Key fluids to monitor include engine oil, coolant, brake fluid, power steering fluid, transmission fluid, and windshield washer fluid. Low or dirty fluids can reduce performance and damage your engine, so regular checks matter.

Most fluids should be checked every few months or before long trips. Your owner's manual specifies which ones and how often. Castle Chevrolet McHenry's Service Department checks all vital fluids as part of regular maintenance and can top off or replace fluids as needed.
