What the Michigan Heat Does to Your Car

2019 Michigan Summer Collision RepairSummer is here and it’s road trip season! That means it’s time to get your car checked out from top to bottom—the heat of the season can have adverse effects on your car, and breakdowns are something you definitely don’t want when you’re out on the road and miles from the nearest gas station.

Sometimes we get wrapped up in maintaining our car during winter, as it’s commonly seen to be the toughest season for our vehicles. While that may be true, you simply can’t neglect your car’s upkeep in the summer. You’re much more likely to get tire punctures when it’s hot, and clutch problems are more common with the summer heat causing additional wear and tear.

Today we’ll be taking a look at what happens when your car is exposed to extreme heat during the summer months.


While lower temperatures during the winter can be detrimental to the condition of your car’s battery, the high temperatures of summer can take a toll as well. Extreme temperatures can hinder the chemical processes inside a car battery, meaning they struggle to hold charge and produce enough power for your vehicle.

Now, add in the fact that you’ll likely be running the air conditioning at full blast and the load of all your electrical systems powering the windows, convertible roofs, and so on and so forth, and you’ll see that your battery may not be up to the task during a long hot summer.

Wheels and tires

Car tires absolutely hate high temperatures. A high external temperature means the air inside the tire will expand, causing over-inflation and possible damage to the tire. Even if your tires were in perfect condition in the spring, making sure that they’re still at an acceptable pressure in the summer is going to be very important.

Car cooling system

Your engine actually needs to be at the correct temperature to operate properly. Extreme outside temperatures, both high and low, can make it difficult for this to happen. The car’s cooling system uses a coolant to keep parts of your engine cool enough to run without issues. When it’s extremely hot, this coolant will be at a higher temperature than normal, meaning it can’t cool the engine as efficiently. This can cause parts of your engine to overheat and fail. Most of the time this can happen when you’re driving at lower speeds as there isn’t enough airflow to pick up the slack—going faster means more air runs through the engine and radiator, and then carries away excess heat.

Air conditioning

On the subject of cooling, even us humans need to be kept cool—that’s where your AC comes in. While you may not have used it much or at all during the winter and spring, that doesn’t mean it didn’t experience wear and tear over the course of those seasons. An air conditioning unit is a particularly finicky piece of equipment, and even small leaks and degradation in the tubing, condenser, or radiator can mean that you’re sweating through your road trip instead of driving on in cool comfort.

All these issues can be prevented with a proper maintenance schedule. Just because it’s summer doesn’t mean we can slack off with keeping our vehicles in top condition! Failing to prepare means you can be at risk for accidents when you’re supposed to be relaxing on your vacation. You can check on a lot of these possible issues yourself, but of course, the best way to prevent accidents is to have professionals regularly check your vehicle.
