Many drivers don't know much about the alternator. When it comes to the electrical system, the battery seems to get all the press. The alternator is a mini generator that produces electricity for your car and recharges the battery. Over time, parts of the alternator can become worn or damaged, and you'll need an alternator repair. As your Chevy dealer, we'd like to tell you some signs that you need to visit us for that repair.

Damaged Rectifier

The rectifier is a small component in your alternator that converts electricity. The heart of your alternator is a bundle of magnets bound with wire. As your alternator spins, the magnets generate magnetic energy. This energy is captured by the stator and turned into AC. Your car's electrical systems, however, require DC. The purpose of the rectifier is to convert this AC to DC.

If your rectifier is damaged, it won't be able to convert the electricity produced by the magnets. Without this conversion, your electrical systems will instantly stop working. Our technicians can check your rectifier for damage and replace it if necessary. A new rectifier will continue the conversion, and your electrical systems will work normally again.

Your Alternator Is Old

An alternator is a relatively long-lived component, with an average lifespan of eight years. The alternator works continuously while your engine is running to produce electricity. As the alternator ages, parts will wear out or get damaged. This leads to reduced electrical production, which affects your car's electrical systems.

Your car's systems have a fixed demand for electricity, and the gradually reducing power supply will cause electrical failures. These problems will eventually extend to the battery and prevent of from fully recharging. Our technicians can test your alternator and replace it with a new one if it's failing

Strange Noises

As a driver, you're familiar with the sounds of your car. Unusual noises from the engine are always a reason to worry. One of the signs of an alternator problem is strange noises like whining or grinding from the engine compartment. These noises will gradually become louder and louder as the problem progresses.

The alternator belt, for example, is responsible for powering the alternator. It does this by moving at speed over the alternator pulley, which then causes the pulley to spin to power the alternator. The belt can become damaged in time or can jam on a worn pulley. The whining sound you hear could be the fast-moving belt moving over the jammed pulley.

Your alternator will always give you a variety of signs that it's failing. If something doesn't feel or sound right, call us right away at Larsen Auto Center.

Chevrolet Air Conditioning Service: Staying Cool and Comfortable on the Road

Image via Larsen Auto Center. AC not working? No matter what time of year it is, a malfunctioning air conditioning unit in your vehicle can be inconvenient. In the summer, no AC can mean miserable car rides as you battle the heat, while in the winter, no AC can make it harder for your vehicle to de-fog your windows. Fortunately, you can schedule AC service at your Chevy dealer. more Depending on your AC unit's specific issue, a repair at your local dealership can take less than a day most of the time. Some issues, like low refrigerant, are easy to fix. All your Chevy mechanic will have to do is top off the refrigerant in your vehicle or use a special recharging system to address the issue. If your mechanic finds any leaks, it can be repaired during your service appointment. Other issues may be more complicated to fix, like a faulty climate control sensor. These sensors are designed to maintain a preferred air conditioner temperature, but when the sensors fail, you might end up with hot air from your AC unit. Replacing defective parts may require ordering parts that are designed for your specific model. Ask Your Chevy Dealer: Why Is Your AC Not Working? There are several reasons why your vehicle's AC system might fail. While the most common reason is usually related to leaking or low refrigerant, the root cause of hot air from your AC system may be related to the AC compressor. Some compressors fail as a result of blown electrical fuses, while others may turn off because of built-in safety features related to the pressure switch that monitors the refrigerant level. Old Cabin Air Filter A clogged cabin air filter is another common reason for experiencing AC problems. When the air filter is old or clogged, it cannot adequately deliver air to the AC unit, which can limit how well the AC unit can cool the air passing through various vents. Damaged Condenser The condenser is a crucial part of your AC unit that works to cool the refrigerant in your vehicle. Your condenser should be replaced every 10 years or so, but it may need to be replaced if it is damaged. Since the condenser in your vehicle typically sits at the nose of your hood, it may be vulnerable to damage from road debris coming through the front grille. Whether it's simple issues like a clogged air filter or more complex electrical issues, your Chevy mechanic can quickly fix your AC unit so you can get back on the road in comfort.

The Importance of Chevrolet Transmission Fluid Service: What You Need to Know

Image via Larsen Auto Center. When you get a transmission fluid service from your Chevy dealer, you can expect your vehicle to run more smoothly. Here's what goes into that service and how to know it's time. more What It Does Transmission fluid performs a similar function to motor oil in general. It's viscous and thick, and it lubricates all the gears within the transmission so they don't grind against each other. Over time, that fluid breaks down under the heat and friction of use, and that's why you sometimes have to get your transmission fluid changed out. Transmission Service Fluid Change The most basic service for your transmission is just to change its fluid. The drain plug is removed, the old fluid is drained out, we check the plug to make sure that there are no leaks, and then we refill your transmission with fresh, clean transmission fluid that meets your Chevy's specs. Fluid and Filter Replacement Your transmission also has a filter for the fluid to run through, and this is meant to prolong the life of the fluid by removing dirt, debris, and metal shavings. Naturally, this eventually fills up, so we will sometimes need to replace the filter for you and possibly replace the material in the gasket. Comprehensive Service Sometimes you need a more comprehensive service, and when that happens, not only do the fluids and filters get changed, but also each individual component of the transmission is inspected to make sure everything is working as it should. How to Tell You Need Transmission Service You Have Gear Slippage If you notice that your car seems to slip out of gear, especially when it's going up a hill, you need us to take a look at your transmission. You've Reached the Right Maintenance Interval Your Chevy owner's manual will have maintenance intervals for everything in the vehicle, including the transmission. Don't neglect these, as keeping up with maintenance is the best way to ensure you never have any issues with your transmission. You're Not Able to Smoothly Shift If your car is an automatic, you should barely even notice the shifts from gear to gear. If you're starting to feel a clunk, or it becomes very noticeable when the car changes gears, there's a problem. If you're driving a manual, you may notice that it feels hard to get into the required gear.
