1, Stop the car immediately if the temperature warning indicator light up in the meter cluster. Open the bonnet after the car cool down and check if there are dirts attached on the radiator surface which affecting its heat dissipation causing rise in water temperature.
2. Blockage between condenser and radiator also will cause poor heat dissipation on the radiator which lead to high water temperature. Condenser should be taken down and cleaned with chemical and blow dry with compressed air gun. The radiator external surface should be cleaned as well. Please be cautious when cleaning the condenser because the heat dissipation will be affected if the aluminium fins deformed, suggest owner to get assist from workshop.
3. If the above situations is not detected, can check if there is water mark beneath the engine after it is cooled down. Check if the radiator is broken as it may cause coolant leaking and lead to rising water temperature.
4. If the radiator is broken but not severe, may top up some pure water for emergency usage first, then drive slowly to the workshop to repair. If the condition is sever, suggest to contact roadside assists.
Suggest to repair at workshop. The usual keypoints and procedure of repair are:
1. Check if the water hose from radiator is broken or leakage, replace if it is broken.
2. Use professional cleaning chemical to clean the interior and exterior of the radiator, replace if it is faulty.
3. Dismantle the condenser and clean with professional cleaning chemical.
4. Start the car to check if the problem is resolved after repairing done.
