As temperatures soar across South Africa, the extreme heat poses serious risks to both drivers and their vehicles. Taking the right precautions before, during, and after your journey can mean the difference between a safe trip and a dangerous situation or breakdown.
Before you hit the road
Start by giving your vehicle a thorough check. The CEO of MasterDrive, Eugene Herbert, says: “Inspect coolant levels and top up, if necessary, as your engine will be working overtime in this heat. Additionally, be aware that most modern systems are sealed, thus if in doubt, visit your dealership or consult an expert such as an approved RMI workshop,” says Herbert.
Other steps to take:
- Check your oil levels, since extreme temperatures can cause oil to thin and lose viscosity.
- Batteries are vulnerable during heatwaves, as heat speeds up degradation. Ensure terminals are clean and connections tight.
- Conduct a tyre check, especially if you hit a pothole recently. Heat causes air to expand which can cause blowouts if they are overinflated or worn.
Drivers should adequately prepare for a hot day in the car as well. “Be sure to apply sunscreen. While windshields are more effective at blocking most UV rays, side and rear windows often do not. They allow harmful UVA rays to penetrate the vehicle which increases skin cancer risk, particularly on the right side of the body of people that spend significant time driving.
“Pack plenty of water, and wear light, breathable clothing. Try travel during cooler parts of the day like earlier in the morning or later in the afternoon whenever possible. Check your route for rest stops and air-conditioned facilities,” says Herbert.
During your journey
Keep your air conditioning running at optimum by using it on recirculation mode rather than pulling in hot outside air. “In older vehicles, give your AC occasional breaks for a few minutes every hour to prevent overheating. AC systems also require regular maintenance to optimise and prolong functioning.”
Other steps to take:
- Stay hydrated. Dehydration impairs concentration and reaction times.
- Take the recommended break every two hours for safety and use it to cool down too.
- Watch dashboard warning signs with extra vigilance. If your engine overheats, pull over safely, and call a mechanic to avoid further damage to the vehicle.
After your trip
Once you’ve reached your destination, park in shade if available. “If you noticed any concerning symptoms from your vehicle during the journey, schedule a mechanic’s inspection promptly. Heat can accelerate wear and tear, potentially causing problems that worsen over time.
“Again, do not neglect yourself either. Rehydrate thoroughly but also be aware of signs of heat exhaustion, including dizziness, nausea, or excessive fatigue,” says Herbert.
By taking these precautions, you will protect both yourself and your vehicle from the harsh effects of the current heat being experienced in South Africa, ensuring safer travels for everyone on the road.
