Why do I continually have to put coolant/water in my radiator?

Here is what you do first thing in the morning before you even start the van fill it with water and tighten the cap and drive it to auto zone go inside and ask one of the guys to please help you out and if they can pressure test your cooling system that you have a leak and cant locate it,and they will check it for ya for free. Mystery solved.,,,,,,,,,,

First of all, your AC probably just needs a charge. Your coolant could be leaking from the rear heater or inside the engine through a bad head gasket. If you suspect a bad gasket, go to the auto parts store and get the leak sealer. I have used that with several cars and it works. Always buy the best stuff and it will cost you around $30.00. Good luck!

If you HAVE to keep adding coolant, you have a leak. Denying it is futile, it's the ONLY place coolant will go.

The leak can be external and evaporating, it could be internal, block or head gasket, or it could be the radiator cap.

The ONLY thing you need to know, have to add coolant, have a leak.

Coolant and AC are two different systems.

sounds like you might have a head gasket leaking, if its the head gasket then it can be going into the oil or if its going out the exhaust you will see white smoke coming out when it is running
