3.   Locate the coolant reservoir

Once you're ready to check the coolant level and ensure it's flowing, you must pop up the hood and look for the coolant reservoir. Your vehicle owner manual can help you locate all the different components. Some experts even recommend looking at YouTube videos that could help you identify the location of the Corvair yourself by checking for vehicles similar to yours.

Usually, the coolant reservoir is a transparent reservoir with a fluid inside it. This fluid is usually pink unless it is very old and started collecting a lot of debris and containment, which might change its current fresh color.

4.   Check the coolant level

Once you Locate the reservoir, you need to observe it and look for the minimum and maximum mark to help yourself identify the current coolant level. Usually, the coolant level should fall between the minimum and maximum mark, and if it's below the minimum value, you have to top it off immediately.

After starting the engine, come back to the reservoir and see whether the coolant is moving or transported throughout the pathways. A quick visual inspection should be sufficient to help you identify any behaviors of your current reservoir.

Leaking Antifreeze Coolant

7.   Feel the radiator hoses

As the coolants start running around the engine, you'll feel that the radiator hoses should have different temperatures. When the engine is very hot, and as the coolant starts to observe the temperature, the reservoir hoses should get warmer and warmer as the coolant continues to run.

8.   Check the radiator fan

Once you confirm that the radiator hoses are getting warm, the next step is to look at the radiator fan. Typically, the fan should start running immediately after the engine gets hot and once the coolant needs to be cooled down.
