3 GMC Fluid Services That Keep Your Vehicle Moving Smoothly

Every driver knows that regular oil changes are important, but your GMC contains many other fluids that must be checked and replaced when necessary. As your GMC dealership, we want to tell you more about some of our fluid replacement services and why changing them regularly is essential.

Coolant 

Your engine works most efficiently at a temperature between 185 °F and 230 °F, but continued high temperatures are dangerous. The head gasket, which prevents the fluids in the upper and lower engine sections can crack, allowing the fluids to mix and cause serious, even permanent, engine damage. Coolant helps prevent this by absorbing engine heat and transporting it to the radiator for removal by heat exchange.

Coolant loses its effectiveness over time, allowing the engine temperature to increase. It's usually replaced every 30,000 miles to ensure it keeps the engine from overheating. In addition, older coolant can become corrosive and damage the engine. We can replace your coolant in minutes, and if the old coolant is corrosive, we'll drain it, flush the cooling system, and install fresh coolant.

Brake Fluid

Brake fluid provides the hydraulic power that allows the brakes to work. When you hit the brakes, this pressurized fluid is forced through the hoses to the calipers. The brake fluid pushes the pins out of all four calipers simultaneously, and the calipers close on the wheel rotors. Brake pads inside the calipers generate friction, which stops the wheels.

This fluid is also usually replaced every 30,000 miles. Older brake fluid absorbs water, and if you have to brake frequently within a short time, the water can overheat and boil. The boiling water creates air bubbles that block the hoses and brake lines, preventing one or more calipers from closing. This situation also causes the brake fluid to overheat, and your brakes can fail. We drain and replace the fluid regularly to prevent this from happening.

Transmission Fluid

Transmission fluid protects the transmission components from damage by surrounding them with a protective coating. This allows them to work fast and efficiently while minimizing wear and tear. This fluid also provides the hydraulic power needed to shift the gears smoothly and silently. Transmission fluid is usually changed every 30,000 to 60,000 miles. The correct replacement time for your GMC model is listed in your vehicle manual.

Older transmission fluid loses many of its special properties and its heat resistance. The transmission is a hot environment, and older fluid can overheat and burn. This will damage the transmission, and the burning fluid can't supply hydraulic power, and the gears won't shift.

If you need to replace these or any other fluids, contact us at Gerald Jones GMC in Graniteville, SC.

Expert Guidance on EV Battery Service in Graniteville, SC

Electric vehicles (EVs) have rewritten the rulebook on driving. They’re smooth, quiet, futuristic — and powered by a battery that basically carries the weight of the entire operation. When that battery is healthy, your EV feels unstoppable. When it’s struggling, the entire driving experience falls apart quicker than a cheap lawn chair. For drivers in Graniteville, SC, taking EV battery care seriously isn’t just a suggestion — it’s the secret to keeping your vehicle performing like the advanced machine it was built to be. Gerald Jones GMC is the local go-to for keeping that powerhouse under the floor humming the way it should. more Why EV Battery Service is Essential An EV battery is more than a component — it is the vehicle’s performance. It stores every bit of power your car will ever use, and over time, heat, cold, charging habits, and everyday driving slowly chip away at its capacity. If you ignore it long enough, you’ll eventually find yourself coasting to a stop with a dashboard lit up like a Christmas display. Graniteville’s climate only adds to the challenge. Summer heat can drain efficiency, and unexpected cold snaps make the battery work even harder. Routine diagnostics check capacity, health, temperature management, and charging performance — catching issues before they decide to ruin your morning commute. Signs You Might Need an EV Battery Replacement A well-maintained battery lasts for years, but even the best ones don’t last forever. When it starts aging out, your EV sends signals that are impossible to ignore. Reduced Range: If you’re suddenly getting fewer miles than your daily coffee run, that’s not “normal wear.” That’s your battery telling you it’s tired. Longer Charging Times: Charging shouldn’t feel like an entire afternoon activity. When it drags, something’s off internally. Warning Lights: EVs don’t whisper — they announce problems. Loudly. Pay attention. Visible Damage: Extremely rare, but if you ever see physical damage on the battery housing, pause everything and get it checked. Immediately. Gerald Jones GMC specializes in identifying these issues with precision and recommending replacements only when absolutely necessary. Maintaining Your EV Battery's Health A few smart habits can add years — yes, years — to your battery’s lifespan. Avoid Extreme Temperatures: Heat cooks batteries. Cold slows them down. Parking in shade or using a garage does more good than most drivers realize. Charge Smart: Keeping the battery out of the extreme ends of its charge range slow capacity loss over time. It’s an easy habit that pays off. Use Certified Technicians: EV batteries are not DIY projects. One wrong move and suddenly things get expensive. Professionals ensure accuracy and safety, every time. Across Graniteville, SC, EV drivers trust Gerald Jones GMC for diagnostics, maintenance, and full battery replacements when needed.

