The immediate consequence of driving 10 km without coolant in the radiator is a high probability of severe engine damage, particularly under the UAE's extreme summer conditions where underhood temperatures can exceed 120°C. According to the RTA Dubai's vehicle maintenance guidelines and analysis from the UAE's Ministry of Industry and Advanced Technology (MoIAT) on automotive component failures, an engine running without coolant can reach critical temperatures within minutes, not kilometres. The primary cost is not the 10 km driven, but the engine's exposure to extreme heat stress. For a common GCC-spec vehicle like a Toyota Land Cruiser or Nissan Patrol, this can lead to immediate issues like a warped cylinder head (repair cost: 8,000-15,000 AED) or a blown head gasket (repair: 3,000-7,000 AED). In a worst-case scenario common in desert driving conditions, the engine block can crack or the pistons can seize, necessitating a full engine replacement exceeding 30,000 AED for a V6/V8 engine. The total cost of ownership (TCO) impact is significant; a major overheat event can reduce a vehicle's resale value in the UAE used car market by 35-50% according to market trends. Proactive maintenance, including checking the coolant level every two weeks and using a mix of antifreeze and water suitable for 50°C+ climates, is a nominal annual cost (approx. 150-300 AED) compared to catastrophic failure.
