Prep for Summer Heat with a Chevy Service Appointment

Iowa summers don't ease into it. The heat comes fast, the humidity follows, and your Chevrolet vehicle ends up working harder in June and July than it does the rest of the year. Booking a Chevy service appointment at Vaughn Chevrolet of Ottumwa before the season peaks is the best way to make sure everything holds up when the temperature starts to climb. Air Conditioning If your A/C is blowing warm or taking longer than usual to cool the cab down, you want to get it addressed before summer hits full stride. A service visit covers the three areas most A/C problems start: refrigerant level, compressor function, and cabin air filter condition. Cooling System Your engine works harder in sustained heat, and a cooling system that's low on coolant or dealing with a weak hose won't give you much warning before it's a problem. Getting your coolant levels, hose condition, and the radiator checked now is cheaper and a whole lot faster than dealing with an overheating situation on the road. Battery The heat is just as hard on batteries as cold weather, if not harder. If your battery is three or more years old, a load test during your service visit takes about five minutes and tells you whether it's ready for another Iowa summer or due for a replacement. Tires High temperatures cause tire pressure to rise. Overinflated tires wear unevenly and reduce traction in wet conditions. A quick pressure check and tire inspection ensures you won’t have your summer fun interrupted by a blowout. Schedule Your Chevy Service Appointment in Ottumwa, IA Your Chevrolet vehicle was built to handle whatever you put it through. A summer service visit at Vaughn Chevrolet of Ottumwa makes sure it stays that way. Schedule your Chevy service appointment online or give us a call.
