No, summer heat in McHenry is harder on car, truck or SUV batteries than winter

There is a misconception that winter is more harmful to car, truck and SUV batteries than summer. It’s not true. Summer in McHenry is harder on automotive batteries than winter.

The reason for the misconception is simple. Winter thickens engine oil. This makes it far more difficult to crank an engine over and start your car, truck or SUV. The starter motor has to work harder to turn the crankshaft of the engine. That means that it is drawing more amps from the battery. If the battery isn’t up to the extra demand, the battery can let you down. And who wants their battery to let them down in the middle of a bitter-cold winter night?

In the summer, the heat is a battery killer. Think about it; some people store their AA and AAA batteries in the freezer at home. Doing so slows the self-discharge of the battery. The same principle applies outdoors with your car, truck or SUV battery. If it’s frigid cold outside, the battery is simply able to hold its charge longer.

Heat, on the other hand, shortens the life of a battery. It increases the chemical reaction that creates corrosion. The battery fluid can also evaporate faster. That fluid is essential to the health of a car, truck or SUV battery. Without it, the battery is damaged and its life is cut short.

In the heat, the battery works harder to produce the amperage needed to start the car. The additional strain in the winter is external. This means that your battery may have trouble keeping up next winter because of the strain the heat put on the battery this summer.

In any case, it’s a good idea to have your battery checked. Batteries do fail in the summer and yours could fail this summer if the heat has its way with your battery. Winter tests the strength of a battery. Summer attacks the strength of your battery.

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...

October 20 Hootenanny will benefit veterans with PTSD

Been to a Hootenanny lately? When you read that question did you ask, “What?” Well, if you have gone to a Hootenanny in a while, or if you don’t know what a hootenanny is, we have an event for Oct. 20 that will clear up either question. From 6 p.m. to Midnight, Saturday, Oct. 20, MC3, the McHenry Area Chamber of Commerce business networking group, is helping to host an inaugural Veterans R&R Wild Horse Hootenanny at Beyond Stable Farm (11129 Rte. 176, Woodstock). The event will benefit Veterans R&R Operation Wild Horse. Operation Wild Horse serves veterans with PTSD (Post-Traumatic Stress Disorder). Working with the horses has proven to have an incredibly calming effect on the veterans. And, it’s good for the horses, too, rescued wild mustangs. This means that the hootenanny is for a very good cause. But, it’s also a lot of fun. So, what is a hootenanny? According to a Google search, a hootenanny is “an informal gathering with folk music and sometimes dancing.” The V...
