How to Check Coolant Levels

First and foremost, you should know the answer to: “What is coolant?” Coolant is a fluid that transfers heat and regulates the temperature of the engine block and parts, keeping your vehicle running smoothly and safely. In addition to knowing, “What is coolant?”, we believe Belton drivers should also know more about the following topics:

How To Check Coolant Levels: What to Look for 

You don’t have to open the radiator cap or a coolant level sensor 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.

Now, do you want to know what to do when coolant levels are low? It’s simple! Remove the radiator cap and add the coolant or a 50/50 mix of coolant/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, be sure the engine has cooled. Also, don’t attempt to open the radiator cap while the engine is 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 drain the coolant quickly. This means the engine is at risk of overheating and being severely damaged. 

When to Change Coolant

Coolant levels deplete over time, so it’s a good idea to check on the cooling system every three to six months to see if your coolant level is low. Usually, the liquid is blue, green, yellow, or red. If it’s brownish or even colorless, flush the system and replace the fluid.
