When your vehicle doesn't start, the first thing you think of might be the battery. That may be the culprit, but it also might be that your alternator has gone bad. An alternator sends power to your vehicle's electrical systems and accessories like your entertainment system, charging ports, and so on. Any extra electricity goes to re-charge the battery. So, your battery is what gets your engine started, but once the engine's running, your alternator is what's turning out the power. A failing alternator may not be able to keep the battery charged. One of the most common causes of an alternator's demise is the bearings fail and seize up. That can happen from dirt and liquid getting into the bearings combined with the heat of the engine. You might hear a grinding sound, an early warning that something's wrong. Other signs your alternator may be failing? A squealing noise in your engine, or your headlights dimming when engine RPMs drop. You may notice an electrical smell coming from the engine. If any of these are happening, you'll want to have your vehicle checked at your NAPA AutoCare Center. Many modern alternators have a decoupler pulley that allows the alternator to rest when it isn’t needed. This extends alternator life and helps with fuel economy. A bad decouple pulley could cause your battery to go dead. If your alternator needs to be replaced, you should also replace the serpentine belt that turns it, and the belt tensioner as well. As you can imagine, if the alternator isn’t rotating as it should, the belt that turns it won't freely move, and that can cause excessive belt wear. The service advisor at your NAPA AutoCare Center will recommend the right replacement parts based on your vehicle's needs and your driving habits. And remember, if you notice any of those warning signs that the alternator might be going bad, it's always better to have it checked out, so you don't find yourself stranded on the road.

The thermostat is part of your cooling system. JEFFERSON CITY residents' vehicle thermostats perform a similar function to the thermostats in their homes. At home, you set your thermostat to maintain a comfortable temperature range. When your home gets too hot, the air conditioning kicks on and when it gets too cool, the heater turns on. Now your engine also has an optimal temperature range: warm enough to run efficiently and not so hot as to cause engine damage. Your vehicle's thermostat is a valve between the engine and the radiator. When JEFFERSON CITY residents first start a cold engine, the valve (thermostat) is closed, allowing the coolant surrounding the engine to warm up to the proper operating temperature. As the coolant gets hotter, the thermostat opens, allowing coolant to flow through to the radiator to be cooled. The thermostat opens and closes to keep the engine within a certain temperature range. Now thermostats are rated for a specific temperature depending on the engine – not a one size fits all proposition. Thermostats are subject to normal wear. Proper operation depends on a special wax that expands as it heats up to open a spring-loaded valve. A worn thermostat could stick in the open position causing the engine to run too cool. This is inefficient and could affect performance and fuel economy. If a thermostat sticks in the closed position, the engine can be subject to the results of overheating. There isn't a specific routine for JEFFERSON CITY residents to maintain their thermostat, but maintaining the cooling system by changing the coolant/antifreeze on schedule will make sure the coolant has enough corrosion inhibitors to protect the thermostat and other system components. Cooling system experts and the team at Frosty Auto Clinic in JEFFERSON CITY recommend replacing your thermostat when you do a coolant flush or exchange. Also, thermostats usually wear out faster than your hoses, so if a worn hose replacement is performed, replace the thermostat at the same time. If your temperature warning light comes on, have an inspection of your cooling system right away. This could be a thermostat . The thermostat could also be the culprit for JEFFERSON CITY residents who aren't getting hot air when they turn on their heater. The thermostat is a relatively inexpensive part that stands guard between you and catastrophic engine damage. Follow your owner's manual instructions, or check with your friendly and knowledgeable Frosty Auto Clinic service advisor to see if it's time for a cooling system inspection or service.

A lot of people in MO have older vehicles. They're good commuters, grocery-getters or toy-haulers. They enjoy that fact that they're paid off, or soon will be. They would gladly like to keep their vehicles for 200,000 miles/320,000 kilometers or more – as long as it's economical to do so. There are plenty of people in JEFFERSON CITY whose vehicles are running after 150,000 or 200,000 miles (240,000 or 320,000 kilometers). We can learn from what they're doing to keep our own cars on the road. A common denominator is that they never skip an oil change. That may sound a bit unsophisticated, but it's really not. First off, oil is the life blood of your engine and it needs to be clean to properly lubricate. Skipping oil changes leads to clogged oil filters and sludge that can damage your engine. Enough said. There's another reason the scheduled oil change is so important. It's simple — a Frosty Auto Clinic professional is going to be looking at your car. All of your fluid levels will be inspected and topped off so they won't get so low that damage can be done. If there is a significant fluid loss — let's use brake fluid as an example — your JEFFERSON CITY technician can look for the cause of the loss and find the problem before it leads to an accident or costly repair. Your JEFFERSON CITY service technician will also visually inspect the vehicle for worn belts and hoses, uneven tire wear, leaking shock absorbers and more. Problems get addressed before they lead to repairs that cost more than the car's worth. And your JEFFERSON CITY service advisor will be able to remind you of other services that the factory recommends you get done. Just think of that oil change the same way as you do about going to the dentist for your six month cleaning and checkup. Don't skip it. Of course, good maintenance costs money, but it's far cheaper than new car payments. Give us a call to schedule your next oil change today. You can find us online at Frosty Auto Clinic, or you can find us in JEFFERSON CITY, MO 65101, at 310 VETERANS LN. Or simply give us a call at 573-635-1767.

Most in the area may not know much about transfer cases, but if you have a four-wheel drive vehicle, you've got one. It makes sure you have power available for both the front and rear axles when driving around MO. For example, if you have a rear-wheel drive SUV, power goes to the rear wheels until you need four-wheel drive. That's when the transfer case steps in and transfers some of the power to the front wheels as well. You might use a shift lever to go into four-wheel drive, it could be a button on the dash or it might even go into four-wheel drive automatically, depending on your vehicle. The transfer case is serviced at Frosty Auto Clinic by periodically draining its fluid and replacing it with fresh fluid. We also check for leaks and damage. Transfer case fluid cools and lubricates the gears, chains, bearings, shafts and other parts for JEFFERSON CITY motorists. Over time, the additives in the fluid wear out and it doesn't protect as well. Also, bits of metal and clutch material wear off and contaminate the fluid. There isn't a filter in the transfer case, so if JEFFERSON CITY drivers allow the contamination to stay for too long, it'll further accelerate wear. Now, your owner's manual may not have a recommended interval for when you should change your transfer case fluid – so ask your JEFFERSON CITY service advisor at Frosty Auto Clinic. There are several things that affect how often you should change the fluid, so tell her how often you use four-wheel drive: if you drive in wet JEFFERSON CITY environments like places you cross streams or drive through mud and snow. That kind of stuff really shortens the drain interval. Transfer case parts will eventually wear out and you'll have to make repairs. But properly servicing your transfer case at Frosty Auto Clinic will keep that day as far in the future as possible. Call us today. Read the original article on the NAPA website.
