SOUTH BRUNSWICK - The escalating heat is not only affecting New Jerseyans, but its taking its toll on their cars too.

Experts say extreme heat can be worse for cars than bitter cold.

AAA fleet operator Pete Sommers says he has been rescuing drivers with overheated cars. Sommers says about 80 percent of the calls are related to car batteries. "The batteries have extra fluid in them," Sommers says, "and extreme heat degrades the plates in the batteries." He says most only last three to four years.

Sommers suggests that drivers check to make sure their air conditioning is working efficiently. Drivers should also keep an eye on fluid levels and check hoses and belts for wear.

AAA also recommends pulling off the road, shutting off the engine, and calling for help if your car overheats.
