Waiting for the vehicle to cool down before checking is important because many engine components can reach extremely high temperatures during operation. Checking fluids or components while the vehicle is still hot can lead to serious burns or injury, especially when dealing with engine oil, transmission fluid, or coolant. These fluids can be pressurized and may spew out when opened if the engine is hot, posing a safety risk.

While it is vital to check all fluids regularly, doing so safely involves ensuring the engine is cool. This practice helps maintain personal safety as well as the proper function of the vehicle, as hot emissions or components can provide inaccurate readings or even damage to the vehicle system when handled recklessly.
