AnswersDrivePropylene glycol can be mixed with ethylene glycol without causing harm to the cooling system, but it does slightly weaken the heat transfer.
In this manner, what is Dexcool?
Watch for signs of oil or rust. The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
What is Dex antifreeze?
Prestone Dex-Cool Extended Life Antifreeze/Coolant, 1gal: For use in all vehicles that require Dex-Cool coolant and all other cars and light duty trucks with aluminum radiators. Patented Prestone Antifreeze/Coolant formula. Helps maintain your car and reduce wear during use.

What is the color of propylene glycol?
Inorganic Acid Technology (IAT) is the chemical composition for the traditional antifreezes that are green in color. An IAT can be used with either ethylene glycol (EG) or propylene glycol (PG). The normal IAT service life is two years or 30,000 miles (50,000 km).

What do you get when you mix green and orange?
You can't make them by mixing any other colors. Orange, green and purple are the secondary colors. A secondary color is made by mixing two primary colors. For instance, if you mix red and yellow, you get orange.

Can you add water to g12 coolant?
If you're looking to change your coolant, make sure you flush your radiator system a couple of times and then add Prestone (or any other regular coolant). A sidenote: if you're ever using water with any coolant of yours (yes, diluting coolants is no problem) and if you're using G12, please use distilled water only.

Can you mix ethylene glycol and propylene glycol?
Propylene glycol can be mixed with ethylene glycol without causing harm to the cooling system, but it does slightly weaken the heat transfer.
5
What is the difference between green and orange antifreeze?
Although both the green and orange antifreeze are ethylene glycol-based, the difference between them is that they contain different corrosion inhibitor ingredients or additives. While orange antifreezecontains organic acids, green antifreeze has additives, such as silicates, borates and phosphates.

Why glycol is used in chiller?
The use of an industrial inhibited glycol and water mixture is recommended in most water chiller systems. Ethylene and Propylene are the two standard types of inhibited glycols commonly used. The main job of glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating temperature.

What is the flash point of ethylene glycol?
Physical Properties
| Physical Properties (1) | Monoethylene Glycol MEG | Diethylene Glycol DEG |
|---|---|---|
| Surface Tension, dynes/cm @ 25°C (77°F) | 48 | 44.8 |
| Refractive Index @ 20°C (68°F) | 1.430 | 1.447 |
| Specific Heat @ 25°C (77°F) Btu/lb/°F | 0.58 | 0.55 |
| Flash Point, °C (°F) | 116 (241) (2) | 154 (310) (2) |

Can you mix red and green antifreeze?
Realize that green antifreeze is the old style antifreeze. So it's a better antifreeze to use. Now, if you mix them--they are not supposed to be mixed--but if you mix them it's not like mixing an acid and a base and you are not going to have and explosion or anything like that.
9
Can you add water to your engine coolant?
Although water can be added to the radiator for this purpose, it's preferable to add a mixture of coolant and water because plain water can boil before the proper coolant will boil, causing your engine to overheat [source: pontiac]. A car radiator cannot work if there isn't enough coolant inside the system.
10
What will happen if you mix green and orange antifreeze?
This is one of those questions usually asked after the fact, and usually engine damage has already occurred. The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow and consequently the engine overheats.
11
What is the freezing point of ethylene glycol water?
Antifreeze. Pure ethylene glycol freezes at about −12 °C (10.4 °F) but, when mixed with water, the mixture freezes at a lower temperature. For example, a mixture of 60% ethylene glycol and 40% water freezes at −45 °C (−49 °F).
12
How much does it cost to have your radiator flushed?
The cost of a coolant flush typically runs between $100 and $150, according to highly rated mechanics. Kauffeld says this can include four gallons of coolant, a conditioner and a cleaner. CostHelper.com estimates the cost between $54 and $144 for a radiator flush at a standard shop, with an average price of $99.
13
Why is glycol used in heating systems?
Glycol is added to water systems because it is effective in reducing the freezing point and minimizing the risk that pipes will freeze and be damaged. Yes, glycol does affect the efficiency of heating systems because it does not transfer heat as well as plain water.
14
What color is Prestone antifreeze coolant?
Newer coolants such as Prestone, based solely on the OAT chemical make-up, now offer a 10-year or 150,000-mile change interval thanks to their superior corrosion protection. Prestone is yellow, but many other coolant manufacturers use different colours.
15
Can you mix water and antifreeze?
As @Larry has stated straight water or antifreeze are not ideal coolants when used alone. When mixed in a 50/50 ratio the boil/freeze point is ideal for all but the most extreme climates. Although it is more expensive, premixed coolant is available which will allow you to refill the system with the proper 50/50 mix.

What is a glycol heating system?
Thermal Fluid Systems. Thermal fluid heating is a type of indirect heating in which a liquid phase heat transfer medium is heated and circulated to one or more heat energy users within a closed loop system. Thermal oil, glycol, and water are common heat transfer mediums for these systems.
