Scheduled Maintenance for Your GMC: Ensuring Long-Term Performance

Regular GMC maintenance allows your vehicle to operate at peak performance and extends its life. As your GMC dealer, we want to tell you about a few examples of the types of maintenance we provide.

Examples of GMC Maintenance Available at Your GMC Dealer

Cabin Air Filter Replacement

This filter traps dirt, pollen, and other contaminants, preventing them from entering your cabin. It also filters AC air. This is important for health, as pollen or dust can cause allergic reactions or illness and make the air in your cabin feel heavy and stale. The filter will become clogged with dirt, and it’s usually changed every 15,000 miles, although this varies depending on your GMC model.

A blocked air filter also restricts airflow from the AC, preventing your cabin from cooling correctly. Dust trapped by the filter can damage your AC and heating systems, necessitating otherwise unnecessary repairs. Our technicians can easily replace this filter, and clean, cold air will fill your cabin again.

Ignition Coil Replacement

Ignition coils don’t get as much attention as spark plugs, but they’re equally vital. A spark plug screws into each cylinder and ignites the compressed fuel-air mixture at a precise instant to produce combustion. A spark plug, however, only produces 12 volts, which is insufficient to burn the fuel-air mixture. An ignition coil connects to each spark plug to boost this power.

A coil supplies 30,000 volts, more than sufficient to produce combustion. Coils wear out in time due to age and can be damaged by a fuel-rich engine, a worn spark plug, or electrical issues. A failed coil prevents a cylinder’s contents from successfully igniting, and you’ll experience misfiring, or your GMC could stall. We’ll test the coils and replace any damaged ones in minutes.

Starter Replacement

When you push the start button on your dash, the starter receives an electrical charge from your battery and cranks your engine. Air and fuel are drawn into the intake manifold to mix before entering the cylinders to begin combustion. Once combustion starts, the process continues until you switch your engine off. The starter is a robust component, but it can eventually fail due to age.

A failed starter prevents the engine from cranking, and your GMC won’t start. Unlike a dead battery, the starter can’t be temporarily brought to life with the equivalent of a jump-start. One of the most common causes of starter failure is a blown starter solenoid. The solenoid receives the battery’s electrical charge and passes it to the starter. Depending on the situation, we can replace a failed solenoid or install a new starter.
