Summer Car Care Checklist

How to Prepare Your Car for Warmer Weather

After a (relatively) sunny spring, the weather is hopefully going to get warmer, and thoughts are turning to summer – the holiday season. That means drivers up and down the country will be hitting the road, whether that’s to commute or to get away from it all for a day, a week or even longer. The hot weather can cause problems for cars, with elevated temperatures both in the cabin and in the engine bay. But with a little TLC, cars can still run smoothly through the summer months, and whether you're planning long road trips, commuting in the sun, or the occasional weekend getaway, preparing your car for summer is essential. 

Such preparations don’t have to be daunting tasks. Simple measures can ensure that your car runs smoothly, efficiently and safely, allowing you to enjoy all the adventures that the summer  has to offer. So, here’s our step-by-step guide on how to get your vehicle ready for the holiday season.

1. Check Your Air Conditioning System

When the weather gets warmer, your car’s air conditioning system becomes your best friend, so it’s important to make sure your air con is in good working order before the temperatures rise. Air conditioning units can sometimes fail after a long winter of inactivity, or they may lose refrigerant, both of which prevent that cooling air from reaching the cabin.

Now, then, is the time to test the air conditioning system by turning it on full blast and checking if it cools effectively. If you notice weak airflow, strange smells, or warm air, consider getting it serviced or recharged by a professional.

2. Inspect the Tyres

Temperature affects air pressure, and tyres that were perfectly inflated on a 10-degree winter’s morning may not be at the right pressure on a sunny afternoon in July. Incorrectly inflated tyres can cause a blowout or increased wear, and summer roads, especially on long trips, tend to get hotter, which can place extra stress on the rubber. So, it’s critical that you check tyres are at the right pressure and in good condition before heading out on a long summer road trip.

You can check the tyre pressure using a reliable gauge. Both over- and under-inflation can cause issues, so make sure the pressure matches the placards in the vehicle (usually found inside the car door frames, or sometimes inside fuel filler flaps). While you’re at it, inspect your tyres for any visible damage such as cracks, punctures, or bulges. If the tread is worn down, it’s time to replace the tyres.

Tyre problems are a common hindrance for drivers, particularly after a harsh winter, so it’s also a good idea to check your car’s spare tyre, jack and tools (if it has them), especially if you’re going on a road trip.

3. Top Up Fluids

Cars rely on a variety of fluids to function efficiently, and a hot summer’s day can put a strain on these systems. Regularly topping up or changing fluids is a simple yet effective way to keep your vehicle in peak condition.

Drivers should regularly check the oil level all year round and should change it in line with the car’s service schedule. Oil keeps the engine running smoothly, so if your level is low, pour in a little more to prevent any problems. Make sure you’re using the right oil, though, and if you’re in any doubt, it’s best to have the work carried out by a professional. 

At the same time, drivers should ensure that their coolant levels are sufficient. A low coolant level can lead to overheating, which can cause significant engine damage. Similarly, brake fluid and power steering fluid levels should be checked before a long drive, and topped up if they are low.

4. Replace Your Windscreen Wipers

It might sound strange in summer, but hot weather and high humidity can cause thunderstorms to spring up surprisingly quickly, so fully functional windscreen wipers are a must-have. Look at the full length of the wiper blade and check for any splits, while also checking the rubber is still flexible and the wipers clear water from the window effectively. If your wipers are streaking, skipping, or making a squeaky sound, it’s probably time to replace them.

If you need to replace your wiper blades, make sure you do so with wipers of the appropriate size for your car. And at the same time, it’s a good idea to check the washer fluid reservoir is full. The summer months see lots of flies in the air, and they can be difficult to remove without some washer fluid to help. Consider bringing insect remover on road trips, too, in order to keep your windscreen, lights and number plates clear.

5. Check the Battery

Batteries are notoriously sensitive to temperature changes, and summer heat can take a toll on your car’s battery, especially if it's old. Extreme temperatures, whether hot or cold, can lead to reduced battery life, so it’s essential to check that your battery is in good working order before setting out on a road trip.

Inspect the battery for any signs of corrosion around the terminals. If there’s visible build-up, clean it carefully with a wire brush. If you notice your battery is struggling to start your car, consider having it tested at a garage. It may just need charging, either by doing a long drive or using a dedicated battery charger, but it may be a sign of impending problems.

6. Check the Belts and Hoses

Many cars’ cooling systems are controlled by a selection of rubber belts and hoses, which are critical components in keeping your car’s engine cool. However, hot weather can make them more prone to cracking, warping, or even snapping, causing serious issues and hindering your journeys.

Drivers should look for any visible cracks, wear, or signs of leaks on the belts and hoses around their car’s engine bay. Ensure that the radiator hoses are not brittle, as these are crucial in keeping the engine from overheating. If you notice any issues, replace the belts or hoses – or have a garage inspect them – before they fail on you during a long drive.

7. Inspect the Brakes

Perhaps the most important components on any car, it’s crucial that your brakes are in good condition at all times. The car’s brakes should regularly be inspected as part of routine maintenance, but if you notice any obvious problems with your brakes during a visual inspection, or while driving, have them checked out by a qualified mechanic. Noises, unusual feelings through the brake pedal or strange braking behaviour could all be signs of a problem, so get those issues checked as quickly as possible.

8. Prepare for Long Road Trips

‘Fail to prepare, prepare to fail’ is an old saying, but one that’s true of any car journey. As well as all the checks detailed above, it’s important to make sure you’re as ready to go as your car is. Not only should you have a clear idea of your route (technology isn’t always reliable, so carrying a paper map is a good idea), but carry some food, water and a first-aid kit in case you get stranded, along with a mobile phone charger to ensure you can call for assistance. It’s important to plan in some stops and breaks on your route, too, to help keep yourself alert at all times.
