Winterizing Tip # 4: Make sure the car, truck or SUV will start this McHenry winter

It’s comforting to know that, no matter how cold it is outside this McHenry winter, when you run out to your vehicle, your car, truck or SUV will start. When you have that kind of comfort, you don’t even think about it. It’s subliminal. But if you don’t have that confidence …

If there is a weakness in your car, truck or SUV charging and starting system, a McHenry winter is likely to find it. There are a number of issues that could give your vehicle trouble starting when the temperature drops.

The charging system: The charging system recharges the battery and operates the electrical systems while your car, truck or SUV is running. If it doesn’t provide enough electricity, such as with an alternator that isn’t up to speed, the battery will slowly lose its charge while the charging system will fall short of providing the energy required to keep the vehicle running. Either the vehicle won’t start one day or you’ll find yourself stranded on the road somewhere.
The battery: The battery is a diminishing component; over time, it will fail by losing its ability to hold a charge. But, thankfully, the battery should keep your car, truck or SUV starting for several years before you need to worry too seriously about that. As it gets older, and loses the ability to hold a charge, it will find it increasingly difficult to provide the amps needed to turn the engine. This problem is increased in the cold when the engine oil is thicker.
The starter: The starter is connected to the electrical system and has a gear that turns a gear connected to the engine. The starter requires a certain amount of amperage in order to do its job. While an insufficient charge in the battery will cause problems, a starter that wears out and requires additional amperage to operate is liable to cause the same problem.
Connectors and wires: If the wires and connectors that keep the amperage traveling through your electrical system aren’t clean and in good condition, you can have problems there, too. One of the common places to find a problem with electrical connectors is at the batter. Cleaning connectors can make the difference between a vehicle that will start and one that won’t.
Belts: Most cars, trucks and SUVs today have a serpentine belt. But, whether your car has a serpentine belt or an older-style ‘V’ belt, something needs to turn the pulley on the front of your alternator. If it stops turning, the alternator will put out precisely zero amps and your vehicle will quickly come to a halt.

Winterizing your starting and charging system means checking that all of these components are in good condition and performing their jobs as intended. If everything is in tip-top shape, you have no worries. But at least you’ll know. If something is wrong, you can either figure it out ahead of time or wait for winter cold to point it out for you.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
