Your car's cooling system is mostly unseen, unheard and mostly forgotton. You need to know that most busy dealerships do not always change your coolant when it is specified. To the mechanical layperson a full coolant tank requires no further thought. However that is not so, it is more than coloured water, the coolant is the life of your engine. Engine coolant does so many essential functions it really is the life blood of your engine. Without chemical analysis nobody can tell if the coolant has been changed or you have simply been charged for it. Modern car servicing is a high trust business and engine coolant does have a limited effective service life.

What is Engine Coolant and What Does It Do?
An engine coolant is a heat transfer fluid designed to remove excess heat from an internal combustion engine. It also serves to prevent freezing and most importantly protection from corrosion. An operating engine typically converts only one third of the energy derived through the combustion of fuel into work that moves the vehicle. The other two thirds is converted into heat, of which one third goes out with the exhaust. This leaves the remaining third in the engine block, necessitating the need for a coolant to adsorb this heat, transport it to the radiator and dissipate it into to the environment. Through the removal of this heat by the coolant fluid, the engine is able to operate in an efficient manner. Therefore engine coolant is a generic term used to describe fluids that remove heat from an engine, in effect cooling the engine.
Corrosion is the modern engine killer and Coolant is the vaccine to prevent this fatal infection
The vulnerable parts are the engine block, the alloy type in particular. If corrosion sets in at the edge of the water jacket then the head gasket is compromised and that is the cancer that kills your engine. Many sundry parts are also victim but the replacement cost of these ancillaries is tolerable compared to losing the engine.
Not all fluids are efficient heat transfer materials when employed in the extreme setting as found in a combustion engine.
Selection of the proper fluid is influenced by the environment in which the engine is used and the interaction of the fluid with the materials that comprise the engine. Some environments such as those found in northern latitudes may expose an engine to periods of extreme cold, requiring the fluid remain liquid in order to function properly. In effect, the heat transfer fluid must be impervious to freezing or expressed in other terms, it must possess anti-freezing characteristics. It is for this reason that engine coolant is sometimes referred to as antifreeze. Antifreeze is a more specific term used to describe products that provide protection against freezing. Many people use the terms coolant and antifreeze interchangeably. However not all engine coolants need to provide freeze protection. This is especially true when equipment is used in tropical climates. In this type of climate you will always need an engine coolant but you may not need the coolant to have freeze protection.
Consequently water based coolants are often used in these regions. So in effect, the type of coolant fluid used depends on both the application and the geography/climate in which it is used. For the purpose of consistency, we will use the term coolant when describing an engine heat transfer fluid.
To go a little further in what makes it tick.
Conversely, during engine operation the fluid must possess the ability to remain a fluid as it is heated during operation. It must resist the tendency to boil and form vapours as this reduces its ability to transfer heat. An efficient heat transfer fluid for use in combustion engines may require a low freeze point as well as an elevated boil point ensuring its capacity to perform in all situations encountered in the environment. Such characteristics are exhibited when glycols are combined with water and for this reason form the basis for all engine coolants.
The two main glycols that are used as engine coolants are: ethylene glycol and propylene glycol.
Both can be used in automotive or heavy-duty engine coolants or glycol-based heat transfer fluids, although it is generally accepted that ethylene glycol based fluids when used as directed offer the greatest cost-effective performance advantage. Propylene glycol based engine coolants or low temperature heat transfer fluids tend to be used in locations where a low toxicity product is required and due to the toxicity of ethylene glycol it cannot be used.
Highways reccommend that this preventative cooling system maintenance check be performed no less than once every two years. Consult your vehicle owners manual for specific vehicle guidelines. This inspection is designed to identify areas that need attention, and consists of:
- A chemical analysis of coolant
- An engine cooling fan and sensor test for proper operation.
- An internal leak test to check for combustion gas leakage into the cooling system.
- A pressure test to identify any external leaks to the cooling system parts; including the radiator, water pump, engine coolant passages, radiator and heater hoses and heater core.
- A thermostat check for proper opening and closing
- A radiator cap pressure test to check for the recommended system pressure level
- A visual inspection of all cooling system components, including belts and hoses
A typical car or 4x4 engine cooling system diesel or petrol type.
Cooling system things you can watch for:
- Radiator hose
- Replace bulging, rotten, or brittle hoses and tighten hose clamps. If a hose looks bad or feels too soft or too hard, it should be replaced
- Belts with spring-loaded tensioners do not require manual adjustments
- Inspect belts monthly. Replace belts that are worn, frayed or glazed. Adjust belts when more than 1/2 inch can be depressed between the pulleys
- CAUTION: Do not remove the radiator pressure cap when the engine is HOT
- Water quality plays an important role in protecting the cooling system. A high mineral content may cause scaling or corrosion. Deionized or distilled water should be used in 50/50 solution
- Check antifreeze/coolant level monthly. Only use a 50/50 solution of anti-freeze/coolant and water
