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.

H20 No! (Driving Through Standing Water)

In a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road.  It can be a daunting and frightening situation.  Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation.

Here a sample of one vehicle manufacturer's guidelines on what to do.  First, the vehicle is designed to go through some water, but you must be careful.  Never attempt to drive through water deeper than the bottom of your tires.

You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away.  You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly.  In swift moving storm runoff, your vehicle could literally be floating away with the current, putting your life and those of your passengers in mortal danger. 

Never go more than 5mph/8 km/hr when you drive through standing water.  That minimizes the waves you create.  If you DO find yourself in water that is touching your drivetrain components, that water can damage them.  And if you get water in your engine, it can lock up in seconds and stall.  The potential damage can be catastrophic.

You may have found yourself driving in water deep enough to reach your drivetrain components, and it's essential that you have a technician check the fluids to make sure they haven't been contaminated.  That includes engine oil, transmission and axle.  Driving with fluids contaminated with water can severely damage those components. 

The bottom line is to avoid driving through water at all if you possibly can.  Check your vehicle's owner's manual to see if there are specific guidelines for driving YOUR vehicle in standing water.  It's information that could save your life.

Not-So-Common Sense (Sensor Failures)

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works.

You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. 

Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly.

Here's an example of a sensor doing its job.  Your engine needs oil to lubricate metal components so the friction doesn't damage them.  Your engine has an oil pressure sensor that tells a computer called the Electronic Control Unit (ECU) if things are good to go or if there's something wrong, maybe the oil pressure is too low to keep things lubricated.  If it is, it gives a signal for the vehicle not to start, protecting the engine. 

Of course, the sensors can go bad, too, with some of the same results.  And so someone has to figure out if it's the sensor that's failed or if it really has detected a problem.  That is the challenge for technicians with specialized equipment to decipher the signs.  If a bad sensor is found, it may need to be replaced.  Sometimes a thorough cleaning can do the trick.  In either case, your service facility can track down the problem and get you back on the road.  Makes sense, doesn't it?

Growing Old Together (Maintaining an Older Vehicle)

More and more of us are hanging on to our vehicles longer.  A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years.  Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles). 

In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it's around 15.  Vehicles are lasting longer these days, and there are several reasons for that.

One expert cites better technology and overall quality improvements.  While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber.  They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy.

Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficient with better performance.  Those factors also contribute to a longer-lasting powertrain.  In fact, it's not unusual to see a powertrain easily last 150,000 miles/250,000 kilometers or more with no major failures.

Drivers are also taking their vehicles in more regularly for periodic maintenance.  Choosing one service facility for all your maintenance can contribute to your vehicle's longevity, too, since technicians know your vehicle's repair and service history.

If you bought your vehicle taking out a 5-year loan and you keep it 11 years, you've managed 6 of those years without a payment, always a nice feeling.  Plus, a bonus is that you get very familiar with every aspect of that vehicle's sounds, smells, handling, stopping characteristics, visibility and limitations.  And the more familiar you are with your vehicle, the more confident you can be as a driver.

Unlock the Secret (Malfunctioning Door Lock Actuator)

What a convenience power door locks are on a vehicle.  The latest don't even require you to push the button on the key fob; all you have to do is have it with you.  But sometimes there's a component of power door locks that can fail, especially when they are used several times each day.  Those are called the door lock actuators.

The actuator is an electric part that works with others (like motors and gears) to lock and unlock doors.  You can hear them work, sometimes with the little whirr of the gear or the quiet clunk of the lock finishing its cycle.  And it's good to pay attention to that sound because if it starts to sound different, it could be a signal that your lock is on the brink of failing. Another sign of a failing power door lock actuator is they start working intermittently or quickly and erratically.  The driver's door is often the first to start acting up since it's the one that usually gets the most use.

When you start to notice these signs, consider a visit to your service facility to get your vehicle checked out.  If you wait too long, you may find yourself getting locked out of your vehicle. Many vehicles do have mechanical keys available as a failsafe so you are at least able to get inside.  Some of them are hidden inside the key fob and you should know how to access them.  Check with your owner's manual or ask your service advisor.

It's extremely inconvenient to have to unlock your vehicle with the mechanical key, then get inside and unlock the other doors. It's even more inconvenient if you have passengers in the rear seats.  And that doesn't even count having to go through the same thing to lock the doors when you arrive at your destination.

There are many things that can cause power door locks to malfunction, but if it turns out to be a power lock actuator, the most common remedy is to replace it.  Some are easier for technicians to reach than others, depending on your vehicle's design.  But once your locks are working again, you might think you've found the "key" to happiness!
