A Dubai summer is hard on cars. Temperatures regularly climb past 45°C, tarmac gets hotter still, and a car that ran perfectly in February can start struggling by June. Most summer breakdowns here are preventable, and they usually come down to the same few things: a tired battery, low coolant, worn tyres, and an air conditioner that has not been serviced. Do these checks before the hottest months arrive, and you are far less likely to end up waiting for recovery on the side of Sheikh Zayed Road in the midday heat.
Check the battery first
Heat is the biggest battery killer in the UAE. High temperatures speed up the reactions inside a battery and evaporate its fluid, so a battery that might last four or five years in a cooler country often lasts only two to three years in Dubai. If yours is more than two years old, get it tested before summer, even if the car still starts fine. Warning signs include a slow, laboured start in the morning, dimming headlights at idle, and a battery warning light.
Top up and test the coolant
Your cooling system works overtime in summer, and low or old coolant is a common cause of overheating. With the engine completely cold, check that the coolant in the reservoir sits between the minimum and maximum marks. Never open the radiator or coolant cap on a hot engine, as the system is pressurised and can spray scalding liquid. Use the coolant type your manufacturer recommends rather than plain water, and if the fluid looks rusty or has not been changed in a couple of years, have the system flushed and refilled, and ask the workshop to check the hoses, belts, and radiator fan.
Give your tyres extra attention
Hot roads and under-inflated tyres are a dangerous combination, because heat builds up in the tyre wall and raises the risk of a blowout, especially on long motorway drives. Check tyre pressure every two weeks in summer, ideally when the tyres are cold, and match the figure on the sticker inside the driver’s door rather than the number on the tyre itself. Look for cracks, bulges, and worn tread, and check the age of the tyre too: rubber hardens in this climate, so tyres older than about five years deserve a professional opinion even if the tread looks fine. Do not forget the spare.
Service the air conditioning early
In Dubai, air conditioning is not a comfort extra; it is essential equipment, and it is much easier to service in spring than to repair in July when workshops are busiest. If the air is not blowing properly cold, the system may need the gas topped up, the cabin filter replaced, or the condenser cleaned of dust and sand. A musty smell usually points to the filter or mould in the system, and if cooling has gradually weakened, get it checked before it fails completely.
Protect the cabin from the sun
A parked car in Dubai can heat up like an oven within minutes. A reflective windscreen sunshade makes a real difference to cabin temperature and protects your dashboard, steering wheel, and seats from cracking and fading. Where you can, park in shade or covered parking, and avoid leaving electronics, aerosols, lighters, and bottled drinks in a hot car, as heat damages all of them.
Never leave children or pets in a parked car
This is the most important point in this guide. Temperatures inside a parked car can rise to life-threatening levels in a very short time, even on a day that does not feel extreme and even with a window slightly open. Never leave a child or a pet alone in the car, not even for a quick stop at a shop. It is dangerous, and it can also bring serious legal consequences in the UAE.
What to keep in the car
- Drinking water, for you and for emergencies
- A phone charger or power bank, so you can always call for help
- A warning triangle and a basic torch
- Jump leads, or the number of a battery and recovery service saved in your phone
- Sunglasses and sunscreen, in case a breakdown means waiting outside the car
- A sunshade, stored where you will use it
None of this takes long. One pre-summer check covering the battery, coolant, tyres, and AC handles most of what Dubai’s heat throws at a car — and it is far better done in a workshop than discovered on the motorway.
