How to Check Coolant Levels

Coolant Levels

You may be wondering, “What is coolant?” Coolant is a fluid that transfers heat and controls the temperature of the engine block and parts. Whether you are driving a new or used INFINITI vehicle, engine coolant is essential. Coolant contains additives to ensure it remains below 32 degrees F, but also doesn’t evaporate above 212 degrees F. Learn more about how to check coolant levels and when to change it with the experts at the Flemington INFINITI service center!

What to Look for When Inspecting the Coolant

You don’t need to open the radiator cap to check the level. Take a look at the markings on the side of the reservoir. If the liquid reaches the “full” marking line, everything is good to go. If not, take off the cap and add the coolant or about a 50/50 mix of coolant/water. Check the bottle you have and see if it is premixed. Also, check the hoses connected to the radiator for any leaks or damage.

Note: If you add more liquid to the cooling system, make sure the engine has cooled. Also, do not try to open the radiator cap while the engine is hot.

Is a Service Technician Needed?

Coolant is thinner than oil but thicker than water. When inspecting the coolant, does it have a sludgy appearance? If it does, schedule a service appointment as soon as possible. There is a chance that your car has an internal gasket leak. While driving is possible, a leaking gasket will drain the coolant quickly, causing the engine to overheat and potentially lead to damage.

When to Change Coolant

Coolant levels deplete over time, so best to check the cooling system every three to six months. Usually, the liquid is blue, green, yellow, or red. If it’s brownish or colorless, it’s time to flush the system and replace the fluid. Contact our service center if you have any questions about changing the coolant.
