Hyundai Starex Engine Overheating – Causes & Overhaul Solutions
In the Hyundai Starex, the low-speed radiator fan usually activates when coolant temperature reaches around 94°C. Overheating can start at 110°C, so it's crucial that the cooling fan works on time to keep the engine temperature under control.
Why engine overheat when driving uphill?
Overheating common happens especially when driving uphill, to drive on uphill, engine is working heavier load and produces more heat. You may notice the temperature gauge rise slightly higher compared to driving on a flat road. In such conditions, the radiator fan needs to run faster, run for a longer time to maintain a safe engine's temperature.


Maintaining Your Hyundai's Cooling System
To prevent overheating, every part of the cooling system must be in top condition:
- Radiator: free from clogs and allowing smooth coolant flow
- Water pump: circulating coolant efficiently
- Thermostat: opening at the correct temperature
- Coolant hoses: in good condition to handle pressure
Our comprehensive Hyundai engine overhaul service addresses all these components to ensure your vehicle runs at optimal temperature.
