Preparing Your Car for UAE Summer

UAE summers push cars to their limits. The National Centre of Meteorology recorded 51.8°C at Sweihan, Al Ain, on 1 August 2025. Gulf News described it as the highest August temperature in nine years. A bit of preparation in late spring can save you from a breakdown in July.

What goes wrong in the heat

In May 2026, during the Eid Al Adha break, Khaleej Times spoke to recovery operators and mechanics about why motorists were getting stranded. Their answers were consistent:

• Overheating was the most common issue. A recovery operator in Kalba said he attended seven breakdowns in two days, mostly from overheating, and that many drivers set off without checking coolant levels.

• Batteries often seem healthy on short commutes but fail on longer drives, a Sharjah Industrial Area mechanic said. He added that slow engine starts are an early warning sign that drivers often ignore.

• Tyres were overlooked. Worn tyres and incorrect pressure cause problems on long highway journeys.

• AC failures left cars drivable but families uncomfortable in extreme heat.

1. Cooling system

• Check the coolant level in the reservoir (with the engine cold) and top up only with the correct coolant.

• Look for leaks, wet hoses or white or green residue.

• Make sure the radiator and condenser at the front aren't packed with dust, sand or debris.

• If the temperature gauge rises above normal, stop when it's safe and turn off the engine. Never open a hot radiator cap.

2. Battery

Gulf News has reported industry experts explaining that summer heat speeds up battery electrolyte evaporation, while constant AC use puts extra strain on the battery. Get the battery and charging system tested before the peak months, especially if the battery is a few years old. See car battery replacement in Dubai.

3. Tyres

According to Ministry of Interior records reported by Khaleej Times, 22 accidents in the UAE in 2023 were caused by tyre bursts. Gulf News reported that the Ministry of Interior has warned that summer heat significantly increases tyre-related risks.

• Check pressure in the morning, when the tyres are cold, using the figures on the door-frame sticker.

• Check the manufacturing date: the last four digits of the DOT code give the week and year.

• Look for cracks, bulges and uneven wear.

• Remember that driving on unfit tyres carries a Dh500 fine, four black points and a one-week impoundment under Article 82 of the Federal Traffic Law.

4. AC

Weak cooling before summer usually gets worse, not better. Common causes include refrigerant leaks, a blocked condenser, fan faults and a tired compressor. See our guide on car AC problems and compare car AC repair across the UAE.

5. Protect the cabin and paint

• Use a windscreen sunshade and park in shade where you can.

• Window film reduces heat build-up, but the UAE limit on side and rear windows is 50%, according to Gulf News. See window tinting in Dubai.

• Don't leave pressurised cans, power banks or lighters in a hot car.

6. Going away for the summer?

Dubai Municipality can fine owners Dh500 for leaving a vehicle dirty and unattended in a public place. Khaleej Times reported that the Municipality urged residents not to leave cars unattended for long periods, particularly during summer holidays. Arrange for someone to start and wash the car, or park it in a covered, private space.

Pre-summer checklist

• Coolant level and no leaks

• Battery and charging system tested

• Tyre pressure, age and condition, including the spare

• AC cooling properly

• Wiper blades and washer fluid (dust storms happen)

• Service up to date
