UAE Summer Car Care: Six Essential Checks to Prevent Breakdowns in Extreme Heat

With temperatures soaring across the UAE, automotive experts are urging motorists to carry out regular vehicle inspections to prevent overheating, battery failures and costly repairs during the summer months.

Mechanics say that while modern vehicles are designed to withstand high temperatures, prolonged exposure to extreme heat places significant strain on key components, including the cooling system, battery, tyres and engine. Routine maintenance and early detection of minor issues can help drivers avoid unexpected breakdowns.

The advice comes after Dubai resident Abdul Aziz, an engineer, noticed a burning smell while driving home from work. After taking his vehicle to a nearby garage, mechanics discovered the coolant level had fallen below the minimum mark—an issue that could have resulted in severe engine overheating if left unattended.

According to mechanics, similar cases become increasingly common during the UAE summer, with many problems beginning as small faults before developing into major mechanical failures.

Six Summer Maintenance Checks Every Driver Should Make

1. Monitor the Cooling System

Mechanics say the cooling system is the most critical component during hot weather. Drivers should regularly inspect coolant levels and never ignore signs of coolant leaks.

A blocked radiator caused by accumulated dust and sand can also reduce cooling efficiency. Cleaning the radiator periodically helps maintain proper airflow and engine temperature.

2. Check for Leaks Under the Bonnet

Experts recommend inspecting the engine bay at least once a week for signs of coolant, engine oil or fuel leaks, as well as cracked hoses or damaged wiring.

Minor leaks can worsen rapidly in extreme temperatures, potentially leading to expensive engine repairs if left untreated.

3. Test the Battery

High temperatures significantly reduce battery life in the UAE.

Mechanics advise having the battery tested if it is more than three years old, particularly before or during the peak summer season, to reduce the risk of unexpected breakdowns.

4. Check Tyre Pressure When Cold

Tyre pressure naturally increases as temperatures rise.

Drivers should check tyre pressure early in the morning before driving and ensure it matches the manufacturer's recommended levels to improve safety, handling and tyre lifespan.

5. Inspect Belts, Hoses and Electrical Wiring

Rubber belts and hoses become brittle over time, while damaged electrical wiring can pose serious risks during hot weather.

Vehicle owners should inspect hoses for cracks and ensure wiring remains secure, particularly in vehicles fitted with aftermarket electrical accessories.

6. Clean the Radiator and Engine Bay

Dust, sand and debris can accumulate quickly inside the engine compartment, restricting airflow and trapping heat.

Regular cleaning of the radiator and removal of leaves, plastic bags or other debris from the engine bay can improve cooling performance and reduce heat build-up.

Early Checks Can Prevent Costly Repairs

Automotive experts stress that motorists should not wait until their next scheduled service to inspect their vehicles.

Simple visual inspections carried out regularly during the summer can identify minor problems before they develop into major mechanical failures, helping drivers save both time and repair costs.

Mechanics also advise motorists to pay attention to warning signs such as burning smells, rising engine temperatures, steam from the bonnet or unusual dashboard alerts, as these often indicate developing issues that require immediate attention.
