What is coolant and how can it be checked? Coolant is a fluid that transfers heat and helps regulate the temperature of the engine block and parts. No matter whether you drive a new or used vehicle, engine coolant is important. The engine coolant also contains an additive that ensures it won’t freeze 32 degrees Fahrenheit and that it won’t overheat above 212 degrees Fahrenheit. Learn more about how to check coolant levels, when to change it, and more with our service team at BMW of Mamaroneck.
Instead of opening the radiator cap, you can check the markings on the side of the reservoir. If the fluid reaches the “full” marking line, you’re good to go. If it doesn’t, you’ll want to remove the radiator cap and add either the coolant, or a 50/50 mix of coolant/water. Be sure to read the bottle to see if it’s pre-mixed. While checking the levels, inspect the hoses connected to the radiator for any damage or 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.
Coolant is thinner than oil but thicker than water. If the fluid looks sludgy, be sure to schedule service ASAP. This could mean there’s a good change that your model has an internal gasket leak. Driving is possible, but a leaking gasket will drain quickly, putting your engine at risk of overheating.
Over time, coolant levels will deplete. It’s a good idea to check on the cooling system every three to six months. The liquid can be a blue, yellow, green, or red. If it’s brownish or colorless, flush the system and replace the fluid immediately.
