Your Biggest Fan (Radiator Fan Problems)

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.

No Fountain of Youth (Aging Tires)

Can you think of anyone who enjoys aging?  Wrinkles where you don't want them, gray hair, eyes that won't focus any more, no stamina. 

Believe it or not, your tires age, too, and they don't get better the older they get.  And here's the important thing to know, even if they can still pass a tread depth test, they may simply be too old to be safe 

Here's the best way to understand this.  Have you ever found an old deck of playing cards with a rubber band wrapped around them?  Try stretching the rubber band.  SNAP! It's all cracked and brittle.  And you haven't stressed that rubber one bit since the time you put them in that drawer.

Now you know what's happening to your tires.  Rubber ages.  Just like us, the day we come into the world, we start to go downhill (no pun intended).  Oh, engineers are able to make a tire last longer than ever before.  But that gas that keeps us alive—oxygen—seems to love to chemically mix with some components in rubber.  Oxidation causes rubber to become hard and brittle.  The rubber band test.

Is there an age test that can tell you when a tire is tool old to roll? Well, not really.  They don't all age the same.  Hot climates can make tires wear out more quickly.  Some experts say a tire can last up to 10 years but should be inspected every year after the age of five.  Others say tires should have an expiration date at six years old.

Since no one would ever ask a tire its age, how do you know how old one is? Believe it or not, tires made after the year 2000 have a date code stamped on either the inside or the outside of the sidewall.  It's a four-digit numbers; the first two tell you the week, the second two tell you the year. So if it has the number 1916, it was made in the 21^st week of 2016. 

Another way to find out if your tires still have enough life in them is to have your vehicle service facility inspect them.  They look for signs of age, such as developing cracks in the rubber, the condition of the sidewalls and, of course, that old standby: tread.  If it's time to "retire" them, discuss options with your service advisor.
