Engine overheating is a common problem you may face while driving, especially in the UAE summer. Ignoring it can destroy the engine completely. Therefore, here we explain the main causes, what to do straight away when the gauge rises, and how to stop the problem coming back.
Causes of engine overheating
The most common causes are linked to the cooling system itself. For example:
- Low coolant level: there may be a leak in the cooling system, or the coolant may need topping up.
- Problems with the fan or the thermostat: if the fan is not working properly or the thermostat is faulty, the temperature can rise.
- A blocked radiator: dust or debris can block the flow of air and coolant through the radiator.
- A weak water pump: when the pump weakens, the coolant does not circulate fast enough.
A damaged radiator cap can also let pressure and coolant escape. In addition, running the AC in traffic increases the load on the cooling system.
What to do when the engine overheats while driving
First, turn off the AC and turn the heater on to the highest setting to draw off some of the heat. Second, pull over in a safe place as soon as possible and switch off the engine.
However, never open the radiator cap while the engine is hot. The coolant is under high pressure and can cause serious burns. After that, wait until the engine has cooled completely before checking the coolant level.
On the other hand, do not keep driving with the gauge in the red zone. It can damage the cylinder head or the head gasket, which is an expensive repair.
Solutions to stop the problem coming back
The fix depends on the cause, but there are some basic steps:
- Check the coolant level and top it up with the recommended type if needed.
- Check the condition of the fan and the thermostat, and replace them if there is a problem.
- Clean the radiator regularly to make sure it is not blocked.
- Inspect the hoses for cracks or leaks.
In addition, replace the coolant at the interval given in the car’s manual. Old coolant loses its ability to cool the engine and to protect the metal from rust.
When should a specialist inspect the car?
If the problem continues after these steps, have the car inspected by a specialist mechanic. Do the same if you notice white smoke from the exhaust, or a constant loss of coolant with no visible leak. In this case, engine overheating may be linked to an internal problem.
Therefore, we recommend a computer car inspection to read the temperature sensors and any stored faults. In the end, dealing with engine overheating early saves you from expensive repairs. The team at Jordan Car Inspection Center in Sharjah is happy to help.
