![]() ![]() The coolant temperature sensor or CTS has a sensing probe and an electrical connector. #Coolant leak sealer update#The data is also used to control the radiator fan and to update the temperature gauge on the driver console. Some engines have more than one coolant temperature sensor. The ECU will use this data to manage fuel injection and ignition time. The coolant temperature sensor has a main function to monitor the engine temperature. This allows the cold coolant from radiator to flow to the engine side, and the hot coolant from engine side to flow to the radiator. When the coolant reaches a temperature between 160 and 190 Fahrenheit, the bypass valve closes and the main valve opens. Once the engine heats up, so does the coolant. This helps the engine to heat up to operating temperature quickly. The bypass stays open when the engine is cold so the coolant can pass through the radiator and recirculates through the engine. The thermostat main parts are: frame, charge cylinder, main valve, main spring, bypass valve, and secondary spring. It will always be covered in the coolant so that the temperature can be sensed. The thermostat is basically a valve which has a main function to regulate the flow of the coolant and ensures that proper operating temperature of the engine is maintained. In case if there is too much pressure buildup in the system due to trapped air or other failures, the coolant in the expansion tank will be pushed out through the overflow hose. When the system cools down, the vacuum inside the system sucks back the coolant from the expansion tank. When the pressure inside reaches above 15 PSI, the pressure cap valve is activated and the coolant flows to the coolant tank until the pressure gets to a normal level. The radiator cap consists of a spring-loaded valve mechanism which will respond to higher pressure. ![]() Here comes the role of the radiator pressure cap. #Coolant leak sealer how to#Heating liquid inside a closed system always builds up pressure, so how to maintain the pressure? The pressure cap plays a vital role in the cooling system. The radiator consists of an inlet port, outlet port, a drain plug, and a radiator pressure cap. The radiator acts as a heat exchanger and is used to transfer the excess heat created by the engine into the atmosphere. The serpentine belt also drives the power steering pump, alternator and AC compressor. The impeller is driven by the engine drive belt through a pulley. The pump consists of an impeller, a pulley flange, and an O-ring. The water pump is the heart of the cooling system which pumps the coolant through the system with the help of the radial impeller which is driven by a serpentine belt. 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: 1. A lot of heat is generated due to the combustion gas and the friction of mechanical parts. Main Cooling System PartsĪ car engine is basically an internal combustion engine where power is generated through the expansion of high-temperature and high-pressure gases. Is your engine oil due for a change? Visit our Car Fluid Guide Website to learn the importance of changing your oil on time, which type of engine oil is best for your vehicle, and much more. If you are unable to locate and repair your coolant leak, make sure to take your vehicle to the mechanic shop and get it repaired as soon as possible. Make sure to locate and repair the coolant leak before your engine overheats. Don’t risk overheating your engine.Ĭonclusion: It is not safe to drive with a coolant leak because you need coolant to keep your engine from overheating. If the leak is too great, call a tow truck. So, if you notice any leak coming from the cooling system, make sure to take your vehicle to the mechanic and get it repaired. This will result in engine overheating.Īn overheated engine costs a lot to repair. If there is even a slight leak in the cooling system, the coolant will leak out and there would be no coolant left to remove the excess heat from the engine. ![]() The cooling system is in charge of removing the excess heat from the engine and keeping the engine at operating temperatures. But, if treated on time, you can avoid some big repair bills. Have you ever had a coolant leak and you just ask yourself is coolant leak normal or is coolant leak dangerous? Is it safe to drive with a coolant leak? The coolant leak can never be a good thing.
