What should you use before checking or replacing any engine fluid?

Before checking or replacing any engine fluid, it is essential to use the hood-release lever to open the vehicle's hood. This step is necessary as it provides access to the engine compartment where various fluids can be checked or replaced, such as oil, coolant, brake fluid, and windshield washer fluid.

Using the hood-release lever ensures that you are safely able to access the engine area without causing damage or injury. Once the hood is open, you can then proceed to check or replace the fluids as needed. Accessing the engine compartment without using the hood-release lever could lead to injuries or improper handling of the components, underscoring the importance of this initial step.
