Will a tune-up help my car this McHenry winter?

Winter in McHenry is a test for a car, truck or SUV. Parts undergo the extremes of severely cold temperatures. Rain, snow and ice assault the vehicle from all sides. If the charging system is weak, winter can provide the breaking point. On the other hand, this is one place where a tune-up can make a big difference.

Imagine that you are trying to start your pickup truck on a January night when the temperature in McHenry drops to 15-below zero. Let’s also suppose that your battery is several years old; it’s not as strong as it used to be.

When the temperature drops, the viscosity of your engine oil thickens. It’s harder for the starter to turn the engine so it can start. This is where a weak battery can leave you stranded on the side of the road. How does a tune-up play a role in this scenario?

With a tune-up, the car will run optimally. It will run better. It will start easier. So, if the battery is weak, and the SUV needs a tune-up, they may conspire to defy your wishes that the vehicle will start. On the other hand, if the car is running at its best – it doesn’t need a tune-up – it may start in spite of a weak battery and severe cold.

Does my car need a tune-up? That depends on the car, and how bad this winter is in McHenry. Older cars were designed with the expectation that they would receive a tune-up every 30,000-45,000 miles. Newer cars can go much farther between tune-ups. For instance, a new car may not need a tune-up until it has gone 100,000 miles since it was purchased, or between tune-ups.

Another way to answer the question – ‘Does my car need a tune-up?’ – is to consider how it is running. If the car is running rough, it lacks power, if the mileage has dropped recently (this could also represent a difference between winter and summer mileage), or it’s harder to start, the car may need a tune-up.

What can a tune-up include:

Spark plugs
Distributor cap
Ignition wires
Fuel filter
Air filter
Oxygen sensor
Adjust/Replace timing belt
Fuel injector/throttle body cleaning and service
PCV valve
EGR valve
Air pump
Check intake vacuum, compression, power balance
Adjust idle speed
Check vehicle codes
Check exhaust emissions

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...
