What is the purpose of coolant in a car?
The coolant (which is a mix between antifreeze and water) is a liquid which travels in inside the cooling system hoses and pipes and has a function to remove the excess heat from the engine and keep it from overheating.
What is coolant temperature sensor?
The coolant temperature sensor has a main function to monitor the engine temperature. The ECU will use this data to manage fuel injection and ignition time. Some engines have more than one coolant temperature sensor. The data is also used to control the radiator fan and to update the temperature gauge on the driver console.
How does a car engine work?
A car engine is basically an internal combustion engine where power is generated through the expansion of high-temperature and high-pressure gases. A lot of heat is generated due to the combustion gas and the friction of mechanical parts. For sustained operation, these excess heat should be removed from the engine and kept at operating temperature. Here are the main cooling system parts and how they work:
What is the role of a radiator?
The radiator acts as a heat exchanger and is used to transfer the excess heat created by the engine into the atmosphere. The radiator consists of an inlet port, outlet port, a drain plug, and a radiator pressure cap. The pressure cap plays a vital role in the cooling system. Heating liquid inside a closed system always builds up pressure, so how to maintain the pressure?

This is why fixing coolant leaks, is one job that you can’t ignore. 1. Hoses. A car’s coolant system has at least four hoses or aptly the fluid pipes.
What to look for when coolant is leaking?
2. The Radiator Cap. A bad radiator cap is another thing to look for when you find coolant is leaking is from the car’s bottom. Whenever the coolant would heat up, it would overflow from the radiator’s end. The radiator works on the principle of pressure, and this pressure is stabilized with the help of a cap.
How many hoses are needed for coolant?
1. Hoses. A car’s coolant system has at least four hoses or aptly the fluid pipes. The hoses are installed such that they carry the coolant to and fro the radiator. Over time or due to immense heat, there may emerge a case where these hoses develop cracks. The cracks may further lead to developing of leak points.
Why does my head gasket leak?
Owing to the head gasket’s large surface area and due to exposure to temperature variations, they may develop leaks. If the coolant is leaking from the exhaust or the intake manifold, a blown gasket head could be the reason. One should know that treating head gasket leaks should be a priority as they may expand over time.
How does a radiator work?
The radiator works on the principle of pressure, and this pressure is stabilized with the help of a cap. When the cap isn’t fit properly, the pressure will not build up thus the loss of coolant. One needs to keep in check the pressure when diagnosing the reason for the leak.
