Winter prep includes checking your battery (cold reduces its power), switching to winter tires for better traction and safety, topping off fluids with winter-grade formulas, checking brakes, inspecting wipers and lights, and ensuring your heating system works.

McHenry winters are no joke-icy roads demand peak vehicle performance. Slick roads are when good tires, strong brakes, and a reliable battery matter most. Don't wait until the first snowfall.

Castle Cadillac McHenry's Service Department offers comprehensive winter readiness checks. Our team knows what Cadillacs need to handle Illinois winters safely. **Call (779) 265-4427** in early fall to schedule a seasonal service-it's the best insurance against winter trouble.
