Every 7,500 Miles
At every 7,500-mile mark or every six months, you should bring your Sierra in for its regular check-up. During this maintenance, your truck will get its tires rotated, a safety inspection, and its oil and filter changed. The mechanic will check the truck’s brakes, belts, and hoses, as well as look for any fluid leaks to ensure your Sierra is performing at its peak. Your truck’s engine coolant levels should also be checked, along with its windshield wiper fluid levels.
