over and said you dont have to take off the dash board. I was like. What? cause I already did. So now this really helped me know I am going on a right track. thank you so much.

Any time!

And I have one more question. The problem in my car is that it leaks anti freeze in side the car where there is one of the throttles on the heating system. But when you look through the hood. and there is the foil. it just pours antifreeze through there on the left side when looking at the car from the front. I dont know what is part that I need to change. Anyone know?
