Some fluids to check include engine oil, transmission fluid, brake fluid, engine coolant, and power-steering fluid. Specialists recommend checking them at the same time as your oil change or every month or two.

Most vehicles have tire pressure sensors, but not all do. If your vehicle doesn’t have a sensor, you can check your tire pressure once a month or if there is a drastic change in temperature.

You can have your brakes checked when you rotate your tires. A mechanic can check the thickness of your brake pads to ensure that they are running at peak conditions.

Repairs can get high, but you can list your hourly rates, rates for common services, and so forth. You can also advise that you can offer written estimates if necessary.
