PADUCAH — The owner of a local service station tells us higher temps mean more customers but one very common problem might surprise you.

It has to do with what's going on under the hood.

We know tire blow-outs are common during extreme heat but drivers are also dealing with bad batteries and cars that just won't start.

Typically, we associate that with winter weather but a mechanic told Local 6 temps like these can be even more destructive to your car.

Making matters worse is all the in-car technology we've become accustomed to.

Some cars just can't take the heat, so they end up in places like Shelby's Wheel and Tire.

Owner Joe Goff said even the toughest technicians are getting tired. It's all because of the heat.

"It's hard working on the cars, because pull them into the shop and they're all like furnaces just putting out 400 degrees or something," he said. "You get four or five of them side by side in a small shop, it really heats things up."

The more the mechanics work in this small space, the hotter it gets and the harder the job becomes.

Goff said the same thing happens under the hood.

"The hood's just stuffed with everything," he said. "They're like furnaces underneath the hood of the car."

With today's technology demanding more from batteries, many just stop working.

Before you hit the road this holiday, Goff said you need to check a few things: your battery, fluids, tires and tire pressure. Better to check these things now than to end up stranded on the roadside later.

Goff said many don't think about their battery in the summer but they should.

"Heat and all the demand on them, it's just tough and they'll give up after a while."

Giving up is something the mechanics can't do because customers are waiting and in temps like these, business is booming.

One of our Facebook fans asked if batteries still require water. Goff said some of them do. In fact, you should check the water level frequently, especially during these hot temps. Make sure you add distilled water when needed.

A typical car battery lasts anywhere from three to five years.
