How long does the coolant last? -Engine running (1)

Your car's cooling system is built around a coolant that circulates through the system. Most people know that coolant is added through the radiator and that the radiator needs to be full. However, there are times when the radiator doesn't fill that little line on your neck. This means that the refrigerant does not live forever. Read on to find out how and why your car's coolant level gets low.

The need for coolant

Combustion engines must have cooling systems. Most designs use a radiator filled with an antifreeze mixture of ethylene glycol and water designed to remove heat from the engine. The automotive cooling system consists of two main parts: the liquid cooling part and the air cooling part. Both parts of the cooling system must rely on air to some extent, but only one part uses liquid. Older cars often have air cooling systems, while some newer models use air. However, most newer models use liquid cooling.

The liquid cooling system is more complex than air. The coolant is typical of an antifreeze composed primarily of ethylene glycol. There are passageways in the engine block and also in the heads of the engines. A water pump circulates itCoolant (see Amazon), which is moved by hoses and cools in the radiator. Coolant travels through engine parts and absorbs heat.

The heated coolant reaches the radiator through rubber hoses. Natural air drawn through the grill cools the coolant as it flows through the radiator. The coolant is then returned to the engine and the process begins again. The radiator cap regulates the pressure in the cooling system. A thermostat that regulates the temperature of the coolant. The engine will definitely overheat due to lack of antifreeze or antifreeze leaks or lack of circulation.

If there are no problems in the cooling system or elsewhere that could cause premature coolant loss, the coolant should last 3 years. That is, when the coolant is mixed with tap water. If the coolant is mixed with distilled water, the coolant can last about 5 years.

Causes of coolant loss in the car

cause several thingspremature loss of coolant. The problem can arise almost anywhere under the hood. The refrigerant lines could be clogged, or there simply isn't enough refrigerant circulating through the system to keep everything cool. Most vehicles are equipped with a low coolant light to alert the driver when the coolant level is low. These are the most common causes of coolant leaks in internal combustion engines:

Extreme heat– The motor gets very hot and ejects the liquid. When the coolant contains air, it does not absorb heat from the engine in the same way. When temperatures under the hood get extremely high, the coolant begins to evaporate. These things will likely only happen if your radiator fan isn't spinning. Or it could be that the coolant evaporates naturally over time. However, under normal operating conditions you should be able to keep the coolant at maximum.

coolant leaks– Refrigerant can escape from the system in various ways. When the engine heats up, the volume of coolant in the hoses and in the engine expands. Overflowing coolant collects in the expansion tank. The expansion tank hose can become worn or damaged. These problems promote blown head gaskets, engine overheating, and leaks that cause serious damage to the engine and fuel systems. Leaks can occur at the heater core, radiator, thermostat housing, freeze plug, or head gasket. Several other things cause and contribute to refrigerant leaks. The air conditioning compressor is designed to prevent refrigerant from leaking while under pressure. As the air conditioning compressor wears out, the bearings will be damaged. The coolant can then seep through the bearings.

Damaged seal or gasket- The internal combustion engine uses many types of gaskets and seals to keep fluids, including coolant or oil, contained and moving. Many of these gaskets and gaskets are used in the intake manifold and throttle body. Over time, seals can wear out, dry out and leak. Combustion gases from the cylinders enter the cooling system and cause bubbles. The head gasket is a special gasket that sits between the engine block and the cylinders. If this gasket is damaged or burned out, it will cause leaks under the exhaust manifold.

Defective central radiator pipes– If the vehicle's cooling system has not been serviced for a while, old fluid will settle and collect dirt or sludge and even rust, which over time will block the core or grid. Radiator fins corrode and coolant leaks. The engine requires constant coolant flows. If leaks are not fixed in time, the radiator will be permanently damaged. It can also cause head gasket or cylinder head damage, often characterized by radiator damage, engine overheating, and coolant reservoir bubbles.

Heater control valve defective– The heater control valve allows coolant to flow from the engine to the heater core. When the heater control valve is open, heated engine coolant is allowed to flow into the heater core to generate warm air through the vents. If the valve fails, the refrigerant escapes. The valve wears out over time and starts to crack. The coolant flows through the gap.

Blocked radiator core– If your car's cooling system has not been serviced or flushed for a long time, old fluid will build up deposits and rust that will eventually clog the core or grille. Radiator fins corrode and coolant leaks.

You treat your car like shit– If you do not take care of the components in your car, you can cause the failure of various components, which can lead to coolant problems. Maintaining your vehicle is a crucial process that should be done by every car owner and it prevents you from facing many problems. A lack of care with just one component can trigger a domino effect that can also be felt in other areas of the car.

