Which antifreeze

What does antifreeze stand for? 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 antifreeze you nee always check your owner’s manual – every vehicle differs, and using the wrong type can rapidly damage your engine. There are two main types of antifreeze: concentrated and ready mixed.

While concentrated needs to be diluted before it can be use ready mixed is, as the name suggests, ready to use straight away - ideal for topping up while on the road!

Besides that, Maxlife coolant will help lubricate the internal seals and parts which the liquid comes in contact with. 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. The biggest thing to look out for is using the organic acid technology (OAT) in older vehicles with brass or copper radiators. 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. Antifreeze is the hidden hero of our car’s engines. If you don’t know how antifreeze works ,it’s pretty simple.

It’s ready to use – Simply flush and fill the whole system or top-up and go – the choice is yours.

Zero deposits – If you use water or low-quality coolant in your car, deposits like limescale can build up and cause problems. Ethylene glycol: the most common car antifreeze, used over glycerol due to its lower freezing point even though it’s toxic to humans. Organic Acid Technology. Classic car owners traditionally use inorganic acid coolants, the ones that are ethylene-glycol-based and bright green in color. It’s also known as engine coolant.

Although water-base antifreeze also contains liquid alcohols like. Both ethylene glycol (EG) and propylene glycol (PG) are used as the antifreeze base. From here the additional additives and inhibitors are added.

Each glycol has supporters, although the best choice depends on the intended use. Keep your wheels on the road when the weather turns chilly with red antifreeze , which offers protection for your engine in even the coldest conditions. Also helping guard against rust and corrosion, red antifreeze is suitable for a wide variety of makes and models. An alternative to tradition green antifreeze is a product currently used by many vehicle manufacturers.

Orange or Red antifreeze known as long life or extended life antifreeze increases the useful. So, what does antifreeze do? Therefore, modern antifreeze coolant contains chemicals which protect the internals of and engine from corrosion - including the water pump, which is often located in awkward places that make. Methanol: a highly combustible, toxic liqui methanol is used in vehicle windscreen washer fluid and de-icers.

Glycerol (also called glycerine): non-toxic and able to withstand higher temperatures than its counterparts, glycerol. There are advantages to using only one type of coolant, both for newer and for classic cars.

Inorganic acid technology is perhaps the most common and is the chemical basis for traditional green antifreeze. It is usually fortified with silicate or phosphate and needs to be replaced every three years or 30miles. There is also a hybrid option that combines organic and inorganic acid technology.

Evans holds the record as the best antifreeze brand since it’s the only manufacturer of waterless antifreeze. Zerex always has the best antifreeze. Star Brite is a leading.

Some car brands can only be used with antifreeze brands that contain ethylene glycol. You don’t want to feed your radiator the wrong coolant. Modern antifreeze , he says, is 96-percent ethylene glycol, which provides the freeze protection, and four-percent additives. Ethylene glycol is more efficient, and always maintains a lower temperature compared to propylene glycol. It is usually made by mixing distilled water with some kind of alcohol, such as methanol, glycerol or ethylene glycol.

When containing the latter it can be highly poisonous when ingested in even the smallest amounts. Long life antifreeze is also ethylene glycol based.
