Is Your Vehicle Ready to Handle the HeatOh, the horror! On a brutally steamy summer day, you leave the cool confines of your workplace and make the long, sweltering walk across a shoe-meltingly hot parking lot. You open your car door and the blast of heat that emanates forth nearly knocks you out. You pause for a moment and contemplate just how toasty your seat is, not to mention your steering wheel. With a bit of trepidation, you take the plunge and inch into the vehicle. Hot! Hot! Hot! No worries, though. You know your air conditioner will kick in in no time. You crack your window to allow the heat an escape route and wait. And wait. 

You hold your hand near the air vent questioningly as sweat starts to form on your brow. Why isn’t there cool air flowing? You turn some knobs and flick some switches, and still nothing. The slowly awakening horror is suddenly upon you. THE A/C IS BROKEN!!! 

Is this an unavoidable cosmic joke, or could you have taken some preventative measures to help assure this didn’t happen? Jim Ward, Service Manager at Smart Motors in Madison, says there are many steps one can take to avoid such a sticky situation.  

“Wisconsinites know how important it is to winterize their vehicles, but often they neglect to ‘summerize’ them, too,” Ward says. “While some things can easily be done by the owner, there are also somewhere a service professional comes in handy.” 

Ward says it is wise to have a service technician thoroughly inspect your vehicle’s HVAC (heating, ventilating, and air conditioning) system at least once a year. Often you can request this service in conjunction with another service such as an oil change. Typical A/C service consists of the following steps: 

  • A visual inspection of hoses, lines, seals, and other components for leaks as well as inspecting the drive belt for cracks or damage. 
  • check of pressures to test operation, refrigerant charge, and outlet temperatures. 
  • If the system is found to be low on refrigerant, a leak test is performed to find the source of the leak. Keep in mind that if your vehicle is leaking refrigerant, it is damaging the ozone layer. 
  • A/C service should also include a check of the compressor’s drive belt and tension. 

These measures should be enough to get you comfortably through the heat, but Ward says his team is trained to offer additional measures that will help your car stave off the heat of the street. Additional procedures that either the vehicle owner or service technician can perform are 

  • Check the level and strength of the coolant. A low coolant level may allow your engine to overheat. Make sure the coolant reservoir is filled to the proper level. Wait until the engine has cooled to check the level inside the radiator. If low, add a 50/50 mixture of the specified coolant and water.  
  • Make sure the cooling fan works. The electric cooling fan should come on when the air conditioner is turned on to MAX. No fan may mean a defective fan motor, relay, or electrical problem.  
  • Battery evaluationBatteries are lasting longer than they used to but the key with a battery evaluation is in the testing which gives both the available cold-cranking amps vs. what the battery is rated for and the second is a battery health check which indicates potential battery life and can often predict a battery failure before there are symptoms. Hot weather is actually harder on batteries than cold weather because it increases the rate of evaporation of the liquielectrolyte inside the battery. 
  • Change the oil. Replacing old dirty oil with fresh oil can increase the lubrication protection for your engine.  
  • Check or replace the windshield wipers. Natural rubber wiper blades have a limited life of a year or less. Sun exposure, extreme heat, and cold all age the rubber and cause it to become hard and brittle.  
  • Check tires. Check the tire for wear, uneven wear, age cracks, or damage. Check the inflation pressure in all the tires, including the spare. Underinflated tires make the tires run hot and increase the risk of a blowout.  

Lastly, Ward says there are a few steps that vehicle owners can do themselves to stay cool:  

  • Wax the body. Your vehicle’s body should be waxed or sprayed with some type of protectant to help shield the paint from the ultraviolet rays from the sun, and summer smog in urban areas.  
  • Keep your cool. Buy a sunshade for the windshield to reflect light so the interior doesn’t get so hot if the vehicle is parked in direct sunlight. Also, close the sunroof sunshade, and leave the windows cracked so hot air can escape. This can lighten the cooling load on the air conditioner when the vehicle is first started, and prevent you from getting a hot seat or burning yourself on hot interior surfaces. 
  • Protect yourself. Wear a hat and sunscreen, and carry a bottle of water in the car in case you get stuck for a long period of time in traffic or have a break-down on a hot day. 

Ward says these precautions should be enough to keep you and your vehicle cool. Of course, bad things happen at the absolute worst time, but taking some simple preventative measures should drastically lower the risk of them happening to you.
