Keep Your Classic Car from Overheating this Summer

Summer is almost upon us and although that means much more time spent driving around the countryside, enjoying hearty pub lunches and more weekends away, it can also bring a few challenges, especially for the classic car owner, one of the biggest being the problem of overheating.

If you have a classic car that was manufactured before electric fans and extensive weather-testing were the norm, then it could be far more prone to overheating than your neighbour’s brand new Ford Focus, although your vehicle is probably much more stylish. So, what can you do to lower the risk and ensure you don’t end up with a huge garage bill this summer?

Perform Regular Checks

If you want to prevent your classic car from overheating, should the sun actually grace us with her presence this summer, the most important thing that you can do is stay vigilant, Every time you’re out in the car in the heat of the sun, when you get home you should check that the belts, fans, radiators, hoses and anything else that you can think of that could have an effect on the temperature, are in good condition. You should also keep a close eye on the temperature gauge while you’re driving because it will give you some warning that things are about to take an unwanted turn.


Book a Service

If you want to be extra sure that your car is in good condition and able to perform well even in the heat, consider booking a vehicle specific service. Sol, if you have a Mercedes, find a garage specialising in Mercedes servicing or if you have a BMW, have a BMW dealer check it out. They should be able to really pinpoint any potential issues and fix them before you start driving around in the sunshine.

Clean the Radiators

Perhaps, the part of your vehicle that is most likely to overheat are the radiators. Luckily, you can minimise the chances of this happening by using a pressure-nozzled garden hose to get rid of dust, grime and other blockages that could cause them to overheat. Clean until the water enters and exits the radiators almost instantaneously and you should be good to go.


Invest in Better Radiator Caps

Once you’ve done that, consider buying a heavier radiator cap which will be far more resilient and less likely to cause you any problems.

Ensure the Thermostat is Working

Your car’s thermostat is what will ensure that your coolant is circulating through your vehicle’s system as it should. So, check that it still opens up in the heat as it should, and if it doesn’t I’m, afraid you’re going to have to replace it.

Monitor Fluids

You should always monitor the levels of coolant and water in your vehicle because if they run too low you could end up blowing a gasket and having coolant leak out of the cooling system, which could lead to your vehicle overheating very quickly indeed.


Planning to use your car this summer? Make sure it’s ready for it.

Wrap Exhaust Components

If you place exhaust wrap on all of your exhaust components, apart of course, from the catalytic converters and mufflers, less heat will make it’s way to the underside of your vehicle and gas will be able to escape faster, for a cooler car.

I hope your summer is cool this year!
