Are you stuck in a McHenry parking lot because your battery terminals are dirty or corroded?

The car won’t start and there are multiple explanations for why it has left you stranded in the parking lot of this McHenry shopping center. The battery could be bad. The alternator could have run its course. The serpentine belt that drives the pulley on the alternator could have broken. These are all plausible explanations. You could even have some other deeper electrical problem, though that’s less common. But, the problem could be simpler than all this.

It’s possible that your battery terminals are dirty.

The connection between the cables that run from the battery to the charging/starting system on your car, truck or SUV is crucial. Just think about it; if you disconnect a battery cable the car definitely will-not start. But, what if the terminal is connected but corrosion has won the battle and the electrical current can’t get through?

Sometimes, you’ll see a battery terminal covered with a white powder. This is a definite sign that corrosion is winning at the expense of the electrical current. Even if it’s still working, it’s not working as efficiently.

The corrosion is caused by hydrogen gas released by the battery mixing with the elements. Overtime, it will work its way between the terminal and the connector until the electricity can’t get through. But, the corrosion doesn’t always have to be that evident.

There are times when the terminal looks good, maybe a little grey, but generally clean. Why would you expect to have a problem with the terminal connection? But, it’s quite possible.

If the car won’t start, you can call a tow service to come out to the McHenry parking lot and give your car a jump. But, if it didn’t start once, it may not start the next time. Anytime your car won’t start, it’s a very good idea to figure out why so that it doesn’t happen again.

Since corroded terminals can be the culprit, even if they look clean, it’s not a bad idea to clean your terminals. There are inexpensive wire-brush tools you can use to clean the terminals. Or, you can ask your auto repair shop to clean them the next time you’re in for an oil change or some other service.

If the terminals aren’t the problem – you do have a good connection, then it’s time to start looking at other possible problems. How old is the battery? How old is the alternator? Do you still have a serpentine belt?

Take care of these issues, and keep your terminals clean, and you probably won’t find yourself in a McHenry parking lot, or any other parking lot, with a car that won’t start.

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...

Timely maintenance is even more important with your Johnsburg Electric Vehicle

Even if you have an electric vehicle in your Johnsburg driveway, maintenance is still critical. You pull out of your Johnsburg driveway and you watch the gas stations go by as you smile from behind the wheel of your EV – Electric Vehicle. Of course, at some point, you will have to stop and charge the battery but you still take some comfort that you’re not standing next to your car as the fuel pumps into your tank. One of the true comforts you take with your EV is that the mechanics of your vehicle are simplified. You don’t have to worry about the engine breaking down anymore, and we all know how costly that can be. But there’s more to your EV vehicle than you may have considered when you first parked it in your Johnsburg driveway. Many of the parts found on gasoline-driven vehicles are also present on your EV. These require the same maintenance as your gasoline-powered vehicle. For instance, you EV still has: Tires and Wheels Brakes Steering and Suspension Windshield Wipers and So...
