How To Check Coolant Level

Every internal combustion engine needs engine coolant to keep the moving parts within their operational temperature. Engine parts move, creating friction and heat on Salado jaunts. If the heat becomes too much, you run the risk of engine damage. Coolant is a fluid that transfers heat and regulates the temperature of the engine block and many of the moving parts. Whether you drive a new or used car, engine coolant is crucial to the operation of your car, truck, or SUV. 

Read on to learn more about how to check coolant levels and when to change it with our guide from Don Ringler Chevrolet. We’ll answer the question “What is coolant?” and get to the bottom of more details.

What Is Coolant?

Engine coolant contains an additive, called ethylene glycol, to keep the substance from freezing below 32 degrees Fahrenheit and to prevent boiling above 212 degrees Fahrenheit on your Killeen drives.

What to Look for When Learning How to Check Coolant Levels 

We’ve answered, “What is coolant?” Moving on, you don’t have to open the coolant reservoir to check the coolant 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 the coolant doesn’t measure up, remove the cap and add the coolant or a 50/50 mix of coolant/water. If your engine coolant is premixed, you don’t have to mix in water. Now is a good time to check the hoses on the side of the reservoir to check for leaks.

Note: If you’re adding more liquid to the cooling system, be sure the engine has cooled. Also, don’t attempt to open the radiator cap while the engine is hot. The fluid might sploosh out and scald you.

When to See a Service Technician 

Coolant is thinner than oil but thicker than water. If you notice a sludge or thickness to the engine coolant, schedule service ASAP. There’s a good chance your car has an internal gasket leak. You can drive your vehicle for a little bit, but a leaking gasket will drain the coolant quickly. An overly hot engine is at risk of severe damage. 

When to Change Engine Coolant

Coolant levels naturally deplete over time as you drive, so it’s a good idea to check on the cooling system every three to six months. Usually, the liquid is blue, green, yellow, pink, or red. If it’s brownish or even colorless, flush the system and replace the fluid because it might not be effective anymore.
