At Arnie Bauer Buick GMC, we know that regular oil changes and tire rotations are the basics of keeping your vehicle running smoothly. But what about the other services your Buick or GMC needs to stay reliable for years to come? Around 30,000 miles, it’s important to start considering key preventative maintenance like brake fluid flushes, coolant service, filter replacements, and transmission fluid flushes. Ignoring these services can lead to costly repairs down the road — and even shorten the life of your vehicle.
Whether you drive a Buick Encore GX around Matteson or a GMC Sierra for work, these often-overlooked maintenance items are just as important as the basics in keeping your vehicle performing at its best.
1. Cabin & Engine Air Filters
Dirty filters reduce airflow, hurt fuel economy, and make your HVAC system work harder. Cabin air filters keep dust, pollen, and contaminants out of your vehicle’s interior, while engine air filters protect your engine from harmful debris. These should be checked regularly and replaced as needed — especially if you drive in dusty or rural areas around Matteson and the surrounding Chicagoland suburbs.
2. Brake Fluid Service
Brake fluid absorbs moisture over time, which can lead to corrosion in your brake system and reduced stopping power. We recommend a brake fluid flush every 30,000 miles or 2–3 years (depending on your driving habits) to keep your brakes performing safely — especially during Illinois winters when road salt can speed up corrosion.
3. Cooling System Service
Your engine’s coolant doesn’t just keep it from overheating; it also protects against corrosion inside your radiator and engine block. Over time, coolant breaks down and loses its protective qualities. Starting around 30,000 miles, flushing and replacing it helps prevent overheating, freezing, and costly engine repairs.
4. Throttle Body Service
A dirty throttle body can cause rough idling, poor acceleration, and decreased fuel efficiency. Cleaning it ensures smooth airflow into the engine, which improves performance and helps your Buick or GMC run like new.
5. Transmission Service
Transmission fluid keeps your gears shifting smoothly, but it breaks down over time — especially if you tow, haul, or drive in heavy traffic. For most Buick and GMC models, we recommend a transmission flush around 30,000-60,000 miles to help avoid expensive transmission repairs later.
5. Fuel System Cleaning Service
Over time, carbon deposits can build up in your fuel injectors, intake valves, and combustion chambers, reducing engine performance and fuel efficiency. A fuel system cleaning service helps remove these deposits, ensuring proper fuel flow and cleaner combustion. This service can improve acceleration, restore lost power, and even help lower emissions.
We recommend considering a fuel system cleaning around 30,000 miles or sooner if you notice sluggish performance, rough idling, or decreased gas mileage. Keeping your Buick or GMC’s fuel system clean not only enhances performance but also helps extend the life of your engine.
