So, cooling system problems can start at any time. But, always seem to come at the worst times. For instance, you may be driving down the road or sitting at a stop light; when you first notice; the temperature gauge in your vehicle starting to climb. But, if you let it go long enough; you may notice steam coming from under the hood. As a result, indicating that the engine is overheating.
So, if you feel your vehicle has a cooling system problem; knowing what to look for; can assist you in identifying the issue; and even help you repair it yourself. So, The cooling system in your vehicle is designed; to keep the engine at a consistent temperature. As a result, it keeps the engine from running; too hot or too cold once it is warmed up.
So, the cooling system consists of several main components; that each perform a different task.
Each of the following components are essential to keep the engine; running at the correct temperature:
- Radiator
- Water Pump
- Freeze Plugs
- Head and Timing Cover Gaskets
- Heater Core
- Thermostat
- Hoses
- Fan Clutch
- Electric Cooling Fan
So, most vehicles now employ an expansion tank; that allows the coolant to expand. Also, to exit, the cooling circuit when hot; and to return when the engine cools. Furthermore, The cooling system also incorporates elements of the cabin’s ventilation system.
Recap
So, the cooling system works by, pushing coolant through the passages in the engine block. Firstly, the coolant is pushed through the engine block. In addition, as the coolant travels through these passages, it absorbs heat from the engine.
Next, this heated coolant travels to the radiator; where it is cooled by the air stream entering the grille of the car. The coolant is cooled on its travels through the radiator; returning once again to the engine; to pick up more of the engine’s heat and carrying it away
So, there is a thermostat between the engine and the radiator. The thermostat regulates what happens to the liquid, depending on the temperature. If the liquid’s temperature falls below a certain level; the solution bypasses the radiator and instead is diverted back to the engine block.
