Engine overheating in summer: causes and fixes
Codes in this article:SPN 110 FMI 0
Gulf summer heat puts heavy load on the cooling system of heavy equipment, and any small fault quickly shows up as high coolant temperature.
⚠️ Never open the radiator cap while the engine is hot. The coolant is under pressure and can cause burns.
Most common causes
- Radiator core clogged with dust and sand.
- Low coolant or a leaking hose.
- Stuck thermostat.
- Loose or broken fan belt.
- Weak water pump.
What to do
- Stop the machine and let it cool.
- Blow out the radiator core with air, from the inside out.
- Check the coolant level and top up with the right coolant.
- Check the fan belt and tighten it.
- If overheating repeats, check the thermostat and water pump.

Weekly radiator cleaning on dusty sites saves you many breakdowns and extends engine life.
