Breathe New Life into Your Engine (MAF sensor replacement)

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor.  You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues.

All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor.  If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall.  Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professional, so you’ll know what’s going on.

When you take your vehicle into your service facility, a technician will thoroughly check the system to see just where the problems are.  If your air filter is dirty, your MAF sensor may get dirty too, which might be causing the problems.  You may find your fuel economy isn’t what it used to be either.

There are other things that can cause the same symptoms, too, such as a leak in a vacuum hose. It’s also possible that the electrical connector between the MAF sensor and the engine has broken. 

The technician can use electronic diagnostic equipment to help pinpoint the exact problem or problems, replace worn parts, and test drive your vehicle to make sure it’s working correctly.

It’s also a good idea to make sure your air filter is changed regularly. A dirty air filter can contribute to a MAF sensor failure. One of the big benefits of having your vehicle regularly maintained at one facility, is they know your vehicle. So, they keep track of which of your vehicle’s parts should be periodically replaced before problems develop. 

If you keep clean air heading into your engine, it can help your engine work efficiently, and with the power it was engineered to deliver. Isn’t that a breath of fresh air?

Cold Weather Vehicle No-Nos (Items to Avoid Storing in a Freezing Vehicle)

It's always easier to leave a few things in your vehicle so you'll have them on hand.  But in cold weather, while it's a good idea to carry items such as a phone charger, blanket and shovel, there are some things you shouldn't store in your vehicle.

• Medicines and drugs.  Cold temperatures can affect the chemical makeup of some drugs.  Avoid leaving them in a vehicle, especially those in a liquid form like insulin, eye drops and cough syrup.
• Latex paint.  They are water based, and when they freeze, they get lumpy and lousy.  Your paint job will not be what you had in mind.
• Cellphones and computers.  Most of these have lithium ion batteries.  If they get colder than freezing (0 degrees C, 32 degrees F), if you try to charge them, you'll more than likely ruin the batteries. 
• Bottled water, soda, wine or beer.  OK, here's the scoop.  All of these can freeze and split the container they're in.  Yes, soda, wine and beer will take a lower temperature to freeze than water, but all of these can easily freeze if the mercury plunges low enough.  The problem isn't when they're frozen; it's when they unfreeze, drip out of their containers and leave you with a colossal mess. 
• Musical instruments.  Guitars are made of wood.  When a guitar freezes and you bring it quickly into a warm room, you may hear cracking sounds that tell you that guitar will be not-so-gently weeping from the damage that can occur.  The same goes for wind instruments and others.  Don't ever subject musical instruments to quick temperature extremes.

Take a little time and effort not to leave these things out in a frigid vehicle.  You'll likely spend far more time and money tending to the resulting consequences than if you'd just brought them inside in the first place.

Keeping Your Cool (Coolant leak repair)

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).  Or maybe yours has a picture of a thermometer on it and a blue and red zone.  If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does.

One of the most common causes of an engine running hot is a leak in your cooling system.  Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on.

Your vehicle’s coolant can leak for several reasons.  You may have hoses that are deteriorating (heat and age take their toll). It’s possible the pump that circulates coolant has developed a problem (seals and bearings can fail from heat and wear).  You may have something as simple as a bad radiator cap.  Or your radiator or heater core may have holes in it. 

If your coolant is leaking out, this can cause serious damage to your engine if you just let it go.  Your engine could get so hot that some of the metal parts start to warp.  Sometimes, your coolant can start mixing in with your engine oil.  That can result in a very expensive repair if it gets to that stage, so have it checked out before that happens.

A technician will visually inspect your coolant system, including the reservoir tank, check hoses and fittings, test the water pump, and also may pressure test the radiator.  When the problem or problems are found, they will replace the necessary parts and get you back on the road. 

When it comes to a coolant leak, finding the cause can be tricky.  But it’s important to catch a cooling system issue in time—before your engine sustains more serious damage.  Now, that’s pretty cool.

Don't Do It Yourself (Perils of DIY Vehicle Repair)

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies. 

Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s.

Today's most highly-trained technicians are able to keep up with how to perform the latest repairs and service by continuing education about their craft.  When once an auto repairman could do fine with a lift and a good set of tools, now specialized electronic analysis equipment and tools are must-haves when it comes to vehicle repair.

Because of how fast technology changes, access to the latest repair databases and manuals is also important.  Manufacturers require certain service procedures to be performed precisely, and any other way can leave a vehicle compromised when it comes to performance and safety. 

Your vehicle is capable of traveling at high speeds on challenging surfaces with ever-increasing traffic issues and unpredictable obstacles.  You need your vehicle to be working up to its engineered potential.  That's why you should leave repairs and service to professionals.  They work on vehicles every day, and years of experience with hundreds of repairs equip them to deal with the unexpected as well as the routine. 

When you develop a trusting relationship with a reputable service facility, you can have confidence that the maintenance, service and repairs are being done by people who know what they're doing.  Your safety and your vehicle's performance and reliability are well worth it.

Poor Reflections (Door Mirror Problems)

Mirror, mirror on the door, why is my vision there so poor? Well, you could have a broken outside rearview mirror that's disabled your blind spot vision there and endangering your ability to see some of the traffic around you. 

Outside rearview (or door) mirrors are important safety devices that are thoughtfully designed to help drivers see.  And there are a variety of ways those door mirrors can develop problems.

One is when the glass is broken in them.  Sometimes it's caused by an accident or vandalism.  But without your ability to see in that mirror, you could be driving blind, unable to see drivers approaching from the rear in adjacent lanes.  Sometimes it's as simple as having the glass replaced.  You'll greatly enhance your safety if you do.

Then there's the door mirror that you can't adjust.  First, let's look at a common scenario in later models, the power mirror.  They're great when they're working, awful when they're not.  Sometimes the motor fails, the switch goes bad or the wiring fails to deliver power.

Or how about the manually-adjusted door mirror that has either frozen up or just flops around? In this case, the mechanism has corroded, jammed up or a part has broken.  In both power- and manually-adjusted door mirrors, it sometimes can be hard to keep them in the right position.  Plus, every time there's a driver change, it may be hard to adjust those broken mechanisms by hand.

Finally, heated door mirrors can be extraordinarily useful in eliminating fogging or icing up in certain weather conditions.  But those heating elements can fail, switches can break or wiring can go bad.  Suddenly your fogged over, frozen mirrors aren't doing you any good at all. 

Good drivers use those outside rearview mirrors all the time.  They should be working the way designers intended, to provide the driver with vital traffic position information.  That's the kind of safety device you should get fixed or replaced sooner rather than later.  It's well worth it if you prevent even one little accident.
