Your Cadillac uses several essential fluids: engine oil, coolant, transmission fluid, brake fluid, power steering fluid, and windshield washer fluid. Each has a recommended service interval to ensure peak performance and longevity.

Fluid levels and condition should be checked regularly. Flushing intervals depend on your model and driving conditions-some fluids may need service every 30,000-60,000 miles, while others last longer. Your owner's manual provides the exact schedule for your vehicle.

Let our Service Department handle the details. Call (779) 265-4427, and we'll review your Cadillac's fluid needs and create a service plan. Using genuine fluids keeps everything running smoothly.
