How to check for car overheating problems

Car overheating problems are easy to diagnose even if you are not a professional car technician.  This just entails a little knowledge about the different car parts and their functions.  The following are just few of the basic car parts that you should check once you experienced car overheating.

Step 1:  See if there’s coolant or antifreeze leak in the radiator.

To determine if your car has heating problem, check if there is enough coolant or antifreeze in the radiator.  This can be seen by removing the radiator cap only when the engine is cold and then looking at the radiator.  See if the fluid level is at the recommended level.  You should check if the system has any leaks prior to adding more fluid.

Step 2:  Check the thermostat.

The biggest cause of overheating for older cars is the thermostat.  It is a simple device that controls the flow of the coolant into the engine, allowing it to stay and absorb heat and then flow out into the radiator to cool off.  Thus, a broken thermostat can make the engine too cool or too hot.  The most effective solution to this problem is to replace the thermostat.

Step 3:  Examine the fan.

In mechanical fans, the number one cause of overheating problems is the faulty fan clutch.  This reduces the fan’s cooling effectiveness up to 50%, which is dependent on its distance to the radiator.  This can be hot enough to cause the overheating of the engine during hot weather or when it is working hard.  A defective fan clutch is commonly overlooked as the cause of overheating, and so it should be checked carefully.

Step 4:  Inspect the belts and hoses.

In events of overheating, it is important to check for the belt tension and condition A belt that is loosely attached prevents the water pump from circulating the coolant  fast enough, or it also prevents the fan from turning fast for proper cooling.  The state of the hoses should also be checked in cases of overheating.  The hoses should not be over five years old.

Warning:  Sometimes a lower radiator hose will collapse under vacuum at high speed and restrict the flow of coolant from the radiator into the engine.  This can happen if the reinforcing spring inside the hose is missing or damaged.

The principal reason for overheating is caused by the decrease in the cooling system’s ability to absorb, transport, and dissipate heat.  A coolant leak, a defective thermostat, a faulty fan clutch, a collapsed hose, and a loose belt are just few of the many things that you should check in cases of overheating.  It is very important that prior to driving your car, you have geared yourself with the basic knowledge of these parts so you can eventually perform troubleshooting.

  1. Overheating could be the result of faulty wiring/equipment malfunction, lack of proper maintenance or leaks in the pipes. It is a serious problem and a nightmare, especially when this leaves you stuck in the middle of nowhere. Always remember that the saying “prevention is better than cure” not only applies to people, but also to your car’s health. To prevent this from happening to you, make sure that your car is properly taken care of, routinely take it out for maintenance and service checks, make sure that you do not overuse your car, let it rest, one of the leading causes of overheating is a blown-up engine. A result of working the engine harder than it can.

  2. It is probably the most frustrating part of driving a car. Your engine gets so worked up, especially on a humid day. Since you are the driver, you are responsible for observing the behavior of your vehicle. When you have the slightest hint that your car may overheat, it is best to stop the car at the side of the road and check under the hood immediately. It is advisable to treat the overheating before it gets worst. If you checked that the problem is not the coolant level, call up an expert. Do not try to fix it yourself when you are not properly trained for it.

    Regarding the fan system, Does anybody know where in Cebu City can we find surplus Mitsubishi Pajero Cooling fans?
    The lifespan of Class A imitations is only 6 months. So, its better to install the original.

    The radiator must be checked for rust and leaks. Rust can clog up the hose that connects the radiator to the engine and when it clogs up, the engine will overheat.
