Why Is Coolant Important?
More Than Just Antifreeze
Many people are familiar with antifreeze, but they may not know exactly what coolant does or why it’s important. In most vehicles, coolant is a mixture of antifreeze and water that helps regulate engine temperature year-round.
If you've ever wondered why coolant is important, the answer is simple. It helps protect your engine from extreme temperatures. During the winter, it helps stop your engine from freezing. During the summer, it helps keep your engine cool to prevent overheating.
What Does Coolant Do?
Your engine creates a lot of heat while it's running. Coolant helps absorb that heat and move it away from the engine. It then releases that heat through the radiator before circulating back through the cooling system.
Without coolant, your engine can quickly become too hot or too cold. Coolant works together with the water pump, radiator, thermostat, and cooling fan to help keep your engine at the right temperature. Modern coolant also contains additives that help protect the cooling system from rust, corrosion, and premature wear.
Why Does Coolant Matter in the Summer?
Coolant plays an important role during the summer months. As outside temperatures rise, your cooling system has to work harder to keep your engine at the proper temperature.
Road trips, stop-and-go traffic, hot weather, and running your car’s A/C can all put additional demands on the cooling system. Without enough coolant, it can become much harder for your engine to stay cool during the hottest days of the year.
What Happens When Coolant Levels Get Low?
Low coolant levels can make it harder for your cooling system to regulate engine temperature. One thing many drivers don't realize is that coolant is part of a closed system. If the coolant level is low, there is usually a reason.
At Mad Hatter Auto Repair, we commonly find coolant leaks coming from hoses, radiators, water pumps, thermostats, or other cooling system components. When there isn’t enough coolant moving through the system, your engine may start running hotter than normal. If left unchecked, a small leak can lead to overheating and more expensive repairs.
"A lot of drivers assume coolant naturally gets used up over time. While small losses can occur, a noticeable drop in coolant level often points to a leak or another cooling system issue that should be inspected. Finding the cause early can help prevent an overheating breakdown later."
