What kind of fluids are typically checked during a Jiffy Lube service?

During a Jiffy Lube service, a comprehensive approach to vehicle maintenance is taken, which includes checking several key fluids that are essential for the vehicle's performance and safety. The correct choice highlights that engine oil, coolant, brake fluid, and windshield washer fluid are all inspected.

Engine oil is crucial for lubricating the engine components, reducing wear, and preventing overheating. Coolant is necessary for regulating the engine temperature and preventing it from overheating. Brake fluid is essential for the safe operation of the braking system, allowing the driver to stop the vehicle effectively. Windshield washer fluid is important for maintaining visibility, ensuring that the driver can see clearly while driving.

The other options limit the types of fluids checked, not providing the full scope of maintenance typically performed during a Jiffy Lube service. By including only a subset of fluids, they do not accurately represent the thoroughness expected in such services.
