How Often Should I Change Automatic Transmission Fluid?

The amount of time between automatic transmission fluid changes will depend on your model and how you drive. Your owner’s manual will have specific guidelines for you to follow. It’s important to follow your vehicle’s specific maintenance schedule, because fluid replacement timelines can vary.

How Often Should I Replace My Brake Fluid?

Your brake fluid requires more frequent replacement to ensure that your brakes work effectively. This service is generally recommended every two to three years or 30,000 miles, whichever comes first. You may need this sooner if you notice mushy brakes or you need to press harder to come to a stop.

How Often Should I Change the Coolant in My Car?

Coolant keeps your engine and powertrain running at the optimal temperature at all times. That’s why you need to take care of your coolant, which deteriorates over time and can’t regulate your engine as effectively. You should change the coolant in your vehicle every five years or 60,000 miles if you drive a new car, or more frequently for an older model.
