Car Radiator Water Often Decreases and Causes Hot Car Engine, Check the Following Components

Your Engine's Cooling System - BlueStar Car Inspections

You must know that the radiator is one of the components of the cooling system in the vehicle that functions to cool the engine performance of the car. Some problems in the cooling system we often encounter one of which is a brownish car radiator water.

 Maybe Sahabat Garasi has complained about why when draining water in the reservoir tube is always brownish like there is a rust content from iron. Is this an indication of damage to one component of the cooling system?

Radiator Water Colored Brown

The cause of the radiator water is brown, possibly it could be due to some of the components of the cooling system being rusty. The water in the radiator circulates in the engine through the water mantle. if the radiator, engine block or other components rust it can cause the water to turn brown. then how to solve it if this has happened.

The solution to overcome the brownish radiator water can be by draining the car radiator regularly. Clean the cooling system components using a radiator flush that is widely available in the market. But other than that, the radiator cannot be added with water carelessly, my friends, because if it is not a solution it will cause serious damage.

Car Radiator Water Runs Out Fast

In addition, there are several causes that may make the car radiator water run out quickly. Anything? Come on, see the explanation below.

The car radiator water cap is broken

One of the things that causes the decrease in car radiator water is due to the weakening of the cap pressure on the radiator. Usually this is due to damage in the rubber on the radiator lid that can make water run out faster than usual.

Because the car radiator water cap has started to weaken, of course it will make the water flow faster to the spare tube, even before the pressure valve opens. To fix this, of course you have to replace the radiator cap rubber with a new one.

Leakage on the water pump component

Water pump is a component that functions to pump and circulate water in the engine. If there is damage to this component, it will cause a drastic decrease in the volume of radiator water. Even the leakage caused will be very large, because the flowing water will be quite heavy.

Because the leakage is quite heavy, if it is not repaired immediately, it will cause the engine to experience hot temperature conditions. Usually the damage to this component is due to the age of its use which is too old and exposed to water immersion, making it porous and corroded.

To fix this, of course you have to do proper maintenance such as draining the car radiator water every two months to avoid rust deposition. In addition, use quality water for maximum water pump performance.

Leaks in the car radiator water component fins

Leaks that occur in car radiator water fins are usually not easily visible due to several things, such as being dry or evaporating before the water drips. However, this is one of the reasons for the reduced radiator water. For that check regularly on these parts, so that if there is a leak in the radiator tube of the car can be overcome immediately.

Car radiator water gap

Another cause of a drastic decrease in radiator water is usually due to the lack of tightness of the hose attached to the car radiator components. The gap makes it easy for water to come out of the gap between the hose and the iron radiator. Of course, to overcome this, friends must close the hose on the radiator so that no gaps occur that make a leak in the radiator.

Car radiator water drain cover is not tight

If the leak still occurs after you check the points previously explained, then try to check the cover on the radiator water drain at the bottom. Usually this cover is a little less dense so that the radiator water decreases slowly.

Mineral radiator water, AC, or coolant. Which one is better?

Groundwater or mineral water is often used to fill radiators. Mineral water is indeed more practical and efficient than using coolant radiator water because the price is relatively more expensive on the market. However, are all fluids suitable for filling a car radiator?

As described on the How Stuff Works page, the radiator workflow starts from the coolant being pumped into the cylinder wall. This liquid absorbs and transfers heat out of the cylinder wall, to be cooled in the main tube of the car radiator water reservoir.

From the engine area, the coolant that has been contaminated with hot air moves towards the upper tube of the radiator water through the opening of the thermostat valve, which is the screen between the engine and the radiator. The new thermostat valve opens when exposed to hot air — about 195 fahrenheit (90 degrees Celsius). A malfunction of the thermostat that doesn’t open can be the culprit of the overheating problem because hot fluid from the engine can’t flow to the radiator.

The fluids that carry hot air have high air pressure. So that the condition of the radiator cap must have a pressure safety valve so that it can withstand the push from the air pressure when the liquid has entered the tank above the radiator.

Ground water or mineral water cannot work as effectively as a radiator coolant to cool the engine. This is because the coolant radiator is specially formulated to absorb heat and prevent corrosion (corrosion) of the engine cylinder material. The main content of the coolant, namely water without minerals, anti-freezing agent propylene glycol, and rust prevention.

The propylene glycol content makes radiator fluids have a higher boiling point, as well as a lower freezing point than ordinary water. The high boiling point prevents the coolant from evaporating when it comes into contact with the high temperature of the vehicle engine. The service life of a coolant radiator containing propylene glycol is about two years or 48 thousand kilometers.

It is enough to be able to answer your worries about radiator water that is brown in color, or radiator water that runs out very quickly and a liquid that is suitable for your vehicle’s radiator, right! Hopefully the information above can add to your insight about this one component.
