If you own a car in the UAE, you already know what’s coming. Temperatures are about to push past 50°C in parts of the country, and that kind of heat doesn’t just make your commute uncomfortable — it puts real stress on your vehicle’s mechanical and electrical systems. The good news? A little preparation goes a long way.
We’ve put together this pre-summer maintenance checklist based on what we see across thousands of inspection-verified cars every year. These are the issues that come up again and again — especially on popular models like the Toyota Camry, Nissan Kicks, and Honda Civic that dominate UAE roads. Here’s what to check before the heat hits full force.

1. Get Your Car Battery Tested (Don’t Wait for It to Die)
Extreme heat is harder on car batteries than cold weather. In the UAE, a battery that’s over two years old is already living on borrowed time during summer. Heat accelerates chemical degradation inside the battery, and a weak one can fail without warning.
Model-specific note: The 2019–2022 Nissan Kicks uses a smaller-capacity battery (typically 45Ah). If yours hasn’t been replaced since purchase, get it load-tested now. Toyota Camry owners with the 2.5L engine generally have more robust batteries, but anything past 30 months deserves a check.
Most garages and quick-service centres across Dubai and Abu Dhabi offer free battery testing. It takes about five minutes.
2. Service Your AC System Before You Actually Need It
Your air conditioning works hardest between May and October. A system that’s low on refrigerant or has a clogged cabin filter won’t cool properly — and it’ll strain the compressor, which is an expensive fix.
Here’s what to ask for:
- Refrigerant level check and top-up (R-134a for most pre-2020 models, R-1234yf for newer ones)
- Cabin air filter replacement — these should be swapped every 15,000 km in dusty UAE conditions
- Compressor and condenser inspection for leaks or damage
Model-specific note: Honda Civic (10th and 11th gen) owners sometimes report weak AC performance at idle in heavy traffic. This is often traced to a dirty condenser — road dust and sand build up on the front-mounted unit. A simple pressure wash can restore cooling performance noticeably.
3. Check Your Coolant Level and Condition
Coolant (also called antifreeze) doesn’t just prevent freezing — it raises the boiling point of the liquid circulating through your engine. In 50°C ambient temperatures, your engine bay can reach well over 100°C. Old or diluted coolant won’t protect against overheating.
Open the coolant reservoir (when the engine is cold) and check two things:
- Level: It should sit between the MIN and MAX lines.
- Colour: Fresh coolant is bright (green, pink, or blue depending on the type). If it looks brown or murky, it needs a full flush and replacement.
Important: Don’t mix coolant types. Toyota models typically use pink long-life coolant, while many Honda and Nissan models use blue or green. Check your owner’s manual or ask your service centre.
4. Inspect Your Tyres — Pressure and Condition
Hot asphalt in the UAE can reach 70–80°C on a summer afternoon. That superheated road surface increases tyre pressure as you drive, and tyres that are already over-inflated or worn thin are at risk of a blowout.
Here’s what to do:
- Check pressure when tyres are cold (before driving or early morning). Refer to the sticker on your driver’s door jamb for the correct PSI — not the number on the tyre sidewall.
- Inspect tread depth. The legal minimum in the UAE is 1.6mm. If you’re anywhere close to that, replace them before summer.
- Look for cracking or bulging on sidewalls, which indicates heat damage or age-related degradation.
Model-specific note: The Toyota Camry (2018–2024) typically runs on 215/55R17 tyres. Popular replacements for UAE conditions include the Bridgestone Turanza and Michelin Primacy lines, which handle heat well. Nissan Kicks owners running the standard 205/55R17 should pay extra attention — the lighter vehicle weight can mask how worn the tyres actually are.
5. Replace Your Windshield Wipers
This one’s often overlooked. UAE sun destroys wiper rubber faster than anywhere else. By the time the occasional summer rain or sandstorm hits, cracked wipers just smear your windshield and reduce visibility.
Good-quality wipers cost between AED 40–100 for a pair. It’s a two-minute job and a worthwhile safety upgrade. If you’re browsing used cars in Dubai, this is one of the first things our inspectors flag during the 200-point check.
6. Protect Your Car’s Paintwork and Interior
UV radiation at UAE intensity breaks down clear coat, fades paint, and cracks leather and dashboard plastics over time. You can’t avoid the sun entirely, but you can reduce the damage:
- Use a windshield sunshade — it can reduce interior temperatures by 15–20°C.
