Hot enough for you?
Oh, sorry not you. I was talking to your car.
All due respect to your human suffering, but your trusty vehicle — the one you rely on to take you to work, on vacation and off to holiday weekend day-tripping destinations — can’t just drop its top and jump into the lake at Hippie Hollow when the thermometer hits triple digits (unless, I guess, it’s a convertible and you have really good insurance).
The prolonged hot weather we’ve been having is hard on vehicles, but a little preventive maintenance can go a long way toward ensuring that you don’t wind up stranded on the side of the road withering in the heat while waiting for a tow truck.
Cars are complicated beasts and, of course, anything can go wrong at any time. But experts say there are four main problem areas that crop up as the mercury rises: batteries, tires, radiators and air conditioners.
I know firsthand about the battery issues. A few weeks ago I was leaving a coffee shop where I’d been writing a story. When I hopped in my car and turned the key, it didn’t make a sound. It wouldn’t take a jump. I had to schlep it to the auto parts store and drop $100 on a new battery.
“The extreme heat makes the acid and the fluid inside of them (car batteries) expand, which can cause them to start leaking,” says Jim Kilgo, a supervisor at Austin’s Groovy Automotive and Groovy Lube. “That causes battery failure in the long run.”
Sarah Schimmer, AAA Texas public affairs representative, recommends that drivers keep in mind the age of their vehicles’ batteries, especially in hot weather. “If it’s older than 2 to 3 years, have it tested and consider having it changed out,” she suggests.
I haven’t blown any tires this summer, but I saw enough of them on the highway during a recent road trip to Florida that I have come to believe split treads should be the official state roadkill (reauxdkill?) of Louisiana.
Heat raises tire pressure, which is why manufacturers recommend checking their inflation before driving. And worn treads compound the effect. “As you drive during any month of the year, your tires’ PSI (pounds per square inch) will raise from 5 to 8 pounds,” Kilgo explains. “When it gets hot like this, it’s going to raise even more. If you’ve got weak tires — worn tires — you’ve got a better chance of having a blowout.”
Here’s a bonus: Properly inflated tires in good condition (don’t forget your spare) will improve your gas mileage.
If you see a car stranded on the shoulder and it’s not up on a jack, chances are it has overheated. Your car is already working harder than normal in extreme heat, and low coolant levels can spell disaster for its engine. Belts stretch and hoses deteriorate with age; long periods of extreme heat can accelerate the process.
“A hose failure can cause an engine to blow almost before you can shut it down in this heat,” Kilgo says.
“If you’ve got worn hoses that haven’t been replaced in a while, you’ve got a better chance of a hose rupturing now than you do at any other time.”
Steve Pustelnyk, director of communications for the Central Texas Regional Mobility Authority, recommends a simple hose, belt and coolant level check. “Don’t overheat the engine through a lack of fluid, and don’t have a hose fail and lose all of your coolant,” he says.
You’ll also want to have your mechanic check your air conditioner to make sure it’s working properly. In extreme heat, drivers tend to run the AC continuously, often at full blast, which puts extra strain on the cooling system.
Finally, Schimmer points out that every vehicle has a useful preventive maintenance tool factory-installed in the glove compartment.
“Basically, every car comes with an owner’s manual, and in the owner’s manual there’s a severe driving section. It’s a maintenance schedule for severe driving conditions,” she says.
And that information is especially valuable to Austinites, she notes.
“Those include long commutes, extreme weather, dusty, unpaved roads — that’s basically a Texan’s every day.”

If you’re stranded …
But what if your vehicle does fail? What if you’re one of the countless Americans who disregard maintenance schedules and prefer to deal with problems as they crop up?
The Central Texas Regional Mobility Authority runs the Highway Emergency Response Operator Program, which provides aid to stranded motorists on Interstate 35. From 6 a.m. to 8 p.m. Monday through Friday, HERO vehicles patrol a 35-mile stretch of the interstate from the Hays/Travis County line to U.S. 79 in Round Rock. HERO personnel can change tires, jump batteries and add gas and water to vehicles. In addition, they’ll help you to move your vehicle off the road so that traffic doesn’t back up.
Stranded motorists can call 974-HERO (4376) for assistance.
AAA’s Schimmer offers some additional tips on what to do if your car breaks down:
Keep some cash in your car, in case you run into a situation where credit cards are not accepted.
In spite of high gas prices, don’t let your car run on empty.
Keep an extra quart of oil and a gallon of water in your trunk.
Make sure your cell phone is charged in case you’re stranded in an area where you can’t walk for help.
Be aware of your location — noting landmarks, etc. — so that you can be found if you need to call for assistance.
If you’re on the highway, pull off to the side of the road if you can and secure the safety of yourself and your passengers. Make sure your vehicle is visible. If your car dies just over a hill, for example, other automobiles coming up that hill won’t be able to see you.
