Some drivers don’t realize how important the alternator is. It’s understandable, as most people automatically think about the battery if they have an electrical problem. The alternator in your Chevy is a small generator that produces electricity for your car. It’s also responsible for ensuring your battery is always charged to start your engine. If your alternator has a problem, it’s time to visit your friendly Chevy dealer for an alternator repair.
Bad Belt Tensioner
A screeching noise from the engine compartment may be a sign the alternator belt is loose or damaged. The alternator belt connects to the crankshaft. The crankshaft turns as your car moves, which causes the alternator belt to move at speed. The belt runs across a series of pulleys, one of which is connected to the alternator. The belt’s movement causes the pulley to spin, and this powers the alternator.
All belts must have the correct tension to operate effectively. A belt that’s too loose will reduce the speed of the alternator, which affects its ability to generate power. If the belt is too tight, it could snap, and the alternator will fail. The belt tensioner is designed to keep the belt at the correct tension at all times. The screeching sound could mean the tensioner is damaged. We’ll examine the tensioner and repair or replace it.
Electrical Glitches
If you’re experiencing random electrical problems like components that refuse to work or move slowly, your alternator may be going bad. A healthy alternator produces more power than your Chevy requires, and this ensures all the systems operate correctly. When an alternator starts wearing out, its electricity generation gradually reduces.
Electrical problems may not be noticeable a first. A small issue like a radio that refuses to switch on and then suddenly works can pass unnoticed. As the level of available power drops, these problems will become more frequent. Electrical issues can even target critical systems like spark plugs. We can test your alternator and replace it if necessary.
Smells and Noises
A worn alternator will still attempt to supply enough power for your car. It will do this by forcing itself to spin faster. The faster movement will cause additional damage to the alternator, and it will begin heating up. You might smell a hot, metallic smell as the alternator starts to overheat.
The faster movement also places pressure on various parts of the electrical system. You may hear squealing, grinding, or clunking noises. These noises are all signs that your alternator is failing and will need replacement.
You’ll always see signs that the alternator is failing. If you suspect there’s a problem, call us right away at Cheraw Chevrolet.
