Hello, I have a 2003 Dodge Grand Caravan with 55,000 miles. I bought it used over 3 years ago with 49,000. Something that has been a consistent issue over my time with it is the antifreeze seemingly evaporates. I've had the cooling system pressure tested and everything checks fine but every few months I have to add a gallon or more of antifreeze, It's not leaking anywhere that can be found. I'm thinking or most likely hoping it could be a bad radiator cap and that simple. Could that be it or any ideas, things to check or have checked?

You're definitely losing it somewhere. You may not have pressure tested it sufficiently or it could be burning it through a blown head gasket or intake gasket leak.

Jake - listen to Hammer Time. Pressure check the system - whatever works - use powder (non flammable) or whatever and find the leak.

Hey - if hot where you are and using pure EG antifreeze that alone is a horrible product for heat exchange unlike the crap they say on the container. 50/50 is the standard. That equals negative 34F. Got the T-shirt - it will be slush if colder than that and shrink, not the damaging expansion,
