What is Coolant?

Coolant Car Check

What is coolant? It’s one of the most important fluids in your car—it helps regulate the temperature of the engine block and parts. No matter the age of your car, engine coolant is required to keep it running on New London streets without issue. It contains an additive that prevents it from freezing below 32 degrees and another that prevents it from heating above 212 degrees. The service center at Westbrook Honda can help you answer, “What is coolant?” and show you how to check coolant levels. 

How to Check Coolant Levels

Since opening your vehicle’s radiator can be dangerous, the coolant reservoir is clear and has safe and convenient markings on its side so you can see how much coolant it contains. Anytime the coolant level is below the “full” marking, add some more. First, make sure the engine has cooled from your last drive before you remove the reservoir lid! Then, check the coolant bottle to see if it’s premixed with water or if it’s a concentrate that needs water added to it. Follow the instructions on the bottle from there. After you add the coolant take a look to make sure the hoses are properly connected to the radiator and aren’t leaking or damaged.

When to See a Service Technician 

If you noticed a sludgy appearance to your coolant, schedule service as soon as possible. This is a sign of an internal gasket leak. You’ll be able to drive in Branford, but you’ll quickly lose coolant, which puts your engine at risk of overheating. 

When to Change Coolant

It’s a good idea to check your coolant levels every three to six months. The liquid consistency should be thicker than water but not as thick as oil. The color should be blue, green, yellow, or red. If it’s brownish or colorless, you’ll need to flush the system and replace the fluid. When you bring your car to Westbrook Honda for regular maintenance, we’ll check your coolant for you.
