Just like the bitter cold, extreme heat can cause problems with your vehicle. Keeping an eye on certain parts of your car, like the tires, is needed this time of year.

“The tires are very important during the summertime because of the roads and how hot they are and the rubber compound’s already hot, so rotations are very important,” says Lee Smith, the service manager for Johnson Dodge Chrysler Jeep in Meridian. “Your performance tires tend to wear faster; if you have a performance car, watch your tires real good. The newer tires with the heavier compounds will last 50,000 to 75,000 miles but you have to keep them balanced and have to keep them rotated every 5,000 miles at least.”

Making sure your engine remains as cool as possible in the heat of the summer.

“Biggest thing is to watch is your coolant, never check it hot of course, because it will blow up on you, that stuff is boiling in there,” Smith says. “So your radiators, check them, make sure that there’s no dirt in there, a lot of times we’ll have people come in that have run through dirt roads, behind somebody and they’ll just get clogged up, and it will get your motor.”

Air filters must also be clean, especially when it gets hot outside.

“A dirty air filter will cause an engine to run hotter because it’s not getting as much cool air,” Smith explains. “Bad spark plugs, not being maintained will make it run hotter because it’s burning more fuel.”

Last but not least, make sure to use your air conditioner efficiently.

“You have a re-circulation button in there, and that’s a little button that’s got a little ‘U’ on it with your air conditioner and that’s where it’s recirculating the inside cool air, and it’ll make your air conditioner a lot cooler,” Smith says.
