The Puzzling Puddle (Leaks Under Vehicle)

Ever notice a little spot of liquid under your vehicle after you've parked in your driveway or garage? It may have been something as simple as water left from air conditioning condensation.  But then again, it could be a sign that there's trouble brewing in one of your vehicle's systems.

You can help your service facility diagnose the problem by getting a little sample of the drip.  At the same time, you may save yourself a tougher clean up task by preventing the leaky fluid from really messing up the driveway or garage floor.  The first thing is to put something under the vehicle. A flattened out cardboard box will do fine.  You may also want to slip a little disposable aluminum tray or pan under it to catch a bit of the fluid.  Chroma and consistency can help a technician quickly figure out what kind of fluid you're dealing with.  You can take your sample with you when you go to your service facility.

Also note how much of the substance is there over what period of time, when you started to notice it and its location relative to the vehicle.  Is it on the passenger's or driver's side? Front, middle or back? Vehicle's have different designs, so where their equipment is located will depend on make and model. 

The leaky fluid will have a certain look to it and consistency.  If it's blue, it may be windshield washer fluid and a sign that your washer fluid tank has a leak.  If it's green, it could be antifreeze.  Orange may mean rusty water or transmission fluid.  Brown? Might be oil.

There should be no leaks in your powertrain if things are maintained properly.  A small leak may not seem like a big deal, but sometimes they can get much bigger quickly.  A coolant leak, for example, may suddenly go from pinhole to flood, draining your cooling system and putting your engine in danger of overheating. 

It is a really good idea to have a professional check out your leaks as soon as you notice them.  And the more clues you can provide, the happier the technician will be as the search for the problem gets underway.

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.

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.

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?

Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key."

You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of:

• When is the problem happening, when the engine is cold or when it's been running for a while?
• Does the rough idling occur when I'm accelerating or when I'm going at a steady speed?
• Does it happen at high speeds?  Does it happen low speeds? Does it happen at both?

Make sure you describe the problem in as much detail because it will help a technician diagnose the problem.

One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN eventually wear out.  Inspecting the firing end can help the technician figure out the root of the problem.  Corroded or worn out spark plug wires, too, can contribute to an idling irregularity. 

There are other potential problem spots, too.  The technician may check the ignition coil, timing piston rings, valves and cylinder walls. 

If the mixture of air and fuel isn't correct, that may affect how smooth your vehicle is running.  Your service facility is equipped with diagnostic equipment that helps them pinpoint the problem.  Once that idle is smoothed out to the way it used to be, you'll be the smoothest operator on the road.
