What is Coolant and What Does it Do?

Updated: Aug 23

The automotive world is overwhelming for most. It's oftentimes seen as a different universe altogether. The moving parts, the tiny pieces, and all of those components help a vehicle function. There are 9 different systems in a vehicle; the engine, fuel, transmission, electrical, cooling, and lubrication, and the chassis, which includes suspension, braking, wheels and tires, and the body. Today we are focusing on the cooling system, or more specifically, the coolant. Let's dive in!


What is the primary function of coolant?

Like oil, the coolant's job is to lubricate the components of the vehicle and transfer the excess heat away from the engine. It also helps prevent engine damage from freezing or boiling and prevents damage to the metals, rubber, and plastic parts inside the engine.


What is the most important part of the cooling system?

As stated above, coolant is in charge of siphoning heat from the engine, moving it out of the vehicle, and preventing the engine's metal components from rusting. Without coolant, the entire cooling system wouldn't function at all. This is why it's so important to service the cooling system every 30,000 to 60,000 miles, and checked at every oil change according to your vehicle's recommended oil and filter intervals.


What causes the coolant warning light to come on?


Dashboard Warning Coolant Level Low

Usually, when your coolant light comes on it indicates low coolant levels. Low levels could be caused by something as simple as a leak. If this happens, your vehicle's cooling system needs to be pressure tested. You can usually detect leaks easily, but sometimes they can be hidden in the lines, so if you notice your coolant light come on, get your vehicle to your preferred automotive shop so they can help prevent any further damage.


Why does my coolant keep leaking?


Coolant Leak

I am sure you've learned, having a coolant leak is BAD. The cooling system is nothing without coolant. So, a leak is more serious than most realize and should be corrected ASAP. Leaks could be caused by a blown radiator hose, a bad hose clamp, a warped head gasket, or something that got kicked up and puncturing the radiator. Your mechanic will detect this problem and repair it.


When your vehicle is brought in for service at Quality Automotive our educated technicians will thoroughly inspect the cooling system and the coolant, making sure the quality and levels are sufficient. We can help keep your cooling system running smoothly.
