The pre-diluted stuff is more convenient of course, but you end up paying a lot more for less coolant. Years ago coolant was always sold as pure coolant, and you'd have to dilute the fluid yourself with water. One thing to keep in mind with nearly every modern jug of coolant you’ll come across: They’re all pre-diluted. All GM cars use something called Dex-Cool from the factory. Plenty of others like BMW and Volkswagen do the same thing. Many times, the coolant is actually branded for the car you’re going to put it in.įor example, Honda sells its Type 2 Antifreeze/Coolant in all its dealers. Its specially-formulated inhibitor package accommodates all. They’ll sell the coolant for your specific make and model, and it’s guaranteed to be the correct one. Evans Waterless High-Performance Coolant maintains a boiling point of 375 degrees Fahrenheit and contains no silicates or phosphates. The easiest way to make sure you’re getting the right coolant for the job is to go to your car’s dealership. Finally, HOAT is a derivation of OAT that requires the same time change interval unless otherwise specified. General Motors vehicles use this formula and normally require a change after five years or 50,000 miles. It needs to be changed every two years or 24,000 miles, making it far inferior to newer formulas. If you have any questions about any of the ingredients in coolant, you know where to find us.Typically, older cars use IAT. This post does a good job explaining why. It’s important to note here that you should never mix different coolants together. Some of the most common coolant colors include:
Each color represents a certain type of coolant. Coolant always starts off colorless, but then the manufacturer adds dye to it. Have you noticed that coolant comes in many different colors? There’s a reason for that. Honda engines are very, very good and it costs a little more to get the special fluids to maintain. The primary functions of cutting fluid are chip evacuation, cooling, and lubrication between the tool and.
#Coolant fluid how to#
Silicates (which protects aluminum from rust) How to apply coolant and cutting fluid in turning.Phosphates (which protects iron from rust).The manufacturer’s own blend of chemicals that protect engine components (like the water pump) from rust and corrosion:.More than 90% ethylene glycol (in most cases, depending on the manufacturer).The composition of antifreeze is as follows: In other words, antifreeze makes it possible for the coolant to not freeze at freezing temperatures, and not dissipate into steam at hot temperatures. Coolant contains antifreeze because it lowers the coolant’s freezing point and increases its boiling point. AntifreezeĪntifreeze is another name for ethylene glycol. Wouldn’t overheat and create steam pressure within the motorĮventually, they found a way to bring water to the next level, and they didn’t expect it to be so simple.Wouldn’t freeze in freezing temperatures.Some vehicles recovery tanks are pressurized when. Wouldn’t rust out the components within the engine If you have to add more than a quart of liquid to the cooling system, use a glycol/water antifreeze mixture.So people set out to find a foolproof solution that: Finally, water would overheat in hot temperatures and create steam pressure within the motor. We all know that ice can’t move through the engine. Another big issue with water is the fact that it freezes in cold weather. But it was still not good enough because it still caused rust. People back in the 1930s tried to reduce the issue by using distilled water. Water is quite corrosive, which is bad news for the components within the engine. Just because water is the best way to cool the engine doesn’t mean that it’s good for the engine. While you perform this service, inspect the hoses and. You might be wondering, “If water is the best way to cool the engine, then why does coolant even exist? Flushing the coolant and replacing it with fresh fluid every two years or 30,000 miles is a good rule. It’s no wonder, because water is the best way to cool the engine. Here’s a fun fact: in the 1930s, some car owners cooled their engines only with water. Let’s talk about each ingredient in more detail. Let’s discuss the three main ingredients in coolant. Yet, they all use the same main ingredients. If you’re here, you may be wondering what the heck goes into coolant to make it so useful within the engine.Įvery coolant brand has its own proprietary blend of liquids and chemicals. It all sounds pretty neat, doesn’t it? Coolant is magic. It smells good to them, but it will kill them.” It also doesn’t freeze at subzero temperatures. Next, it dissipates the heat through the radiator. It absorbs the scorching heat from the engine to keep it at a manageable temperature. Have you ever had to explain coolant to someone? If so, you may have said something like, “Coolant is a sweet-smelling special blend of liquid that runs through the engine.
