The job of your vehicle's cooling system is to circulate coolant through the engine to absorb heat generated from combustion and friction. It then transfers this heat away from the assembly to the radiator, where the heat is allowed to dissipate. Once the coolant releases the absorbed heat, it flows back to your engine to repeat the cycle. This helps prevent the assembly from overheating.
When coolant begins to leak, your engine is placed at risk since less fluid is available to transfer heat away from it. Thus, it is important to locate the source of the leak so it can be fixed before serious damage results. In this article, we'll describe several places under the hood where such leaks can form. You'll discover that some areas are much easier - and less expensive - to address than others.
Radiator Hoses And Heater Hoses
These hoses are made of rubber, and thus will corrode over time. Unless they are replaced on a regular basis, cracks will start to develop. Depending on the size and shape of the cracks, coolant might spurt from them. In most cases, however, these fissures will only open once the temperature rises inside the hoses. Many drivers fail to notice them for this reason.
Inspect these hoses once a month to make sure cracks have not formed. Because splits in the rubber may be difficult to see, it is useful to squeeze the hoses. If cracks have developed, install replacements.
Your vehicle's heater core is located under the dashboard. Most people are unaware that coolant goes through this unit before circulating back to the radiator. There are two heater hoses from which fluid can leak, though leaks can also develop inside the core. Even though this component is virtually hidden, you'll be able to see the effects of coolant seepage almost immediately. The fluid usually drips to the floor on the passenger's side.
Water Pump Seal And Gasket
Inside the water pump's housing, impellers spin underneath the shaft seal. This seal can develop a leak through which coolant will seep. Also, the housing is separated from the pump mounting surface by a gasket. This gasket can become worn, and develop a leak.
Water pump problems are best resolved by replacing the component since even minor issues are difficult to repair.
Blown Head Gasket
One of the most common reasons for a coolant leak inside the engine (as opposed to leaks in the hoses, heater core, and water pump) is a blown head gasket. This component sits between the engine block and cylinder head. The problem here is that leaks are not always evident. When coolant seeps through a blown head gasket, it leaks into the cylinders and crankcase. The former will produce white smoke from your car's tailpipe. The latter may produce no perceptible signs at all.
The solution is to replace the head gasket, an expensive job since it requires separating the block and cylinder head.
Coolant leaks can develop in a few places within the radiator, including the core and end tanks. Most of them, however, occur where the upper and lower hoses connect to the assembly. Not only can the hoses deteriorate over time, but leaks at the connections develop due to the hoses coming loose. This can happen as a result of bumpy rides and constant vibrations. Tighten the connections to seal the leaks.
Engine Block And Cylinder Head
The block and cylinder head can develop cracks that allow coolant to escape through them. Here, the effects are similar to those that result from a blown head gasket. Specifically, coolant can enter the cylinders and crankcase. Not mentioned earlier, seepage into the crankcase can cause damage to the bearings. Leaks into the cylinders can damage the pistons, and lead to problems that increase emissions. This will force your catalytic converter to work harder than it should, potentially causing it to fail prematurely.
