Second, you must find out what the base of the coolant is. First, you have to find what type of coolant you need. When it comes to selecting a coolant, there are two things which you should take into account. What are the different types of coolant? What is a coolant inhibitor? While some coolants are compatible with others, changing the chemical balance in the cooling system can affect coolant performance, so mixing different types of coolant is not recommended. Coolant should be changed at recommended intervals because some of the additives will age and deteriorate over time, reducing the effectiveness of the coolant. What types of additives are used in coolants?Ī fully formulated coolant is comprised of a careful balance of ethylene or propylene glycol with rust inhibitors, corrosion inhibitors, scale inhibitors, pH buffers for the acid to alkaline balance, anti-foaming agents, and reserve alkalinity additives. Manufacturers can recommend other specific mixture ratios, but below 33.5% Glycol the coolant will give inadequate freeze protection, and above 65% Glycol the mixture has inadequate heat absorption. This will lower the freezing point of the fluid to minus 39☌ and raise the boiling point to 108☌. A common Glycol to water ratio used is 50:50. Glycol does not absorb heat as effectively as water, but when added to water it has the ability to lower the fluid’s freezing point as well as raise its boiling point. Propylene Glycol, which is non-toxic, is sometimes used in the mixture, as well as, or even instead of, the more toxic Ethylene Glycol. What is coolant made of? It's just water right?Ĭoolant is normally a concentrate fluid, usually made of Ethylene Glycol together with some protective additives that is mixed with demineralised water to produce coolant.

#SUBARU SUPER COOLANT COLOR CRACK#

When an engine stands idle in cold weather, water in the cooling system will expand as it freezes, and this can have sufficient force to crack the engine block or radiator. The amount of heat generated by an engine is the equivalent of that required to heat a large house in winter in very cold climates! As engines and vehicles become smaller and more powerful they generate even more heat in a confined space, and aerodynamically efficient body designs tend to direct air away from, rather than into, the engine bay.

Coolant related products:Ĭoolant is commonly a liquid substance that is used in a closed system to reduce and regulate the temperature of an engine. When water starts to boil, it'll build up pressure from the gas expansion in the system causing it to overheat the system and blow vital gaskets.

But before that, you will find that water boils at 100c and freezes at 0c, this works outside the optimal range for engine requirements as some engines will heat up over 100c especially on hot days. If you choose to use only tap water in your cooling system, this can cause radiator, head gasket and thermostat corrision damage over time.

#SUBARU SUPER COOLANT COLOR MANUAL#

If you're still not sure, check the owners/service manual for coolant specifications. Most coolant brands will keep their coolants the same colour to prevent any confusion.

The most common method to find out is to simply check the coolant and find out what colour it is when the vehicle is cold. If you use the wrong coolant then over time you’ll begin to notice a drop in your car's performance, and can find a significant amount of damage. When it comes to the coolant you must make sure that you’re using the right one. Once this is completed you will be suggested the right products to suit/fit your vehicle while searching our site. All you need to do is punch in your rego and state or search by make, model and year. You can find the right coolant and parts for your vehicle by using the My Garage tab at the top of this web page.
