Seven reasons why your car will overheat and leave you stranded

Seven reasons why your car will overheat and leave you stranded

Have your ever wondered why your car is likely to leave you stranded with an overheated engine? Every vehicle has a cooling system comprising of several component that enables the car engine & transmission work properly & remain within stipulated operating temperature. A failure of any of the components can leave you stranded on the road and at any time thereby subjecting you to other road hazards like robbery & vehicle vandals.

Today we shall be looking of those components that make up the cooling system which you must maintain to avoid vehicle breakdown.

1. Engine Fan.

The job of the engine fan is to draw cool air from the atmosphere & direct that air towards the engine radiator. This works by cooling the coolant that runs through the radiator which is then circulated into the engine block to help reduce the heat. Excess heat can degrade internal engine component leading to untimely wear & tear. The engine fan can become defective in different forms. The fan might fail completely or become less active in terms of the amount of air it draws from the atmosphere. The moment any of this happens; you will have to have your fan replaced.

2. Radiator.

The radiator is an integral part of your cooling system as it helps circulate coolant into the engine & brings it back to be cooled by the fan. A radiator could be defective in different forms. It may get clogged up with dirt as a result of the quality of coolant or water that goes into it. It may also have a leakage meaning when the engine gets to operating temperature the coolant/water will evaporate leaving the starving the engine of adequate water to cool down; hence you have an overheated vehicle. It is important to observe & lookout for leakages before you start your vehicle or whenever you approach your car on a parked position.

3. Failed Water pump.

Mordern automobile engine are equipped with water pump responsible to pumping & circulating the coolant around the engine. A failed water pump may allow water into the combustion chamber leading to catastrophic damage to the engine & it may be completely damaged that it won’t be able to spin meaning water cannot circulate. This will allow excess heat buildup thereby leading to overheating.

4. Insufficient Collant or No collant.

Insufficient or no Collant at all will definitely lead to overheating. Meaning that the engine does not have adequate water to cool it down. Insufficient Collant can be caused by leakages either from the radiator or from pipes & in some cases a blown or flat head gasket.

5. Radiator cap/cover.

A damaged radiator cover will allow water evaporate when vehicle has reached operating temperature which will lead to insufficient coolant in the engine.

6. Worn head gasket.

A damaged head gasket will often lead to overheating. Engine coolant will always dry up & in some cases may leak into the engine as well. One of the signs of damaged head gasket is rattling noise when accelerating especially when the engine is under load (Turned on Air Conditioner or Hill climbing).

7. Failed Oil Pump.

The engine oil in vehicles also act as cooling agents for the engine. A failed oil pump will also cause an engine to overheat. In some cases, if the engine is clogged up oil won’t circulate properly even if the oil pump is in other.


Someother reasons your car could overheat may be as a result of a blown fuse which may deactivate the operation of the fan.
