Don't get me wrong BUT...... That would be leaving yourself wide open for a BIG repair ticket. I don't know if you are into the "Do it Yourself" thing but there are alot of service jobs you can do yourself and learn about your car at the same time.
I would service the cooling system if it has never been done.
