Short answer: if the temperature gauge rises or a warning appears, turn the AC off, turn the cabin heater on to pull heat from the engine, pull over safely and switch the engine off. Do not open the expansion tank while hot. The usual causes in Dubai are coolant loss, a failed thermostat or water pump, a blocked radiator face, a failed cooling fan or a head gasket fault.

What to do immediately
- ▸Switch the air conditioning off to reduce load on the engine and condenser.
- ▸Turn the cabin heater and blower to maximum to draw heat away from the engine.
- ▸Pull over safely as soon as possible and switch off the engine.
- ▸Do not open the coolant expansion tank while the system is hot.
- ▸Check for visible steam, coolant on the ground or a shredded belt.
- ▸Arrange recovery rather than continuing to drive, which risks head gasket damage.
How a workshop finds the real cause
A cooling fault should be diagnosed with a pressure test, a thermostat and fan function check, coolant condition analysis and live temperature data from the diagnostic platform. Combustion gas testing identifies a head gasket issue. Replacing a radiator or thermostat without testing often leaves the actual fault in place.
Common overheating causes in Dubai
- ▸Slow coolant loss from a hose joint, plastic housing or radiator seam.
- ▸Radiator and condenser faces blocked by dust and sand, reducing airflow.
- ▸Cooling fan or fan control module failure, most noticeable in traffic.
- ▸Thermostat or water pump failure on higher mileage cars.
FAQs
Can I keep driving a short distance if the engine is overheating?
No. Continuing to drive risks warping the cylinder head or damaging the head gasket, which is a far larger repair.
Why does my car only overheat in traffic?
That pattern usually points to airflow: a cooling fan fault or a blocked radiator and condenser face, since there is no ram air at low speed.
Do you pressure test the cooling system?
Yes. Pressure testing, thermostat and fan checks and live data are used to find the actual cause before any part is quoted.
