Summer Car Checklist for West Bromwich Drivers

By Sun Garage, Owner, Sun Garage · 3 June 2026 · 5 min read

Summer is a different kind of test for your car

It's easy to assume summer is the easy season for cars – no ice, no grit, no freezing mornings. But heat, longer journeys and fuller cars all put extra strain on components that have often been quietly wearing down all winter without you noticing.

At Sun Garage we see a real pattern in what fails in the warmer months: overheating, tyre problems and flat batteries all spike as soon as the temperature and mileage go up. A short checklist before a long trip or the school holidays can save you a breakdown on the hard shoulder.

Cooling system: the number one summer failure

Your engine works hardest to stay cool in hot weather, especially in stop-start traffic or on a motorway run with the air con on. A cooling system that was borderline all winter often tips over into overheating once temperatures rise.

Coolant level, condition and hose integrity are quick things to check but are the difference between a normal drive and a roadside breakdown with steam pouring from the bonnet.

Never remove a coolant cap on a hot engine – the system is pressurised and can cause serious burns. Let it cool fully first.

Tyres take more punishment in the heat

Hot tarmac and fully loaded cars (think roof boxes, luggage, extra passengers) put more stress on tyres than most drivers realise. Under-inflated tyres flex more, generate more heat, and are at greater risk of a blowout on a long motorway journey.

A five-minute tyre check before a long trip

Before any longer journey, it's worth checking each tyre properly rather than just glancing at them:

  • Tread depth – legal minimum is 1.6mm, but 3mm gives noticeably better grip in wet weather
  • Tyre pressure – check when cold and adjust for extra load if the car is full
  • Sidewalls – look for cracking, bulges or damage, especially if the car has been kerbed
  • The spare wheel or repair kit – often forgotten until it's needed

Battery, fluids and the parts people forget

A car battery actually has a harder time in extreme heat than in the cold – high temperatures accelerate the chemical reactions inside that wear it out. A battery that's already a few years old can fail without warning on a hot day.

It's worth running through the less obvious checks too before a longer summer trip.

Quick pre-trip checks worth five minutes:

  • Oil level and condition – low oil makes the engine work harder and run hotter
  • Screen wash – top up and use a proper solution to clear bug splatter and glare
  • Wiper blades – perished rubber smears in sudden summer showers
  • Air con performance – see our separate guide if it isn't blowing cold
  • Battery terminals – clean and free of corrosion

None of these take long individually, but together they cover most of what actually strands drivers on a hot day.

Why a pre-summer service makes sense

A full service catches most of the above in one visit rather than piecing it together yourself in a car park. We check oil, coolant, brakes, tyres and battery condition as standard, and flag anything that's borderline before it becomes a breakdown.

For anyone doing a long family trip, towing a caravan, or just clocking up more miles than usual over the summer, a service beforehand is genuinely one of the cheapest forms of insurance against being stuck at the roadside.

Book in before the school holidays rush

Every year, the same weeks either side of the school holidays are our busiest for pre-trip checks and services. If you've got a longer journey planned, it's worth booking earlier rather than leaving it to the week before.

Call Sun Garage on 0121 553 0296 or book your summer service online. We'll get your car road-trip ready and give you honest advice on anything that needs attention – no scare stories, just a clear rundown of what matters.

Driving further afield this summer? Ask us to check your spare wheel or emergency kit too – often overlooked until it's needed on the roadside.
