How to Check Coolant Levels

Coolant Car Check


If you’re new to car ownership or you’re looking to take on DIY car care in your own Omaha garage, you may ask, “What is coolant?” Coolant is a fluid that transfers heat and maintains a stable temperature inside your engine. Whether you drive a new or used model, coolant is critical for safe Lincoln travels. Engine coolant is formulated so that it won’t freeze below 32 degrees Fahrenheit, and it won’t overheat above 212 degrees Fahrenheit. Now that you can answer the question, “What is coolant?” you’re likely wondering how to maintain it! Read on below with our service team to learn how to check your coolant levels and when to change it.

 

 

What to Look for When Checking Coolant Levels

Luckily, if you’re new to at-home maintenance, learning how to check coolant levels is a great introduction! Why? Because you don’t even have to open the radiator cap to check the fluid level. Instead, you can check the markings on the side of the reservoir to see if the liquid reaches the “full” indicator. If not, remove the radiator cap and add the coolant or a 50/50 mix of coolant/water. Be sure to check your coolant to see if it’s pre-mixed. You can also take this chance to inspect the hoses connected to the radiator to see if there are any leaks or damage.

Note: If you do need to add more coolant to the system, be sure to let the engine cool down. Don’t even attempt to open the radiator cap until your vehicle is cooled.

When to See a Service Technician

Coolant should be thinner than oil, but thicker than water. If you notice the liquid has become sludge-like, schedule service with us immediately. This is often a sign that your vehicle has an internal gasket leak. Driving under these conditions is possible, but it will quickly drain your coolant. Once the coolant is gone, your engine is at great risk of overheating.

When to Change Coolant

Naturally, coolant levels deplete over time, so you’ll want to check your coolant system every three to six months. In most cases, the liquid is blue, green, yellow, or red. If the color of the fluid is brown or clear, you’ll need to flush the system and replace the fluid.