If you want to avoid coolant or other problems and save $100 that you spend at the auto repair shop, you need to have your vehicle checked frequently. You can use oursCar maintenance and repair manualin order to do this. It's basically what mechanics use to check your vehicle to see if there are any issues that need fixing. As soon as they spot the slightest problem they'll ask you to shell out some money, even though it's a problem you can fix yourself in minutes - the manual will teach you how to service your vehicle every few thousand miles, and it will. teach you how to fix minor problems that mechanics have to pay you to fix; You save money in the long run.

Many of our readers have the car repair and maintenance manual printed on their garage wall and 92% of them haven't visited the auto shop in the last year because they know what to do to avoid problems. All you need is to give your vehicle a little care every few thousand miles and you'll never be spending money at the garage again.

Car coolant loss symptoms

If your car is losing coolant, there are a few signs. It is extremely important that you look for these signs and find the leakage problems early on. These are the most common signs that your car is losing coolant:

hot temperature indicator– If the cooling fan is not working, the temperature gauge may be too hot. The coolant stops getting colder as it circulates through the engine and the thermostat recognizes the change. The temperature gauge on your dash will move toward HOT and stay there until you turn off the car.

coolant on the floorIf your engine is overheating, it may mean you need to add more coolant. The leak can collect in puddles of green liquid under your car. (Coolant can be different colors depending on the manufacturer. If there is coolant on the floor under your vehicle, it could be because it has gotten too hot, coolant has overflowed, and it has spilled from the coolant overflow tank. It could also mean that you they have a coolant leak that caused the engine to overheat.

sweet smellIf there is a coolant leak, you will smell a sweet smell under the hood. You can actually smell it while driving and after driving. That's the toxic ethylene glycol running through your cooling system. However, the leak has yet to be found. When you smell the sweet smell, there are problems that will escalate if you don't fix them.

Hot smell under the hood -Less coolant means your car is more likely to overheat. If your vehicle smells hot for a while after you start it, or you smell it when you get out, there is a problem with the cooling system. When the engine overheats, the metal, rubber, and plastic components give off a distinctive odor that many refer to as a "hot smell." The odor can also enter the vehicle through the air conditioning vents.

This is how you save coolant

When it comes to vehicle maintenance, there are a few things that can conserve coolant, or at least minimize its loss. It is therefore very important to have your vehicle serviced regularly. If you have the tools and the skill you might be able to fix it yourself. What you can do to avoid refrigerant loss:

Park in a cool place– The coolant has a certain water content, so it can evaporate. The parts under your engine can get hot even when you are not driving. If you live in an area with scorching heat, find a cool place to park your vehicle so it's cool when you drive away.

Bleed the cooling system- Some problems mean that you simply have to start over. There are several methods to restart your cooling system. This method is the bleed screw method of bleeding the cooling system. To use this method, follow these steps:

  1. Park your car in a safe place.
  2. Make sure your car is turned off and wait for the engine to cool down.
  3. Carefully remove the radiator cap.
  4. Check that the coolant is at the recommended mark. The radiator should be filled to the lower mark on the neck. If there isn't enough coolant, add more to bring it to the mark. The radiator should be filled to the bottom of the radiator neck.
  5. Now fill some coolant into the reservoir. The coolant level in the reservoir should be "cold".
  6. Replace the radiator cap.
  7. Locate the bleed screw on the engine. Once you find it, before removing the bolt, slide a pan under the vehicle to catch any liquid that spills out when you remove the bolt.
  8. Start your car.
  9. Let the car idle for at least 20 minutes to allow the engine to warm up to operating temperature. Feel the radiator hose at the end of 20 minutes to see if it feels hot.
  10. When the hose is hot, remove the bleed screw by slowly turning it counterclockwise with a wrench.Just turn the bleed screw, don't remove it all the way or you could be badly burned by the boiling coolant.
  11. When all of the coolant has entered the sump, tighten the bleed screw.
  12. park car andWait at least 15 to 20 minutes for it to cool.
  13. Top up the radiator with the correct amount of new coolant. Fill the radiator to the same mark at the base of the radiator neck. If necessary, add some coolant to the reservoir.

Get help from certified professionalsRefrigerant evaporation or refrigerant leaks are no small matter. If you ignore this, your car repairs can quickly become expensive. Many cooling system problems cannot be solved with a little patching. Certified technicians know how to replace your coolant or properly maintain your cooling system.
