Many people wonder if they can use water as a substitute for coolant, but it’s essential to understand the differences between water and coolant and the potential consequences of using water in a coolant system.
What is Coolant and How Does it Work?
Coolant is a mixture of water and antifreeze, typically ethylene glycol or propylene glycol, which helps to lower the freezing point and raise the boiling point of the liquid. This allows the coolant to flow smoothly through the system, even in extreme temperatures. The coolant absorbs heat from the engine and transfers it to the radiator, where it is dissipated. The antifreeze also helps to protect the system from corrosion and damage caused by freezing temperatures.
In contrast, water has a higher freezing point and a lower boiling point than coolant, which makes it less effective at regulating temperature. Water also lacks the corrosion-inhibiting properties of antifreeze, which can lead to damage to the system over time. While water may seem like a convenient and inexpensive substitute for coolant, it’s not a recommended solution.
Potential Risks of Using Water as a Coolant
Using water as a coolant can lead to several problems, including:
