The Flat Fix that Fits (Tire Repairs)

Can you think of anyone who likes getting a flat tire?  Of course not.  But when one of your tires winds up with a flat or leak, whether it be from things like hitting a curb, running over a nail or picking up a sharp stone, it's time to have someone who knows what they're doing take care of it.

If you're thinking you'd like to avoid having to buy a new tire, you wonder if a patch or plug will suffice.  It depends where the puncture is and how big the hole is.  Most tire experts will say if the hole in the tire is less than ¼ of an inch or 6 mm, a patch can work.  But a patch likely won't work if the compromised part of the tire is on its shoulder or sidewall.

Here's why.  The shoulder of a tire is the part between the sidewall and tread and it's usually rounded.  It's under a lot of pressure, more than even the sidewalls. And because of that curved shape, it's hard to get a patch or plug to hold.

The sidewall is the side of the tire.  Sidewalls flex a lot when you drive, and the strain can cause a patch or plug to loosen up.  A weak spot in a sidewall is much more likely to fail and cause a blowout.  So if you have damage in the sidewall or shoulder, that tire is a good candidate for replacement, not repair.

If you have a cut or gash in your tire, it's possible the cords that strengthen your tire have also been cut.  That weak spot can spell trouble, and this type of damage usually means you should get a new one.

Your service advisor can tell you what the appropriate action is to take when you have tire damage.  You may be able to get good results with a patch, or you may have to replace one or more tires.  Your safety is riding on them.

The Sign of the Shield (Heat Shield Repair and Replacement)

Even in the months where temperatures are cooler, heat is still an enemy of your vehicle.  When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system.  Others prevent heat from reaching parts of the vehicle.  Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire. 

If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose.  If it had come off, his spacecraft could have burned up upon re-entry.  Fortunately, the heat shield stayed on, and Glenn made history.

Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.  So you have to maintain them.  Heat shields are constantly exposed to elements like water, salt, sand and dirt.  That makes them prone to rusting and corroding.  Here's one unfortunate fact: Materials that make them good at preventing heat transmission also are soft and vulnerable, often aluminum or special fabric. 

One sign a heat shield will give you that it's loose is noise; you'll sometimes hear it rattling underneath your vehicle when it's running. One way to locate it? Put your vehicle in park, leave the engine running and take a listen outside.  It's usually pretty easy to pinpoint the location.

Make a note of the noise when you are talking with your service advisor. It's important to have those heat shields working correctly so the heat is kept away from your other vehicle systems and combustibles on the ground. The good news is that heat shields can frequently be inexpensively repaired or re-attached.  In other cases, they should be replaced. 

Missing or loose heat shields? Let's just say they're not cool.

Objects in the Mirror (Rearview Mirror Safety and Maintenance)

You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving.

While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you.  There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors.

It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are.

Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, you'll never be sure they're pointed in the direction that will let you see where traffic is.  The one on the windshield must be firmly attached.  If it won't stay where you want it, head to your service facility where they can tighten it or replace any parts necessary to let the mirror maintain its aim. If it has fallen off the windshield completely, a technician can reattach it with the proper adhesives or fasteners.  There may be electronics that need to be properly connected as well.

The outside mirrors cover your blind spots and they must be able to hold their adjustments, too.  Many adjust electronically; switches and motors can fail, electrical connections can detach or become corroded and the reflective glass can crack, discolor or develop a hazy fog.  A technician can diagnose and repair those problems and recommend any replacement parts you might need.  Mirrors that are adjusted manually also should be restored to proper working order in order for you to maintain this important rear visibility.

Drivers don't think about their rearview mirrors all that much.  On reflection, don't they deserve respect and care for the important job they do?

In a Fog (Fogged Windows in Cold Weather)

It's bad enough in cold weather when ice and snow block your visibility.  Add to that fog on the inside of your windows and you could be driving blind.  So here are a few tips on how to keep your windows from fogging up when there's a chill in the air.

You probably know fog is really condensation, when moist, warm air meets a cold surface and turns to liquid.  If your windshield fogs up, you probably turn on your windshield defroster. Most defrosters blow heated air on the windshield glass to warm it up so it won't condense the moisture.  Many also turn on the air conditioning to reduce the moisture. 

That same strategy can work on the rest of the windows.  First, turn up your heater's temperature setting.  The hotter the air, the more moisture it will hold.  Also, turn off the "recirculating" setting since you want all outside air to come in. Then switch on the air conditioning.  It will remove the moisture from the outside  air that it's blowing inside the cabin.  Try cracking a couple of windows to make it easier for the air to flow. This should do the trick pretty quickly. 

There's one other thing to try.  Many vehicles have electric heater elements embedded in the rear window glass (the rear window defroster) and in the outside rearview mirror glass. Make sure to turn those on, too; sometimes they're on the same switch.

For all of these things to work, of course, your vehicle's components have to be maintained so they'll do the things they're designed to do.  And you didn't think it was important to have your air conditioning working in the cold weather months! 

One final tip.  Keep the insides of your windows CLEAN.  Oil and dirt on the glass give the water molecules something to latch on to.  That ought to clear up this problem.
