Each season brings new challenges for vehicle upkeep, and summer is no exception. Rising temperatures can affect your cooling system, tyres, battery and interior comfort.
To ensure your family car is ready for warm-weather journeys, follow these practical maintenance tips.
Inspect and Maintain Fluid Levels
Proper fluid levels are essential to keep your engine running smoothly and prevent overheating, so check your owner’s manual for correct levels. Key fluids to check include:
- Coolant/antifreeze: Top up if levels are low and ensure the system is flushed as per your car’s service schedule.
- Engine oil: Check the dipstick and refill as needed. Change the oil if it hasn’t been done recently.
- Windscreen washer fluid: Refill regularly to keep your windscreen clear from bugs and dust.
- Brake fluid: Check that it sits between the minimum and maximum markers.
Tip: Review these fluids weekly during the hotter months. Most have visual level indicators under the bonnet.
Inspect and Replace Tyres as Necessary
Hot weather can increase tyre pressure, heightening the risk of blowouts. Before any journey:
- Check tyre pressure when tyres are cold and match the levels recommended in your vehicle’s manual or on the driver-side door panel.
- Inspect tread depth. Replace tyres once they reach 3mm, even though the legal minimum is 1.6mm.
- Assess tyre age. Replace them if they are six years old or more, regardless of appearance.
If you need new tyres fitting, choose an auto centre offering warranties instead of replacing them yourself for peace of mind.
Test the Air Conditioning System
An efficient air conditioning system is vital for summer comfort, particularly for children and pets. If your AC isn’t cooling properly:
- Check for unusual smells or weak airflow.
- Book a re-gassing service if needed.
- Address musty odours, which could indicate mould in the vents.
Servicing the AC early in the season can prevent uncomfortable journeys and help maintain good air quality inside the cabin. If you spot unpleasant smells, take your car for a clean-out before they get worse.
Verify Battery Health and Electrical Components
High temperatures can shorten battery life. Heat speeds up chemical reactions, causing internal fluid to evaporate and components to corrode.
- Visually inspect your battery for corrosion or swelling.
- Get it tested if it’s more than three years old.
- Check connections for tightness and cleanliness.
Visit a garage for a battery health check in spring to avoid breakdowns during summer travel.
Additional Checks Before a Road Trip
- Air filters: Replace if clogged with dust or pollen.
- Lights: Test all bulbs, including indicators and brake lights.
- Wiper blades: Replace if streaking or squeaking.
- Emergency kit: Stock up on water, a first aid kit, and basic tools.
