* Freezing: Water freezes at 32°F (0°C). If it freezes, it expands and can crack the radiator, engine block, or hoses.
* Corrosion: Water lacks the corrosion inhibitors found in antifreeze, leading to rust and scale buildup inside the cooling system, damaging components.
* Boiling: Water boils at a lower temperature than the proper coolant mixture, leading to overheating and potential engine damage.
Always use a mixture of coolant and distilled water as recommended by your Dodge Ram 1500's owner's manual. The ratio is usually 50/50, but check your manual to be sure.
