3 Signs You Need Maintenance at Your Chevy Dealership

Thudding Noises

Your Chevy engine is very quiet as it runs, so if you start to hear thudding noises as you drive, something is wrong. The usual cause of these strange noises is a damaged engine mount. The engine generates enormous power and has to be securely connected to the frame to prevent it from moving and damaging itself. The engine’s sensitive components must also be protected against vibrations caused by driving.

Two rubber, liquid-filled engine mounts lock the engine in place. Their liquid fillings absorb vibrations and keep the engine steady. In time, the rubber can crack, and the liquid will leak. If this happens, your engine remains connected to the frame but will move slightly up and down, causing thudding noises. We’ll replace one or both mounts to fix this problem.

Battery Warning Light

The battery warning light on your dash looks like a line drawing of a battery with “+” and “-” signs. It automatically lights up when your engine starts and then should go out to signal all is well. If the light remains on, it means something is wrong with the electrical system. Almost every system in your Chevy needs electricity, and electrical problems can rapidly spread depending on the original cause of the trouble.

A worn alternator, for example, will trigger the warning light. The alternator generates all the electricity your Chevy needs. As the alternator ages, it slows down and supplies less power. As the power supply continues to drop, your battery won’t recharge sufficiently and could fail. In addition, random electrical issues will appear frequently. Our technicians will examine the electrical system and fix the problem.

Misfiring

Misfiring happens when the fuel-air mixture in a cylinder doesn’t burn correctly. Correct burning occurs when the mixture is ignited at a precise moment. This causes it to produce a series of regularly timed explosions that generate the energy that moves the wheels. Damaged valves, worn piston heads, shrunken seals, or a fuel-rich engine can all cause misfiring. In all these cases, continued misfiring will cause engine damage.

A damaged intake valve in a cylinder can allow additional air to enter the cylinder. The cylinder has to be airtight for combustion to compress the fuel-air mixture. If more air enters, it alters the fuel-air mixture and reduces compression. This can cause a misfire when the spark plug ignites the mixture. We’ll find the cause of the misfire and fix it.
