Role of the coolant
Prevention from being frozen:
When the coolant liquid freezes up, the volume of liquid expands by approx 9%. When a coolant temperature goes down in the winter season, it may destroy the cylinder head and cores of the car engine and radiator respectively due to the excess pressure.
Therefore materials with relatively low freezing points are generally used for coolant liquid. Ethylene glycol is mostly using in current time.
Prevention from getting rust:
Various metal and nonmetal materials are applying for cooling methods. When rust is generated from metal materials, it tends to block the coolant liquid flow in a radiator and the circulation of the coolant and results in the overheat. Therefore the additive with antirust effects is a must to be diluted in the coolant liquid.
Elevation of boiling point effect:
The temperature of the coolant rises gradually in time for driving for a long distance as previously written. Especially recent cars come with downsizing radiators for space-saving purposes in the engine space usually under the bonnet.
It leads to the fact that the temperature of the engine rises faster than before theoretically. As a consequence, the temperature of the coolant becomes higher as well. Therefore raw materials with a high boiling point will be utterly necessary. Ethylene glycol has a boiling point of more than 190 degrees Celsius.
The need for the courant exchange
The main ingredient of the coolant, ethylene glycol has one disadvantage. Therefore the antioxidant to prevent metal corrosion is add in coolant liquid in large quantities. If the heat of ethylene glycol is more, the additive evaporates as well. The coolant system deteriorated by heat and the oxidation progresses in accordance with time.
5 Benefits of changing coolant liquid
Removes Rust and Scale Deposit: Over time rust and scale deposits build up within the radiator of Car. A flush helps to remove these deposits which are pushing out with the old anti-freeze. This is important since these build-ups can cause overheating or even damage your car’s radiator.
Lubricate the Water Pump: The additives in the coolant lubricate the vehicle’s water pump. This will lengthen the life of the water pump.
Removes Contaminants: Flush completely drains the system of the old anti-freeze which means that any contaminants that have made their way into the system will be flushed out as well. The additives in coolant can lose important anti-corrosive properties over time which leads to the buildup of particles. Car radiator flush will remove these particles from the system.
Protect Against Rust and Foam: The new anti-freeze will have additives that help prevent rust and build up. It will also prevent foaming in the system which helps it to operate efficiently.
How much does it cost to fix a coolant leak?
The Green or orange fluid coming from your car may symbolize you have a coolant leak. Fortunately, vividly colored coolant (a.k.a. antifreeze) is very obvious to locate. Nevertheless, reaching the source of the leak may be more difficult to manage.
Your car may have a hole in a radiator pipe or a blown head gasket. Either way, you should have it repair/fixed as soon as possible. Low coolant can induce your car to overheat and cause severe injury to the engine.
When Leaking Coolant:
First, place a slice of cardboard beneath your car and leave it there overnight. Take a glance at the cardboard in the daylight to learn a rough estimation of the area of the car coolant leak.
Then, open the bonnet and inspect for indications of the leak. Examine the radiator tube and clips for symptoms of wetness.
If it’s occurring from the radiator, you’ll need to change it. If the leak is coming from a pipe or hose clamp, you will solely need to renew the hose.
Cause of Coolant Leak:
If you can’t locate the cause of the coolant leak efficiently, there may be another issue at hand. A coolant leak can also be produced by a failed gasket head.
The gasket head is remarkably essential to your car’s engine. It seals the cylinder head to the engine block. Dangerous leaks occurring from a blown gasket head can happen in coolant and oil mixing or total loss of compression, which may cause critical difficulties driving your car.
To determine if your car has blown the gasket head, take a look at the engine temperature gauge. If it’s overheating, it may symbolize a blown head gasket.
Next, use the oil dipstick to examine your oil. If you see froth on the dipstick, it may symbolize that coolant has leaked into the oil. Additionally, view white smoke and water drops arising out of your car’s tailpipe.
Cost of Fixing Coolant Leak:
Unless you have a high-grade deal of knowledge with auto repairs, it’s a good idea to take your car to the mechanic to fix an antifreeze leak. The cost of repairs can reach drastically, depending on the source of the difficulty.
Renewing a blown head gasket can be very expensive. Although the part itself costs about $75, it needs a large number of workers to renew it.
Overall, you could spend $400 or higher for this repair. Renewing a radiator pipe is a fast and simple fix and will only run you from $35 to $65 for the whole repair. A radiator replacement cost about $300 or more, depending on the dimension and type of your car.
Don’t delay when you discover a coolant leak. A few green or orange droplets below your car may seem harmless, but they may symbolize a more substantial problem with your car’s radiator or engine.
