Yuma's heat season.

Extreme heat can lead to some drivers finding themselves stranded at the roadside, with the weather at over one hundred degrees that is overwhelming and dangerous. The following tips can help you avoid becoming one of those drivers.

Check your Coolant.

Cooling systems protect engines from overheating and should be checked frequently. Between flushes, make sure the coolant is filled to the proper level by checking the overflow reservoir. CAUTION! – Never remove the radiator cap when the engine is hot – boiling coolant under pressure could cause serious burns. Periodically inspect hoses and drive belts.

Is your battery prepared for high temperatures?

Summer heat can harm your battery more than winter temperatures. Heat and vibration are a battery’s worst enemies, leading to internal breakdown and eventual failure. While you can’t do much about the heat, you can make sure your battery is securely mounted to minimize vibration. Another potential problem is faster evaporation of battery fluid, which leads to corrosion on terminals and connections. Clean any corrosive buildup from battery terminals and cable clamps, and ensure the clamps are tight enough that they will not move. If a battery is more than three years old, it’s a good idea to have it tested by a trained technician to determine how much longer it will last.


Make sure fluids are at appropriate levels. Most engine fluids lubricate and serve as coolants by helping carry heat away from critical components. When fluid levels are low, the cooling effect is reduced, which increases the possibility of overheating. Periodically check all vehicle fluids, including motor oil, transmission fluid, power steering fluid and brake fluid, to ensure they are at appropriate levels. 

Check tire pressures.

Driving on under-inflated tires can cause tires to overheat and increase the likelihood of a blowout, especially when road temperatures are extremely high. In the latest statistics reported from the National Highway Traffic Safety Administration, tire blowouts are estimated to cause more than 400 deaths and more than 78,000 crashes each year. That is why it's important to check your car’s tire pressures (including the spare) at least once a month. For the most accurate reading, check tire pressures when the tires are cold. Always follow inflation pressure recommendations in your vehicle owner’s manual.
