Get Your Vehicle Road-Ready If you’re taking the family truckster, it’s wise to get it serviced before you hit the road. An oil change and a tune-up are great places to begin. Make sure your AC is fully charged if you’re heading someplace hot. Get your coolant system checked too, as an overheated engine will stop you dead in you tracks. If your ride does start to overheat, turn off your AC, open your windows, and turn on the heat. Yes, you’ll feel like you’re in an oven, but your car’s heater pulls heat from the engine. Keep an eye on the temperature gauge, and if the needle starts to drop, you might be able to make it a few more miles to a service station.
