I was losing anti-freeze on my 03', and I could not figure out where it was going. I happened to notice that the side of the radiator was stained with burned off anti-freeze. After checking the radiator cap, I noticed that anti-freeze was coming out of the overflow hose. The hose was very lose and when the engine was hot it was spitting anti-freeze. I had a small fuel line screw clamp that I installed on around the line and this stopped the flow! I am sure that after 6 years the hose was swelling at the connection. I thought about cutting out that section, but realized that this would not really solve the problem, but the clamp would.
