Antifreeze for car

Why is antifreeze used in cars? Does antifreeze mix with coolant? What is antifreeze made of? HOAT (Hybrid OAT) – Silicates and organic acids – Yellow.

Si-OAT (Silicated HOAT) – Silicates and organic acids – Purple. P-HOAT (Phosphated HOAT) – Phosphates and organic acids – Blue or pink.

If you are wondering which of these types of antifreeze is correct for your car, always check your owner’s manual – every vehicle differs, and using the wrong type of antifreeze will likely cause expensive or irreversible damage to your engine. Antifreeze is the hidden hero of our car’s engines. If you don’t know how antifreeze works ,it’s pretty simple.

It’s why the liquid in your radiator doesn’t freeze when everything else seems to be! It prevents corrosion and helps to stop a vehicle from overheating, keeping your engine healthy and happy. There are two main types of antifreeze: concentrated and ready mixed. It stops the water from freezing under normal cold weather conditions. As well as lowering the freezing point, it also raises the boiling point of engine coolant.

Along with a pressurised system, this helps to reduce the risk of overheating.

The choice of antifreeze and its ready-to-use , water-mixed form , engine coolant , differs between vehicles. If you’re looking to top-up or flush and re-fill your cooling system , this guide will help you find the correct coolants for your car. What’s the correct antifreeze for my car? Multiple types of antifreeze are available. Traditionally, the colours are: Green : This is the colour of vehicle antifreeze composed of ethylene glycol.

It contains additives that protect metals,. Orange: Orange (sometimes yellow) is the colour of antifreeze composed of propylene glycol. It has similar properties to. Typically, older cars. AS ITS NAME SUGGESTS, antifreeze is designed to keep the water in your car’s engine from freezing.

But it’s also designe rather confusingly, to keep your engine cool by reducing the chances of the water in the engine from overheating – just about every single engine on-sale today (petrol and diesel) is water-cooled. An antifreeze is an additive which lowers the freezing point of a water-based liquid. Common antifreezes increase the boiling point of the liqui allowing higher coolant temperature. Because water has good properties as a coolant, water plus antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. Don’t let your classic car become damaged because you have no anti-freeze in the coolant system.

The range of Millers Alpine anti-freeze we have on sale will ensure your classic cars internals do not become iced at the coldest time of the year. Used to be, every make and model of car required a specific kind of coolant (sometimes called antifreeze ). These days, however, there are universal coolants on the market that provide a broad spectrum of protection. Decades ago, the color of specific coolants related directed to the chemicals they used to prevent corrosion.

Difference between engine coolant and antifreeze Coolant is the liquid that circulates around the engine and antifreeze is usually a concentrate of glycol that requires dilution before becoming the coolant. But what happens to a car when there’s no coolant in the system? Most modern engines have aluminum cylinder heads, which require the protective anticorrosive properties of antifreeze. Some coolant recovery systems are pressurized and have a radiator pressure cap instead of a normal cap. OEM certifie so you know it works well and lasts long.

When mixed with water it is called coolant, due to it also raising the boiling point of the liquid in the cooling system. Pure antifreeze must always be mixed with water before use, allowing it to regulate engine temperature in extreme hot and cold environments. There are advantages to using only one type of coolant, both for newer and for classic cars. Classic car owners traditionally use inorganic acid coolants, the ones that are ethylene-glycol-based and bright green in color. As the temperature outside changes from hot to cold coolant is pumped throughout the engine block to maintain an even operating temperature.

Maintaining proper fluid levels also helps to prevent corrosion. Besides that, Maxlife coolant will help lubricate the internal seals and parts which the liquid comes in contact with. Another option is just to simply ask the mechanic to test your coolant efficiency before winter settles in. Penrite Classic Car Coolant is a Type B, colourless, hybrid-organic, non-glycol base corrosion inhibitor concentrate designed specifically for use in veteran, Edwardian, vintage and classic car cooling systems. It protects against corrosion, cavitation, scaling and oxidisation.

A 50:mix of antifreeze and water is the most common – this raises the boiling point of water to between 240°C and 270°C, and lowers the freezing point to around -37°C. It’s important to always use coolant in your car, not pure antifreeze, as antifreeze has a much higher freezing point of around -20°C. Basically, coolant or antifreeze, which mixes with water in an engine’s cooling system is designed to both lower the freezing point and raise the boiling point of the system. Winter is amongst some of the hardest times a car will face. Car Anti-Freeze and Coolant Tester Densitometer Tester Performance Tool M4P£36.

A coolant may lose its integrity quickly in an older model car with an already rusted radiator whereas, in a new car , the coolant may last for as long as it’s manufacturers claim. Also, if you happen to use your car for great distances, it is advised that you change the coolant as per the advice of the coolant manufacturers and your car ’s owner manual. At first, these seem to be about the well-known tendency of antifreeze to find the tiniest hole and cause leaks.

However, in some cases it has led to catastrophic engine problems.
