Summer breakdowns in the UAE cluster around cooling systems, and the pattern is predictable. A cooling system that was marginal in February, a slightly weak water pump, an ageing radiator fan, coolant a year past its change, has no headroom left when ambient temperature passes 45 degrees and the AC condenser is dumping its own heat in front of the radiator. Stop-start traffic is the killer, because airflow through the radiator drops to whatever the fans can pull. If the temperature needle climbs past its normal mark, turn the AC off, turn the cabin heater on full, which sounds absurd but bleeds engine heat into the cabin, and get off the road at the first safe opportunity.
What a kerb-side visit cannot fix is the damage overheating causes when ignored: a warped head or failed head gasket from driving on while the needle sat in the red. White exhaust smoke, coolant in the oil showing as a milky residue under the filler cap, or continuous bubbling in the reservoir are the signs the engine has crossed that line, and at that point the correct spend is a flatbed, not more coolant. This is the scenario where a cheap decision, driving one more exit, becomes a five-figure engine bill.
