Summer brings sun, fun and increased recreational driving. Be certain your vehicle is ready for warm weather:
Check the level and strength of the coolant.
A low coolant level may allow your engine to overheat.
Check the air conditioner.
Make certain the air conditioner blows cold air. If not, the refrigerant charge may be low. Check the system for leaks before adding refrigerant.
Check the age of your battery.
Most car batteries last 4 or 5 years. Hot weather is actually harder on batteries than cold because it increases the evaporation of liquid electrolyte inside the battery. (This does not apply to gel type batteries.)
Change the oil.
An oil change increases the lubrication protection for your engine. Switching to heavier viscosity motor oil during the hot weather is a good idea, especially for older high mileage engines.
Replace windshield wipers.
Natural rubber wiper blades last one year or less. Sun exposure, extreme head and cold accelerate their aging. If wipers streak or smear, it’s time to replace them.
Check your tires.
Check the inflation pressure in all the tires. Under-inflation makes the tires run hot and increases the risk of a blowout.
Wax your car.
Waxing your car with some type of protectant helps shield its paint from the ultraviolet rays of the sun.
A sun shade for the windshield reflects light so the interior of your vehicle doesn’t get as hot when parked in direct sunlight. Closing the sunroof sunshade and leaving windows cracked open lightens the cooling load on the air conditioner when first starting the vehicle and helps prevent getting a hot seat or burning yourself on hot interior surfaces.
Carrying a bottle of water in the car helps when you are driving for a long time. If you’re in a convertible, a hat helps keep the sun off your head.
