Seasonal maintenance keeps your Subaru running safely year-round. Our Service team recommends checking fluid levels, battery health, and brake condition before winter, and reviewing coolant and air-conditioning readiness as summer approaches. Winter often calls for tire rotation and winter-grade tire changeover; summer can involve transmission fluid checks and AC service.

We handle all seasonal prep work here at Castle Subaru McHenry-no need to shop around. Our technicians know Subaru inside out and use genuine parts and fluids. Call **(779) 601-0797** to schedule your seasonal inspection, and we'll walk you through what your vehicle needs. It's a straightforward way to avoid surprises and keep your warranty intact.
