Many Rosenberg drivers are wondering, “What is coolant?” Engine coolant is a fluid that transfers heat and regulates the temperature of the engine block and other parts. Whether you drive a new or used car, engine coolant is crucial. Engine coolant contains an additive that ensures that it won’t freeze below 32 degrees Fahrenheit and that it won’t overheat above 212 degrees Fahrenheit. Read on to learn more about how to check coolant levels and when to change yours.
What is Coolant?
Many drivers overlook the importance of coolant. However, knowing what coolant is can help you appreciate its role in your vehicle’s cooling system. Coolant, commonly known as antifreeze, is a fluid that circulates through a car’s engine cooling system to help regulate its temperature and prevent overheating. It absorbs heat from the engine and transfers it to the radiator, where the heat is dissipated. The cooled fluid is then returned to the engine to repeat the cycle.
What to Look for When Checking Engine Coolant Levels
As a driver, it’s important to know how to check coolant levels. You don’t have to open the radiator cap to check the level. Instead, check the markings on the side of the reservoir. If the liquid reaches the “full” marking line, you’re good to go. If it doesn’t, remove the radiator cap and add coolant or a 50/50 mix of coolant and water. Read the bottle to see if it’s premixed. It’s also a good idea to inspect the hoses connected to the radiator for any leaks or damage.
Note: If you’re adding more liquid to the cooling system, ensure the engine has cooled first. Additionally, avoid attempting to open the radiator cap while the engine is still hot.
When to See a Service Technician
Coolant is thinner than oil but thicker than water. If you notice a sludgy appearance to the liquid, schedule service ASAP. There’s a good chance your car has an internal gasket leak. Driving is possible, but a leaking gasket will cause the coolant to drain quickly. This means the engine is at risk of overheating and potentially suffering severe damage.
When to Change Coolant
Coolant levels deplete over time, so it’s a good idea to check up on the cooling system every three to six months. Usually, the liquid is blue, green, yellow, or red. If it’s brownish or even colorless, flush the system and replace the fluid.
