Reasons Why Your Car Is Overheating
It is one of the worst encounters you can ever experience as a driver. You speed up your car as you try to get through the heavy traffic. You look at your watch again and realize that you are now thirty minutes late for that all important meeting that had been planned for weeks. Traffic finally opens up and as you hit the gas pedal, fumes start spewing from your hood as lights go on and off on your dashboard. You get that sinking feeling in your stomach as you realize your car has overheated.
What might be the cause of this unfortunate scenario that catches almost every driver off guard? There are a number of reasons as to why a car might overheat.
A Broken Fan Shroud
A fan shroud is an essential part of the cooling system and needs to be intact when you are driving your car. It helps in funneling the air via the radiator thus maintaining a cool atmosphere in the engine. If your shroud breaks off or cracks, you should replace it as soon as possible.
Reduced Coolant Levels
Your engine will tend to overheat if the coolant level is low. This is one of the simplest errors to fix as you only need to look at the coolant reservoir in the engine and see whether the liquid is below the marked level. If it is, just refill it with antifreeze water up to the required level.
A Faulty Fan Belt
The fan belt is responsible for making the fan propel and pull cooling air into the engine. The belt can snap off and fall due to wear and tear, making the fan to stop working. You might not realize that this has happened, especially if you driving at a high speed because then the air will be forced into the engine through the radiator airflow. It will overheat once you slow down when the air isn't being pushed in anymore.
Blockages on the Radiator Airflow
Sometimes what might be causing your engine to overheat may be a simple blockage on the airflow. The grill on the hood might have blockages such as plastic bags, cotton fluffs, dirt etc. The air can not pass through if the airflow has obstructions. If this is the problem, just get rid of the stubborn debris and you will be good to go.
A Faulty Water Pump
The water pump is an essential part of the cooling system. It ensures the coolant is circulated throughout the engine. A broken pump will result in a leak and there will not be enough fluids left to keep the engine cool and working.
A Clogged Radiator
The radiator can accumulate a lot of dirt and small particles over an extended period of time, more so if the fluid has not been changed for some time. Such an incident will hinder the radiator from working efficiently.
A Stuck Thermostat
The thermostat may be stuck shut or open. When this happens, it will not be able to control the flow of coolant into the radiator at appropriate times, and as a result, the car will overheat.
Lack of Oil
The oil is meant for lubricating all the moving parts in the engine. If a leak occurs, there may not be enough oil to lubricate some of these parts, resulting in lots of friction in the engine. If this problem persists without being corrected, the frictions will result in a build up of excess heat.
Overheating always seems to happen at the worst possible moment. Luckily, you can avoid this occurrence by taking your car for regular check ups. Choose a trustworthy mechanic to be attending to it on a regular basis and let them advice you on how to keep your engine healthy. Take care of your car and it will take care of you on the road.