Routine Tire Maintenance Tips for Graniteville, SC Drivers

Routine tire maintenance is one of those things every driver knows they should do, yet it somehow ends up behind “clean the garage” on the to-do list. The truth is: tires make or break your vehicle’s safety, efficiency, and overall driving experience. Well-maintained tires mean stronger traction, better fuel economy, and a smoother ride — especially across the mix of roads you'll find around Graniteville, SC. Ignore them long enough, though, and you’re looking at uneven wear, sluggish performance, and the kind of blowout that turns a calm afternoon into a roadside rubberneck. Following a simple maintenance routine keeps you safe and saves you from repairs that always seem to show up at the worst possible time. more Key Steps for Keeping Your Tires in Great Shape Stay on Top of Tire Pressure Keeping your tire pressure in the proper range is one of the simplest, most powerful ways to extend tire life and improve your vehicle’s handling. Under-inflated tires sag and drag, burning extra fuel. Over-inflated ones stiffen up and lose grip. A quick check with a tire gauge each month is all it takes to avoid both extremes. And in Graniteville, SC, temperature swings can make pressure rise and fall like a roller coaster — colder mornings drop PSI, warmer afternoons raise it. Regular checks keep things balanced and your drive predictable. Keep Up With Tire Rotations Tire rotation spreads out the workload so no single tire gets bullied into wearing out faster than the others. Since front and rear tires handle different stresses, rotating them every 5,000 to 7,500 miles keeps tread wear even and extends their lifespan. Many drivers pair rotations with oil changes, making it an easy two-in-one maintenance routine. At Gerald Jones GMC, our technicians can handle this service quickly and precisely, keeping your tires in top shape. Make Tread Depth a Priority Tread depth has one job: help your tires grip the road. When it thins out, everything from braking to cornering gets worse — especially on wet pavement. The trusty penny test still works: place a penny into the tread with Lincoln’s head facing down. If his head is fully visible, those tires are finished. Drivers around Graniteville who frequently travel highways or rougher terrain should check tread depth more often, as those conditions tend to wear tires down faster. When Professional Tire Care Is the Right Move Some maintenance tasks are perfect for DIY. Others are not. If you notice any of the following, it’s time to bring in a professional: Persistent vibration while driving — often a sign of alignment issues. Uneven tread wear — which may point to balancing or suspension concerns. Low tread depth or visible damage like cuts, bulges, or punctures. Our certified technicians at Gerald Jones GMC have the tools and training to diagnose issues accurately and recommend the right solution, from simple repairs to full replacements. Trust Gerald Jones GMC for Tire Service in Graniteville, SC Routine tire maintenance keeps your vehicle safe, efficient, and ready for the road ahead. By monitoring tire pressure, rotating your tires, and keeping an eye on tread depth, you’ll extend tire life and improve everyday performance. When you need expert tire service, the team at Gerald Jones GMC is here to help you stay ahead of problems before they start.
