The main reasons for a car's temperature gauge rising, especially during UAE summers with temperatures consistently above 40°C, are leaks in the cooling system, a faulty radiator fan, a clogged radiator from dust and sand, or a failing water pump. Based on common garage repair bills in Dubai and Abu Dhabi, the cost to fix these issues can vary significantly: a coolant leak repair might cost around 500 - 1,500 AED depending on the pipe location, replacing an electric radiator fan assembly can range from 800 - 2,000 AED for a popular GCC-spec sedan like a Toyota Camry, and a water pump replacement, often done with the timing belt, can exceed 2,500 AED for larger engines like those in a Nissan Patrol. The RTA Dubai's vehicle inspection criteria explicitly list cooling system efficiency as a critical check point, particularly before the summer months. Furthermore, data from the MOI UAE's annual road safety reports often highlights engine overheating as a contributing factor in roadside breakdowns during peak summer, leading to secondary risks on highways like Sheikh Zayed Road. For an average car owner, neglecting a minor coolant leak can lead to a complete overheating incident, resulting in potential engine damage (seized engine repairs can cost over 10,000 AED) and significantly higher depreciation. The practical total cost of ownership (TCO) impact makes addressing early warning signs—like the gauge moving past the midpoint—a financially prudent decision.
