Refrigerant Liquids
The first refrigerant used in water coolers was of course water. But very soon they discovered the limitations and weaknesses it had:
- Water becomes ice at 0 ° C, temperatures that are very common in several countries of the world. When water becomes ice, it swells and causes damage to the machine, even cracking the radiator or the machine head.
- Water is corrosive and over time erodes the internal parts of the machine. All corrosion products (small rust flakes) slowly ended in the radiator, resulting in a barrier and overheating of the engine. In extreme cases, the rust scoured metal parts of the refrigerant circuit, resulting in coolant leakage and engine overheating.
- Water is a good conductor of electricity and can not protect the internal parts of the machine from electrolysis. Electrolysis is generated by static electricity due to the movement of water through the thin cooling coils of the machine. The effect of electrolysis is to channel static electricity at one point and punch that point.
Evolution of Refrigerant Liquids
The first development in refrigerants was the addition of anticoagulants so as not to freeze the liquid to zero degrees, but to withstand several degrees at zero. Later, several chemical components were tested to improve their performance and eradicate erosion. A major development was the creation of MEG-Mono Ethylene-Glycole-based refrigerants and MEP-MonoEthylene Propylene, with which they removed older, ineffective formulas and their environmentally harmful components.
Today, machine requirements have increased since:
- As the machines diminish in volume, the pipes that circulate the refrigerant are also diminishing.
- Modern machines are more efficient and produce much more heat to be fed into the environment via the radiator.
- Radiators tend to be smaller in modern vehicles, as are grilles that are smaller for more aerodynamic shape. Machines are additionally charged with the air conditioning radiators.
- Aluminum use in machines is now universal.
Contemporary Cooling Fluids
Higher fluid velocity through the refrigeration circuit increases friction and electrolysis problem. The last type of coolant is the so-called 'organic' type which is much more aluminum-friendly and reduces fluid friction. In addition, to avoid electrolysis, most vehicle manufacturers recommend a 50% solution (half a liquid and a half of water), which has prompted several refrigerant manufacturers to limit the disposal of the concentrated liquid and to promote the disposal of the ready solution after it has several advantages:
- Most vehicle manufacturers are now asking for a 50% solution, when the need for dissolving the condensed refrigerant at the ratio demanded by each manufacturer ceases.
- The water used in the ready solutions passes through electric filters that extract the anions (the salts of water), thus leaving the cooling circuit cleaner.
- In the ratio of 1: 1, the solution has a significantly increased absorption and rejection capacity of the heat in relation to water or even traditional cooling liquids (green or blue).
Finally, refrigerants should be replaced at regular intervals, every 3 years for non-organic type and every 5 years for organic coolants.
CEPSA now offers an organic type of coolant, 50% solution. Because it meets the latest VW specifications, the G-12 Plus is produced in a characteristic violet color that is part of the specification for these refrigerants. It is suitable for all vehicles and machines, especially those with aluminum engines. Although coolants of different types and / or manufacturers do not have to be mixed, the G-12 Plus is perfectly compatible with any type of organic coolant of any color.
It is advisable to clean the radiator and the circuit inside the machine by using a radiator flush when changing the radiator fluid.
Refrigerant Liquid Replacement
PRO-TEC produces the Radiator Flush which is very efficient and very easy to use. Essentially, remove the old liquid from the radiator and fill with water, adding a Radiator Flush. It is good to work the machine with the vehicle moving for 15-20 minutes and then drain the soiled water and fill it with fresh water. Let the engine work for about 5 minutes, while looking at possible water leaks. Then drain the water and fill the radiator and circuit with CEPSA Organic Coolant 50%.
