Summer can take its toll on your car without you noticing. High temperatures, long trips, motorway miles, air conditioning running for hours and the car loaded with more weight than usual can accelerate the wear of some components.
And the problem is that many breakdowns do not appear during the holidays, but a few weeks later.
That is why September is a good time for a basic check-up. There is no need to wait for a warning light to appear on the dashboard or to hear a strange noise.
Below we tell you what to check on your car after summer and what signs may indicate that a part needs attention.
Why is it worth checking your car after summer?
During the holidays we tend to demand more from the vehicle than during the rest of the year.
A long trip means many hours of continuous operation and high temperatures can particularly affect certain components.
Also, if you have driven hundreds or thousands of miles during the holidays, some components may have reached their wear limit sooner than expected.
A timely check can help you detect small problems before they end up becoming a more expensive breakdown.
1. Check the condition of your tyres
Tyres are one of the first things you should check.
After long trips, check both the pressure and the tread wear.
It is also worth looking out for:
Cuts or cracks.
Uneven wear.
Bulges or deformations.
Sidewall damage.
Frequent pressure loss.
Uneven wear can also be a clue to other problems related to alignment, suspension or steering.
How do I know the age of a tyre?
You can check the DOT code on the sidewall.
Its last four digits indicate the week and year of manufacture. For example, 4025 means the tyre was manufactured during week 40 of 2025.
This allows you to know its age even when it apparently looks in good condition.
2. Pay attention to the brakes
More miles also mean more braking.
If during the summer you have made long journeys, especially on mountain roads or with the vehicle loaded, it is worth paying attention to the braking system.
Some signs that may indicate that something is not working correctly are:
Squeaking when braking.
Vibrations in the pedal or steering wheel.
Increased stopping distance.
Pedal feeling too soft.
Metallic noises.
Brake warning light on.
Do not ignore these symptoms. Brakes are a fundamental safety element.
3. Check the battery
When we think of battery problems we usually associate them with winter, but high temperatures can also affect its performance and accelerate its deterioration.
If after the summer you notice that the car struggles to start, the lights lose intensity or seemingly inexplicable electrical problems appear, it is worth checking its condition.
It is also important to take into account the age of the battery and to check that the terminals show no corrosion.
A deteriorated battery can leave you stranded precisely when you least expect it.
4. Check the cooling system
This is one of the systems that works the hardest during the hot months.
Its function is to keep the engine within a suitable operating temperature.
That is why, after a particularly hot summer or after driving many miles, check the coolant level always following the manufacturer's instructions and with the engine in safe conditions to do so.
Also pay attention to possible:
Coolant leaks.
Stains under the vehicle.
Abnormal temperature increases.
Dashboard warnings.
Irregular fan operation.
An apparently small problem in the cooling system can end up causing a major engine breakdown if not detected in time.
5. Check all the car lights
When was the last time you checked all your lights?
It is one of the simplest checks and yet we often do not realise that a bulb, a headlight or a light is showing a problem until someone tells us.
Check:
Low beam lights.
High beam lights.
Turn signals.
Brake lights.
Position lights.
Fog lights.
Reverse light.
Also check the physical condition of headlights and rear lights.
A deteriorated, damp, broken or very opaque lens can reduce visibility and require repair or replacement.
6. Don't forget the windshield wipers
After months of heat and sun exposure, the wiper blades may have deteriorated.
And you probably won't realise until the first rainy day.
If when using them they leave marks, make noise, skip over the windshield or do not clear the water properly, it may be time to replace them.
It is also worth checking the windshield washer fluid level.
Getting this component ready now can save you from discovering the problem when bad weather arrives.
7. Check the filters
Filters are another often overlooked maintenance item.
After many miles, they may have accumulated dirt, dust and particles.
Depending on the vehicle and its maintenance, it is particularly worth monitoring:
Air filter: helps prevent certain particles from entering the engine.
Fuel filter: helps protect the fuel system against impurities.
It does not mean you should replace them automatically after every summer. The right approach is to follow the maintenance intervals established for your vehicle and check their condition when appropriate.
What happens if you find that you need to change a part?
Finding a deteriorated component does not necessarily mean you have to buy a new part.
Depending on the type of repair, a used original spare part from a compatible vehicle can be an alternative worth considering.
Engines, gearboxes, headlights, rear lights, mirrors, alternators, starter motors, body parts, control units, seats or rims are some of the spare parts that can be found at an authorised salvage yard.
The key is to correctly identify the part.
Before buying a spare part, check the reference
This point is particularly important.
Two cars of the same model and year do not necessarily use exactly the same part.
A different engine, a different version or even certain changes made by the manufacturer can alter the component's reference.
Therefore, before buying a spare part, try to locate the OEM reference or manufacturer's reference of the original part and check its compatibility.
At Recoautos you can search for spare parts for your vehicle and, if you have any doubts about which part you need, ask before making your purchase.
Is it worth checking the car even if it apparently runs fine?
Yes.
The very purpose of a preventive check is to find possible signs of wear before a breakdown occurs.
After the summer, pay special attention to any change in your car's usual behaviour:
Noises that were not there before.
Vibrations.
Difficulty starting.
Warning lights on.
Temperature increase.
Loss of power.
Abnormal consumption.
Stains or fluids under the vehicle.
Your car usually gives warning signs before certain problems get worse. The key is knowing how to recognise those signs.
A check-up now can prevent problems later
September doesn't just mean going back to work and getting back into routine. It can also be a good time to check how your car has come through the summer.
Tyres, brakes, battery, cooling system, lighting, windshield wipers and filters are good starting points.
And if during the check-up you find that a part needs replacing, correctly checking its reference and compatibility can save you from mistakes when buying the spare part.
At Recoautos you can find used original spare parts for different makes and models, with real stock available online.

Frequently asked questions about checking your car after summer
What should I check on my car after a long trip?
It is worth paying attention to tyres, brakes, fluid levels, battery, cooling system, lighting and any noise or abnormal behaviour that appeared during the trip.
Can heat damage a car battery?
High temperatures can contribute to battery deterioration and accelerate certain internal processes. If you notice starting difficulties after the summer, it is worth checking its condition.
How do I know if my tyres are too worn?
In addition to checking that they meet the legal tread depth requirements, look for possible cracks, deformations and uneven wear. If you have any doubts about their condition, consult a professional.
What symptoms indicate brake problems?
Noises when braking, vibrations, changes in pedal feel, increased stopping distance or warning lights may indicate that the system needs a check-up.
Can I use salvage parts to repair my car?
There are numerous components that can be legally reused from authorised centres. It is essential to acquire parts suitable for the vehicle and to check their reference and compatibility.
How do I know which part is compatible with my car?
One of the most reliable ways to identify a spare part is to check the OEM reference of the part and cross-reference it with the exact vehicle data. It is not advisable to rely solely on make, model and year.
