Check the hoses and around the clamps to see if it is possibly leaking from there. Radiator sealer works fine on small leaks.If all else looks good you are on the way to have your rad repaired.(also check around the water pump,when they go they leak bad!!) if the sealant doesn't work and you can see where the leak is coming from, then remove the radiator, if necessary, drain it. you then need to clean the area where the leak is with a wire brush and alcohol. then get a small plumbers torch and some resin core solder and seal the leak. if that doesn't work you may have to have it recored or buy another one.

Why does your 97 Dodge Ram lose antifreeze?

Vehicles lose antifreeze because they loose coolant. You have a 13 year old vehicle. Your radiator and heater hoses may be leaking and should have been changed from original equipment by now. If they have not, change them before you are on the highway and they break. After that is done, and if you are still losing antifreeze, we will look for the leak. When you start up, does white smoke come out the tail pipe? If so, you will need to check your head gasket. You will need to look around your water pump and radiator for leaks.

What to do when water freezes in automobile?

If you mean the water in your radiator, don't drive your vehicle until it thaws or your engine will overheat because no coolant will be flowing through it.

(maybe slightly more antifreeze in cold winter weather) Water in the radiator won't freeze with antifreeze mixed with it.
