How to Check Coolant Levels

Maybe you’re wondering, “What is coolant?” South Houston Nissan is happy to help. Coolant is a fluid that transfers heat and regulates the engine block’s temperature in your Nissan vehicle. Whether you drive a new Nissan or a used car from another brand, engine coolant is an essential fluid for your vehicle’s health and performance. Engine coolant includes an additive that keeps it from freezing when the temperature is below 32 degrees Fahrenheit and protects it from overheating above 212 degrees Fahrenheit. Read on to learn more about how to check coolant levels and when you should change it! 

 

 

What to Look for When Checking Coolant Levels

Did you know that you don’t have to open the radiator cap to check the coolant level? Instead, you can check the markings on the side of the reservoir. If the liquid is at the “full” marking line, you’re fine. If it’s lower, remove the radiator cap and add the coolant or a 50/50 mix of coolant/water. Make sure that you read the container to see if it’s premixed. It’s also a good idea to inspect the hoses connected to the radiator for any damage or leaks. 

Note: If you’re adding more liquid to the cooling system, always ensure the engine has thoroughly cooled first. For your safety, don’t attempt to open the radiator cap if the engine is hot, otherwise hot vapors may erupt from the radiator.

When to Bring Your Vehicle to Our Service Center

Engine coolant is thinner than oil but thicker than water. If you notice that the liquid looks a bit sludgy, schedule service immediately. There’s a good chance your vehicle has an internal gasket leak. You can still drive your car around Pearland, but a leaking gasket will drain the coolant quickly, and that will put your engine at risk of overheating and becoming significantly damaged. 

When to Change Coolant

Coolant levels go down over time, so it’s a good idea to check on your cooling system every three to six months. Usually, the fluid is bluish, green, yellow, or red. If it looks brown or even colorless, flush the system and replace the coolant before driving around Pasadena.
