Chilly Warning (Diagnosing a Noise in Cold Vehicle)

When the weather gets colder, sometimes the noises your vehicle makes will change.  For example, you may notice a whining sound when you get going in the morning.  It may go away when the vehicle warms up, but it's best not to ignore that sound because it could be a warning of worse things to come.

Colder temperatures cause different components to behave differently.  Let's take a look at a few of them.  First, the fluids in your vehicle.  Cold temperatures can make them behave a little differently, such as engine oil, transmission fluid and power steering fluid. Those characteristics could change if the fluids are older and full of contaminants.

Belts also can create a whining noise when cold.  Since they turn pulleys that move other things, several factors can create issues.  Increased friction can change proper tensions on belts.  Plus, belts change as they age and may crack, get loose or develop a glazed surface. Belts and pulleys also must be aligned properly to work the way they're designed to.

As you can imagine, it's easier for a technician to diagnose a noise if the vehicle is making it.  And if a vehicle only makes a noise when it's cold, that sound may be gone by the time the vehicle makes it to the repair facility.  That means a driver may have to consider dropping off the vehicle the night before so the technician can be the first to start it the following morning.  Most service facilities can accommodate that with either a drop-off box or other arrangement.  Heed your vehicle's warning when you start to hear unusual noises.  That's a cool idea you should be able to easily warm up to.

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!

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.

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.

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.
