Engine Coolant - What Is the Best Type And Why We Don’t Use Just Water Anymore


Engine coolant enables your vehicle to operate and perform without engine trouble. The moving parts inside the engine create friction which generates heat. This is what makes an engine warm and hot. Engine coolant keeps the temperature inside the engine within parameters where the moving parts will not get so hot that they will melt or cause other damage inside the engine. 

The Basics


Engine coolant is a specially formulated liquid that contains additives that prevent it from boiling at 100C or freezing at 0C. Water, on the other hand, is not an effective engine coolant because it will evaporate at the boiling point or become ice or slush at freezing temperatures. This means that engine coolant can keep the engine of your vehicle cool at all times.

Here is how engine coolant does that. The coolant travels to the engine through pipes and hoses. As it moves, it collects heat. The warmed coolant then moves into the radiator or heat exchanger. The radiator cools the coolant and then sends it through the cycle again to collect more heat from the engine. This process repeats constantly to prevent the engine from overheating. Coolants, which are also known as radiator fluid, are effective for a couple of years but may require topping up if the level drops. Having the radiator fluid levels checked twice a year will help to monitor that there is enough coolant in the system to do its job correctly.

The Contents of Engine Coolants


There are two main ingredients in engine coolant. Ethylene glycol is what keeps the liquid from turning to slush or vaporizing in extreme temperatures. This compound has been found in coolants for many decades because it works to keep the liquid flowing through the cooling system of your vehicle without a problem.

Coolants that do not use ethylene glycol have propylene glycol instead. It does much the same as ethylene glycol but is less viscous. On the plus side, propylene glycol is less toxic. The other ingredient is water. Typically, engine coolant is a 50/50 mixture of ethylene glycol (or propylene glycol) to water.

The Different Colours of Coolants


Usually, coolant has a green tint to it. Other colors it comes in include blue, orange, red, and yellow to name a few. These are often considered to be more advanced varieties of coolants. It is best to stick with the same color of coolant your vehicle had originally in it if it is still under warranty. To be sure, the professional Redcliffe mechanic team at J&C Autos will be able to determine the best coolant for your vehicle.

What Is The Best Coolant For Your Vehicle?


Essentially, the manufacturer of your vehicle will recommend a specific type of coolant in the owner’s manual for your car. It is best to avoid purchasing coolant solely based on price. An affordable coolant that is designed to work well on most vehicles may result in becoming a costly mistake for your cooling system. The urge to save money on cheaper coolant may end up costing you more in engine repairs. To be sure, consult with the professional team of mechanics at J&C Autos.

Can You Still Use Water Instead of Coolant?


Considering water is a major ingredient in coolant you may think you can still use it alone and keep your vehicle’s engine running cool and smooth. While most automobile manufacturers have recommended coolants with a 50/50 mix of ethylene glycol (or propylene glycol) to water, there appears to be a shift developing in that stance. Some manufacturers are suggesting a 70-percent coolant/30-percent water mixture while others are leaning towards a 40-percent coolant/60-percent water split. Again, for proper direction on what is best for your vehicle, refer to your owner’s manual or discuss this concern with the pros at J&C Autos, in Redcliffe.

The moving parts inside of your vehicle’s engine create friction. This generates heat which is controlled through the use of engine coolant. The cooling system in your car depends on it and due to the extreme temperatures, a vehicle’s engine creates, water does not make a good coolant although it is an ingredient in all coolants. To be sure your vehicle is equipped with the proper coolant, book an appointment today at J&C Autos so the professional Redcliffe mechanics can inspect your coolant and replace it if required.
