What You Need to Know When Driving in a Heatwave

Scorching temperatures associated with heatwaves are putting drivers in the UK not only at an increased risk of car breakdown but driving in a heatwave can pose new dangers to your safety. While most drivers suffice to crank up their air conditioning while driving in a heatwave, such extreme weather conditions can be hazardous for the drivers as well as their vehicles. ExpressPASS Driving School can help you prepare for driving in extreme weathers such as a heatwave.


Coolant System

Both your car and your safety while driving are at an increased risk in a heatwave. As temperatures soar and the sweltering heat takes its toll, a car’s engine and its coolant system can suffer. You must ensure that the level of the coolant is between the min/max marker while driving in a heatwave. You can even ask a garage assistant to inspect and top up the coolant system of your car for possible leaks. Refer to you driving instructor at ExpressPASS Driving School on tips to check your car coolant system.


Air Con System

If you are planning for some serious summer driving, then you will certainly want to use your vehicle’s air conditioning. Before you head out in a heatwave, get your air con checked before you take any extended excursions, especially if you have not used it for a while. The air con system might have lost refrigerant gas since you last used it, or it might not be functioning as well as it should because of dirt and bacteria deposits. Take your car to a specialist to be serviced and re-gassed, as this is certainly not a DIY job! Check with your driving instructor at your driving school on advice to keep your air con in good condition during summer.


Battery Life

Heatwaves can be particularly harmful to your car batteries. Hot temperatures can shorten the life of batteries and lead to potential breakdowns, so always ensure they are in good condition before pulling out of your driveway in a heatwave.


Batteries contain a liquid being a mixture of acid and water. It also generates heat and along with gaseous venting causes the liquid to slowly evaporate. If the fluid level in battery gets too low, the internal plates in battery are not protected and damage can occur. Damaged cells means, battery produces less voltage. However, with standard acid flood batteries it is possible to top up the liquid, extending the battery’s life.An Intensive Driving Course session at ExpressPASS Driving will help you learn to drive in all weather conditions safely.
