With summer just around the corner, it's not too early to begin thinking about hot weather driving and even that long-awaited vacation trip with the family. Whether you will drive cross-country or merely across town, it makes sense to take a few minutes now to assess the condition of your car or truck. A mechanical breakdown in the middle of nowhere is no fun regardless of the time of year, and in some cases can be downright dangerous. Taking the time now to check the condition of your vehicle could be the difference between a hassle-free trip and the vacation from, well... a very hot location.
Windshield Safety
If your windshield has a rock chip or ding at winters end, that damage needs to be repaired before thermal shock causes the minor ding to turn into a major crack. Thermal shock can occur when cold air from the air conditioning blows directly on a windshield that is scalding hot from exposure to the summer sun.
Fluids
Checking fluids is the least expensive and most important preventive maintenance you can do. Oil should be changed frequently (every 3,000 to 5,000 miles) if you haul heavy loads or drive in stop-and-go traffic. Remember to flush your radiator and change your engine coolant every two years. Summer is extremely hard on a cars cooling system, so inspect your radiator for obvious signs of corrosion or leaking. If in doubt, have your mechanic check the radiator core to ensure it is not plugged or at risk of imminent failure. Make sure you also check and fill to recommended levels other fluids integral to your vehicles performance. These fluids include: power steering, transmission, brake, radiator and battery. Don't forget to top off windshield washer fluid. Every driver knows the importance of windshield washer fluid but sometimes we forget to check until we need it most & and then it's too late.
Batteries and Corroded Cables
Summer heat can wreak havoc on an older battery. The average life of a battery is 3 1/2 years. If your battery is nearing that age or is older, than it's probably ready to be replaced. Have a mechanic check the battery and cables to ensure your car starts quickly and reliably.
Anything Made of Rubber
Worn, bald or badly aligned or balanced tires can mean accidents. Be sure to check your owners manual for the recommended tire pressure, too. Tire pressure is critical in summer, especially when carrying heavy loads. Tire pressure should be checked and air added when the tires are cold (driven a short distance). Remember, tire pressure increases one pound for every 10-degree increase in temperature. If you inflate your tires to the maximum pressure indicated on the tire sidewall, you risk tire failure from over-inflation, especially if the tire is worn or damaged. If traveling in remote areas, it may even be wise to carry a full-size spare tire instead of a temporary emergency spare, or donut, as they are sometimes called. Temporary emergency spares usually have a 50-to- 100 mile life expectancy, which may be inadequate for long trips. Rubber parts under your hood need maintenance, too. Radiator, heater and vacuum hoses, among others, should be checked for cracks and bulges. Take a roll of duct tape with you on your trip; it can be a life saver in fixing hoses. Also, inspect all belts for damage and splits.
Spark Plugs
Worn or misfiring spark plugs can affect how efficiently a vehicle burns the fuel/air mixture, ultimately affecting engine performance. Worn spark plugs waste gas and increase exhaust emissions, so have them checked and replaced as needed.
Brakes
Don't postpone needed brake work. It's dangerous to drive with poorly performing brakes. Postponing brake service also can cause the cost of overhauling your brake system to skyrocket.
Lights
Check your lights and turn signals for safety's sake.
Be Prepared
Before you leave on your trip be sure to pack extra radiator coolant, several quarts of oil, safety flares and whatever tools you might need. It is better to be prepared than sorry. If properly maintained, your vehicle will provide years of service with better performance and safety.
