Just a quick tip on checking the car’s coolant level. While straightforward, it can be difficult actually seeing the coolant inside the tank, due to the tank’s opacity.
And for those who don’t know the location of the overflow tank, it is below the left (driver side) engine cover. Just pull it up and it will pop off.
You can try to transilluminate the tank, and that can work, but it is still difficult to see the coolant level.
A better way is to remove the cap and shine a flashlight into the tank. This obviously has to be done when the engine is cold.
The result is a much clearer view of the coolant level.
