Your vehicle’s engine makes a lot of heat when it’s powering you down the road, so it needs a way to get rid of that energy.  That’s why your vehicle has a cooling system, complete with a radiator and one or two radiator fans, also called cooling fans.  Those fans make sure air keeps moving across the radiator so that the heat stored in the coolant can be dissipated outside when the vehicle is stopped or not traveling fast.

Radiator fans can develop problems and can stop working properly or stop working altogether.  Some signs to look for? If you’re driving slowly and idling and you see your temperature gauge moving toward the red or hot zone, that could spell trouble.  Another thing you may notice when a radiator fan is failing is that there may be a loud noise coming from the engine compartment.

There are two types of radiator fans.  One is mechanically connected to the engine and uses the engine’s rotational energy to turn it.  The other is an electric fan and is the type used in most newer vehicles.  In the electrical type, one of the components, such as a relay or fuse, may fail, causing the fan to stop turning.  In the mechanical type, since it’s driven by a pulley/belt mechanism, one of those components may break or stop working properly.  A clutch can wear out or a belt may slip or break. 

When your cooling fan isn’t working properly, it may cause your engine to overheat which could lead to expensive damage. That’s why it’s important to make sure you visit your service facility if you notice any of these symptoms.  A technician is trained to diagnose the problem and make sure your radiator fan is doing its job.  When it comes to your vehicle, your radiator fan really is your biggest fan.

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. At Autotronics of St. Peter we know that the service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prevents the accessories from spinning properly, leading to premature wear and noise for St. Peter drivers.

Your vehicle manufacturer has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner and any idler pulleys your car might have. Your friendly and professional Autotronics of St. Peter service advisor can inspect your system and let you know if it’s time for a replacement.

Give us a call.

When it comes to your vehicle, it all starts with the battery. Proper battery maintenance is important for two reasons:

First, your vehicle won’t start or run without it. Second, it is the key to the long life of your auto electrical system. If your battery isn’t working efficiently, your alternator has to work overtime to make up for it, and other electrical components can suffer as well.

A number of years ago sealed batteries were introduced to the local St. Peter, MN, market. They were hailed as being ‘maintenance-free batteries.’ While it is true that you can’t get in and adjust the electrolyte levels of a sealed battery, it is by no means maintenance free.

Batteries are very sensitive to changes in the weather around MN. Temperature really affects auto battery performance. A battery inspection is an important part of your spring and fall checkups. Next time you’re under your hood, take a look at your battery.

• Is it clean and free of residue? A dirty battery will drain.
• Is there corrosion at the terminals where the battery cables attach to the battery? If there is, the corrosion can interfere with how efficiently electricity passes back and forth from the battery.
• Are the cables loose? Make sure they are tight.
• Are the cables themselves corroded? Corrosion can actually eat through the battery cables.

Autotronics of St. Peter service advisors can inspect and test your battery. If the inspection warrants a cleaning, have it done. If the battery test indicates that replacement of the battery or cables is in order, you will be lucky to have caught the problem before it becomes a major inconvenience.

Your battery will also last longer if you keep your fuel system and ignition system clean. It’s all part of your commitment to regular maintenance, to keep your vehicle running on St. Peter streets at its best for a long, long time.
