Too Hot to Handle (Vehicle Overheating)

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road.

Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking). 

When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine. 

If you can do it safely, pull off the road to a spot away from traffic.  Turn off the engine so it can cool down for a few minutes.  You may want to call for help at this point, then switch on the key to "accessory" position to see if the engine has cooled down to the normal range.  You may have to have your car towed to a service facility or, if there's one nearby, you may be able to slowly drive to it.  But keep your eye on the heat gauge and immediately stop if it starts to overheat again. 

The best hedge against engine overheating is regular maintenance.  When the cooling system and other engine components are working like they should, your chances of an overheated engine are drastically reduced.  Your service facility will keep their eyes open for leaking hoses, cracked belts, rusted pipes and other things so they don't fail at the most inopportune time.

An Oil for All Seasons (Engine Oil Selection)

You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may seem like it makes sense, there's some good news.  Most drivers don't have to, and here's why.

Engine oil can be made in different thicknesses.  That thickness is called viscosity, how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather. 

While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now that's what I call a great invention.

In most temperate climates, you don't have to swap out the type of oil you use in your vehicle each season. There are exceptions in extreme climates, but your service advisor can advise you on that.  Your vehicle's owner's manual recommends the proper viscosity oil to use.

Remember that even though you may not have to switch to a different type of oil, you DO have to CHANGE the oil at certain intervals.  That's because oil eventually breaks down and picks up contaminants, and if you have old, dirty oil in your engine, it can cause damaging friction and heat. Regular maintenance at your vehicle service facility will ensure that your vehicle is running like a well-oiled machine.

Pinch Petroleum Pennies! (Fuel Saving Tips)

If you saw a dollar bill on the ground, you'd pick it up, right? Well, whether you find that dollar on the ground or in savings at the gas pump, money is money, and here are some ways to hold on to more of it.

Slowing down is the easiest way to save fuel, especially for every speed increase over 50 mph/80 k/hr.  Tone down the speed, turn up the cash savings.  Drive smoothly (not like a race car driver) and you'll also save money in fuel.  Aggressive, fast-start, jerky-stop habits are just pulling the bucks out of your wallet about a third more than if you drove just a little more gently.  Oh, and cruise control can help with that smooth, steady speed, so use it on the highway. Bonus!

Are you hauling around a set of dumbbells or a box of books? That extra weight is costing you dough.  Store them somewhere else.  When's the last time you checked to see your tires were inflated properly? That's another money saver and makes your vehicle safer.

An idle thought… don't idle any longer than you have to.  If you will be idling for more than 30 seconds you'll save money by turning off the engine and re-starting it.  More and more of the latest vehicles now do this automatically.

Some like it cold.  But air conditioning uses a lot of extra fuel.  If you can live with the cabin at 72 on a hot day rather than turned down to arctic freeze levels, you'll save some cool cash.  Turn off the A/C all together can save you from 5-20 percent

The key to a fuel-efficient vehicle is keeping it well maintained.  If your spark plugs are old, your belts frayed and your brake pads worn, you're just throwing away fuel.  Try a few of these gas-saving suggestions and while you're at it, you'll be helping to reduce your carbon footprint that will help everyone on Planet Earth.

QUIET TIME (Listening for Vehicle Problems)

Everybody's got friends like this.  You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening.  They just love to hear that music, sports, news… anything but the sound of the vehicle itself.

And maybe you're that person, too.  Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things:

• A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out.
• Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octane gasoline than is recommended for your engine.  Time to get that checked out.
• A squealing or high-pitched sound coming from the engine compartment. Could be a belt is loose, wearing out, dried out or cracked. A pulley might be failing or a bearing might be on its last legs.  Better to have that fixed now than be stranded somewhere later.

Here’s our Arizona Auto and Radiator Repair suggestion - set a regular weekly alarm in your smartphone alerting you to listen to your vehicle once a week for five minutes.  Just five minutes without the music or the sports show or public radio… whatever your taste is. You can even use your smartphone to record any noise you might be hearing.  Between that and your description to your service advisor, a Arizona Auto and Radiator Repair technician should be able to diagnose the source of the noise and get your vehicle sounding healthy again. Do it before that noise turns into the sound of a serious problem. 

Who knew a little quiet time could be so useful?

No Yolk! Rotten Egg Smell (Sulfur Smell Causes)

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up. 

If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe.

There's another possibility, but it's usually only in stick shift vehicles.  That's leaking, old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance.  Once the cause is found, repairs made and/or parts replaced, the smell should go away fairly rapidly.
