Regularly scheduled maintenance ensures worn parts are replaced before they fail and potentially cause damage. There are usually early warning signs that components need replacement. As your GMC dealership, we want to tell you a few signs you need to visit us for GMC maintenance.
Slower Starting
When you push the start button, you expect to hear the sound of your GMC engine within seconds. The battery sends an electrical charge that powers the starter. The starter then cranks the engine, beginning combustion and bringing the engine to life. If you notice your engine takes longer to start than it should, this is a sign that something is wrong.
Slow starting can be caused by an old, weak battery that can’t retain enough charge to power the starter. It could also be due to a failing starter solenoid or a weakening alternator. The starter solenoid activates the starter, and it will take longer to crank the engine if the solenoid is failing. The alternator recharges the battery, and a weak alternator may not fully recharge the battery. We find the cause of the problem and repair it.
Leaking Brake Fluid
Brake fluid is highly pressurized, and this pressure is essential as it must be capable of stopping your vehicle’s weight almost instantly, even when travelling at speed. As time passes, brake lines can rust and brake hoses can weaken, resulting in a leak. In addition, damage from hard objects thrown up from the road surface can also damage the brake system.
Brake fluid looks like cooking oil, so a leak is indistinguishable on many surfaces. If there is a leak, you’ll feel a lack of resistance when you push down on the brake pedal. If this happens, contact us ASAP, as low brake fluid can cause brake failure. We’ll find and fix the leak, then refill the fluid.
Misfiring
Misfiring occurs when the fuel-air mixture in a cylinder doesn’t ignite correctly. Fuel enters the intake manifold via the fuel injectors, and air enters through the engine air filter. Once they’ve been correctly mixed, they’re drawn into the engine cylinders. The mixture is compressed by the piston rising at speed, and then ignited by the spark plug to produce a regular series of precisely timed explosions that provide the energy that moves your vehicle.
A worn spark plug can cause a misfire since it can’t supply enough power, and the mixture will burn irregularly. A fuel-rich engine can also cause misfiring, as the lack of air prevents most of the fuel from burning. Our technicians will investigate and fix the problem.
Repairing a problem when it begins saves you time and money. Contact us today at Randy Bowen Chevrolet GMC in Chandler, AZ.
