How to Check Coolant Levels

Coolant Levels Under Hood

Wondering how to check coolant? You may have a couple of questions before you perform this automotive service. One of the first questions you may have is, “What is coolant?” Coolant is a fluid that transfers heat and regulates the temperature of the engine block and parts. Coolant is an essential component of all vehicles, whether you drive a brand new car or you have just purchased a used model. It is able to regulate the temperature of your engine thanks to additives to ensure it stays below 32 degrees F. Coolant will also not evaporate above 212 degrees F. Don Franklin Auto has the details on how to check coolant levels and when coolant should be changed.

What Should I Keep an Eye Out For?

Opening up the radiator cap is not necessary for you to check the level. All you have to do is look at the markings on the side of the reservoir. If the coolant level is at the “full” marking line, there is nothing else that you need to do. If it is not at the proper level, take the radiator cap off and add the coolant or a 50/50 mix of coolant/water. Check the bottle to see if the coolant you bought is premixed. This is a good time to also take a look at the hoses connected to the radiator to see if there is any damage or if they are leaking.

Note:Be sure the engine has cooled before you add more coolant. Also, remember to wait until the engine is cool before you try and open the radiator cap.

When Does My Vehicle Require Service?

Coolant is thinner than oil but thicker than water. If you see that the coolant looks a little sludgy, you will want to make an appointment at the Don Franklin Auto service center as soon as you can. This could be a sign of an internal gasket leak. You can still drive with this issue, but a leaking gasket will drain the coolant quickly. This could lead to engine damage and overheating.

When Should I Change the Coolant in My Car?

Checking the coolant level every three to six months is recommended because coolant levels deplete over time. Usually, the liquid is blue, green, yellow, or red. If it’s brownish or even colorless, it is time to flush the system and replace the fluid.
