The cooling system in the car plays a very vital role to the proper functioning of the car’s engine and sometimes coolant leaks can tamper with the car’s efficiency and effectiveness. The car’s coolant system works by circulating a coolant and water mixture under pressure through pipes and hoses through the engine and radiator, then cooling the engine. The temperature of the coolant increases as the car runs and the coolant is expanded making any excess coolant in the system move into the reservoir tank through rubber hoses. However, when this system isn’t working well, there is the risk of running into major repairs. Thus try and fix a coolant leak as soon as the show up to avoid crucial issues.
KNOWING THE LEAK
There are actually some common causes of coolant leaks, although different kinds of leak have different possibilities that vary in severity. If there’s a sign that coolant has collected on the ground under the car or the reservoir tank is not at the level it should be. This could signal a slow leak in your cooling system. An abrupt engine overheating is also another major tip-off that may be a coolant leak. It is possible to smell the leaking coolant. Most times, the kind of leak is easy to determine but other times it takes a little more effort to see it. Thus it becomes imperative to check the level of the coolant reservoir tank often. Below are some of the most common causes of coolant leaks:
1 LEAKING RADIATOR LID
If the radiator lid is weak or leaking, there is bound to be experiences of loss of coolant from the overflow hose each time the coolant is heated up. The radiator is a pressurized unit so if there is pressure loss from the lid, the pressure will be lost and there would be a leak. This can be checked with a pressure test of the radiator lid. For lid specification, Refer to your car’s manual.
2 INTERNAL LEAKAGE
An internal leak won’t drop off under the car. But, becomes noticeable when the coolant level keeps dropping and there would be a continuous need to constant refill the reservoir tank to avoid engine overheating. An internal leak is most often caused by a leakage in the head or clogging or and a leaking head gasket which allows the escape of coolant from the system.
3 EXTERNAL LEAK
External leakages are the types most easily seen and diagnosed. In very many cases, when the coolant escape the car engine quickly overheats. It is even easy to spot where the leak is issuing out of by inspecting it; a broken hose or a hole in the radiator are examples. Additionally, Leaks in water pump, heater core and engine freeze plugs can equally allow escape of coolant. These are simple too diagnose by inspection.
There could be a crack in the coolant reservoir. However since the coolant in the main system is what cools the engine, this condition is less likely to cause the car to overheat, however in this kind of case, there will likely be coolant droppings under the car when it is parked for long a time.
