What Happens When You’re Low on Coolant?

When your car is low on coolant, it can lead to several problems. First, your engine may overheat because coolant helps regulate its temperature. Additionally, low coolant levels can cause damage to engine components due to increased friction and heat.

Without enough coolant, your car’s heater may also stop working properly, leading to discomfort during colder weather. Lastly, low coolant levels can indicate underlying issues with your car’s cooling system that need to be addressed promptly to prevent further damage.

Signs of Coolant System Issues

Signs of coolant system issues in your car include.

  • Engine overheating: If your engine temperature gauge shows high readings or you notice steam coming from under the hood, it could indicate coolant system problems.
  • Low coolant level: Regularly check the coolant reservoir for low levels, which could suggest leaks or other issues.
  • Coolant leaks: Look for puddles or stains under your car, particularly beneath the radiator or engine, indicating leaks in the coolant system.
  • Sweet smell: A sweet, syrupy smell inside or outside your car might indicate a coolant leak.
  • Heater issues: If your heater isn’t producing enough heat or doesn’t work at all, it could be due to coolant system problems.
  • Engine misfires or stalling: Coolant leaks into the engine can affect its performance, leading to rough idling, misfires, or stalling.

If you notice any of these signs, it’s essential to have your coolant system inspected and repaired by a qualified mechanic to prevent further damage to your vehicle.

Coolant vs. Antifreeze

Coolant and antifreeze are often used interchangeably, but they serve slightly different purposes.

Coolant: Coolant is a mixture of water and antifreeze. It serves to regulate the temperature of the engine by absorbing heat and transferring it away from the engine components. Coolant also contains corrosion inhibitors to protect the engine’s metal parts from rust and corrosion.

Antifreeze: Antifreeze is a concentrated liquid that is mixed with water to create coolant. Its primary function is to lower the freezing point of the coolant, preventing it from freezing in cold temperatures. Additionally, antifreeze raises the boiling point of the coolant, allowing it to effectively cool the engine even at high temperatures.


In summary, coolant is the mixture of water and antifreeze that circulates through the engine to regulate temperature and prevent corrosion, while antifreeze is the concentrated liquid additive that lowers the freezing point of the coolant.
