Where could antifreeze go if i don't see a leak in 2003 windstar?

Answer 1

Its likely that you have a blown head gasket which is an expensive repair. I had the same problem with a 93 Taurus. It was leaking so badly that I could only go 20 miles on the freeway without having to put more water in.

However, I found a simple repair that cost me $18. In Canada, we have an auto part store called Lordco. I went there and bought a product called Irontight. If you don't have a Lordco near you, you will have to find out where they sell this product.

There are 2 types of this product. One you just dump into the water and keep driving. This stuff didn't work well for me. There is another type that requires you to remove the anti freeze and then put in the stuff. It says on the bottle that it forms a ceramic coating. They say to run it through your cooling system for 3 days and then flush out your cooling system. I left it in for a week. 3 years and 70,000 kilometers later, I am still driving this car and it doesn't leak water out of the head gasket. Not bad for $18 that would have cost over $1200 at a shop.
