Is your car, truck or SUV’s heater fading as this Johnsburg winter progresses?

You may find this Johnsburg winter feeling

chillier and chillier if your car, truck or SUV
heater is failing.

On those chilly Johnsburg nights in December, it took no time at all for the heater in your car, truck or SUV to start pumping out some hot air to keep you warm. But now, we’re halfway through January and you’re beginning to notice that it takes longer for the heater to catch up. And then it never quite gets as hot as it used to.

Possibly, this has something to do with winter temperatures in Johnsburg falling colder and colder. The colder it gets outside, the harder the heater has to work to provide that comfort-giving heat you’re counting on. But that’s not a certain answer to the question.

It’s also possible that, though your heater was working in peak performance when winter started, it may not be working at the same efficient level now. Why would that be?

If your car, truck or SUV’s heater is losing its mojo, it almost certainly has something to do with one of the following:

The level of your antifreeze. If the antifreeze level has fallen, there are times when only air is passing through the heater core. The fan inside your car, truck or SUV’s cabin isn’t going to draw heat from an empty heater core. And if the level of your antifreeze has fallen, there’s a good chance that you’ve got a leak somewhere. You’ll need to fix that before you fill the radiator again.
The heater core is clogged or leaking. If the heater core is leaking, you may have antifreeze dripping onto the floor of your vehicle. If it’s clogged, hot antifreeze can’t get through and, once again, the fan has no heat to pull into the cabin.
Speaking of leaks, the radiator, a radiator hose, a heater hose, a gasket or something even more concerning, my be leaking. Once again, you’ll need to fix that leak to get back in business.
The thermostat is on the fritz. The thermostat shuts off the flow of antifreeze into the engine at certain temperatures thereby allowing the antifreeze inside the engine to heat up. If the thermostat is stuck open, the antifreeze may have difficulty reaching the temperature that will provide the heat you want inside the car, truck or SUV.
The water pump isn’t working. The water pump pushes the antifreeze though the engine, through the hoses, through the radiator and through the heater core. Usually, if the water pump fails, you’ll find that it’s leaking, too.

If you prudently had your antifreeze and cooling system (the cooling system is the same system that provides hot antifreeze for your heater core) checked in the fall, there’s a good chance you’ll make it through the Johnsburg winter of 2024-25 without a problem. But, if you didn’t winterize this part of your vehicle, a problem may have sprung to life as the winter progressed.

Even if you did have you antifreeze and cooling system checked, it’s not an absolute guarantee that you won’t have a problem. It’s less likely but possible.

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...