- Apply a ceramic coating or quality wax before summer starts. This adds a protective layer against UV and sand abrasion.
- Condition leather seats with a UV-protectant product every 4–6 weeks.
- Park in shade whenever possible. Covered parking is worth its weight in gold from May to September.
These steps preserve your car’s appearance — and its resale value. If you eventually want to sell your car, well-maintained paintwork and a clean interior make a tangible difference in what buyers are willing to pay.
7. Check All Fluid Levels (Not Just Coolant)
Summer heat affects every fluid in your car. Before temperatures peak, check:
- Engine oil: If you’re within 1,000 km of your next oil change, do it now. Heat thins oil faster, reducing its protective properties.
- Brake fluid: It absorbs moisture over time, lowering its boiling point. If it hasn’t been changed in two years, schedule a flush.
- Power steering fluid: Low levels cause whining noises and stiff steering — especially noticeable in older Honda Accord and Civic models.
- Windshield washer fluid: Use a summer-grade product. Water alone leaves mineral deposits and breeds bacteria.
8. Inspect Belts and Hoses
Rubber components deteriorate faster in extreme heat. A snapped serpentine belt means no AC, no power steering, and no alternator — all at once. A burst radiator hose means immediate overheating.
Ask your mechanic to visually inspect belts for cracking, glazing, or fraying. Squeeze radiator hoses — they should feel firm, not spongy or brittle. On higher-mileage cars (above 100,000 km), consider preventive replacement even if they look okay.
If you’re exploring the Sharjah car market or other emirates for a used car, this is something worth verifying in the vehicle’s service history before purchase.
9. Test Your Car’s Electrical System
Heat accelerates wear on wiring, fuses, and electronic modules. Common summer electrical issues include:
- Flickering dashboard lights
- Sluggish power windows
- Infotainment screen glitches
- Intermittent sensor warnings
If you notice any of these, address them before summer amplifies the problem. A diagnostic scan (OBD-II) at most garages costs AED 50–150 and can reveal stored fault codes that point to developing issues.
Model-specific note: The 2020–2023 Toyota Camry occasionally shows a phantom “Check Engine” light related to the evaporative emission system in extreme heat. It’s usually not serious, but it’s worth scanning to confirm.
10. Plan Your Summer Service Schedule Now
Here’s something most people don’t think about: garages get busier as summer sets in. Everyone waits until something breaks. If you schedule your major service in April or early May, you avoid the rush and get your car ready before it actually matters.
A solid pre-summer service should include:
- Oil and filter change
- AC system service
- Battery test
- Coolant check or flush
- Tyre inspection and rotation
- Belt and hose inspection
- Brake check
Budget around AED 500–1,200 depending on your model and what’s needed. For a standard Toyota Camry service at an independent garage, expect closer to AED 600–800. Honda and Nissan models fall in a similar range.
What If Your Car Isn’t Worth the Repair Bill?
Sometimes a pre-summer check reveals that your car needs more work than it’s worth — an aging compressor, a tired battery, worn suspension bushings, and tyres all at once. If that’s your situation, it might be the right time to consider upgrading.

Frequently Asked Questions
Get it tested at least once before summer starts (April–May) and again mid-summer (July–August). If your battery is over two years old, check it monthly. Most service centres offer free testing. A failing battery in 50°C heat can leave you stranded within days of showing the first signs of weakness.
Yes. Prolonged exposure to direct UAE sun causes clear coat oxidation, which appears as fading or a chalky texture. Once the clear coat is compromised, the only fix is repainting. A quality ceramic coating or regular waxing provides a protective barrier and is far less expensive than a respray, which can run AED 3,000–8,000 depending on the extent.
Follow the manufacturer-recommended PSI listed on the sticker inside your driver’s door jamb. Don’t under-inflate or over-inflate to “compensate” for heat. Check pressure when tyres are cold — ideally first thing in the morning. Tyre pressure naturally increases by 1–2 PSI for every 5°C rise in ambient temperature, which is already factored into the manufacturer’s recommendation.
Absolutely. AC performance degrades gradually, so you may not notice a 10–15% drop in cooling efficiency. A proper service — including refrigerant top-up and cabin filter replacement — costs AED 200–400 and can prevent compressor failure, which runs AED 2,000–5,000 to repair. Think of it as affordable insurance for your comfort and your wallet.
