Now that your coolant is keeping the engine cool, what about AC for you this McHenry summer?

Last week, this blog focused on keeping your vehicle’s engine running cool this coming McHenry summer. That’s important. Ensuring that your vehicle’s cooling system is up to snuff, and the coolant will do its job, are essential to protecting your vehicle from the effects of summer heat. It will also help you avoid the expense and inconvenience that comes with getting stuck on the side of the road. But what about keeping you cool?

Keeping yourself cool as you drive about McHenry, or from McHenry to other destinations, is a matter of comfort. But it’s also a matter of safety for those who are elderly or otherwise infirm. Your vehicle’s air conditioning takes a hot box interior and creates in its place an environment that puts the passengers at ease regardless of the temperature outside.

Whether your vehicle’s AC will actually do the job, regardless of the temperature outside, depends on the condition of that air conditioning system in the vehicle. Are all the parts in good working order? Is the AC system fully charged? These are essential questions.

A car with air conditioning that is not fully charged may work well enough on a day when it’s 72-degrees outside. But what happens when the outside air hits 95 degrees. A system that works fine at 72 may fail to keep up at 82 degrees. At 99 degrees, that system may blow nothing but hot air out of the vents.

Fully charged, if all the components work properly, your vehicle’s AC system should keep you cool inside the car even if it’s 102 outside. To the extent that it’s not fully charged, is the extent to which you can count on your vehicle’s air conditioning to fall short – the degree to which you’ll be hot while driving your car.

The other aspect of the issue is the operation of the components of your vehicle’s air conditioning. If a part is broken, if a compressor doesn’t do its job or the belt that turns the pulley on the compressor is liable to break, you could be as hot inside the car as though your system had no charge at all.

The AC in your vehicle needs to have a dryer that dries properly. The expansion valve needs to work as designed. The coils need to be clear. The evaporator and blower need to work in unison with the rest of the system to keep that cool air flowing into the cabin of your vehicle. If the coolant lines leak, you’ll soon find yourself short of coolant.

Fortunately, air conditioning systems in vehicles are fairly reliable. Usually, all you need is to have them checked and have the system recharged. We will have hot days in McHenry this summer. Having your air conditioning checked will ensure that you can take all that summer has to offer without breaking into a sweat.

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...
