As temperatures start to rise, your vehicle has to work harder to stay cool — and if something isn’t working properly, overheating can quickly become a serious (and expensive) problem.
At Birway, we often see overheating issues increase during warmer weather, especially before summer holidays, long journeys and busy working periods for vans and commercial vehicles. The good news is that many overheating problems can be avoided with a few simple checks and regular maintenance.
In this guide, we’ll explain the common causes of overheating, the warning signs to look out for, and how to help keep your vehicle running safely through the warmer months.
Why vehicles overheat in warmer weather
Your engine generates a huge amount of heat while driving, and your cooling system is responsible for keeping temperatures under control. During summer, higher outside temperatures make it harder for the cooling system to do its job — especially in slow-moving traffic, on long motorway journeys, while towing or when carrying heavy loads. If there’s already a weakness somewhere in the system, warmer weather is often when problems begin to appear.
Check your coolant levels regularly
Coolant is one of the most important parts of your vehicle’s cooling system. It absorbs heat from the engine and helps prevent temperatures from rising too high. If coolant levels drop too low, your engine may struggle to stay cool — increasing the risk of overheating and potential engine damage. Low coolant levels can also indicate a leak somewhere in the system, so it’s not something to ignore. At Birway, we can check coolant levels, pressure test the cooling system and identify leaks before they turn into bigger repairs.
Know the warning signs of overheating
Your vehicle will usually give you warning signs before serious overheating happens. Common warning signs include:
- the temperature gauge running hotter than normal
- steam coming from under the bonnet
- warning lights appearing on the dashboard
- reduced performance or unusual smells
If your engine temperature suddenly rises, it’s important to stop driving as soon as it’s safe to do so. Continuing to drive an overheating vehicle can cause serious damage to the engine.
Make sure your cooling system is working properly
Your radiator, cooling fan, thermostat and water pump all work together to control engine temperature. Over time, parts of the cooling system can become worn, blocked or damaged. Radiators can collect dirt and debris, hoses can weaken, and thermostats can fail without much warning. Even a small issue can affect how efficiently the system cools your engine during hotter weather. We can inspect your full cooling system to make sure everything is operating correctly before summer journeys begin.
Regular servicing helps prevent overheating
Many overheating problems begin as small faults that could have been spotted early during routine servicing. Worn hoses, ageing coolant, faulty fans or failing water pumps can all lead to overheating if left unchecked. Keeping your vehicle properly serviced reduces the risk of unexpected breakdowns and helps keep everything running reliably through the warmer months. At Birway, we can carry out servicing and cooling system checks for cars, vans and commercial vehicles.
Prepare before long journeys
If you’re planning a holiday, road trip or long-distance journey this summer, it’s always worth having your vehicle checked beforehand. Hot weather, traffic and long motorway drives can put extra strain on your engine and cooling system — especially in older vehicles or heavily loaded vans and camper vans. A quick inspection before travelling can help avoid breakdowns and give you peace of mind while you’re on the road.
