What antifreeze can be mixed?

Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage. Coolant/Antifreeze is formulated to offer a simple solution to topping up your cooling system.

Can you mix and match antifreeze?

You can mix two different colors of the same kind of coolant without any problem whatsoever. But if you mix a significant amount of one type in with the other type, you’re weakening your corrosion inhibitors (it happened to my brother, and look at the condition he’s in now).

Can you mix different Colour antifreeze?

Most of us are familiar with two kinds of antifreeze. There is green antifreeze and orange antifreeze. These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.

Does the Colour of antifreeze matter?

The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.

What happens if you put the wrong antifreeze in your vehicle?

Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages; this can result in increased corrosion to the radiator. Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket.

What color coolant is Prestone?

Prestone is yellow, but many other coolant manufacturers use different colours.

Does the type of coolant matter?

Well, you use the coolant that is specified in your owner’s manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer’s maintenance schedule.

What should I do if I mixed green and orange coolant?

If mixing happens, it is best to have the entire system flushed before driving the vehicle. This is the only way to be sure that the system is clean and not at risk. Failure to perform this flushing can, and often does, lead to engine failure and costly repairs.

What is the proper mixture of antifreeze?

However, you must mix water and antifreeze in the appropriate quantities to ensure that the coolant performs its function correctly. Generally, warm parts of the country mix antifreeze with water in the ratio of 70:30, but most manufacturers recommend mixing them 50:50. How does antifreeze work? Table of Contents [ show]

Can you mix different antifreeze?

Mixing different types of antifreezes can reduce their corrosion protection and can actually lead to corrosion problems. Engine manufacturers recommend a 10% limit on mixing coolant types. If you add more than 10%, it is recommended that you flush the system and replace the antifreeze—EET Corporation.

What are the different types of antifreeze?

There are 3 basic types of antifreeze used today, ethylene glycol based, propylene Glycol based and the newer Organic Acid Technology. The biggest thing to look out for is using the organic acid technology (OAT) in older vehicles with brass or copper radiators.

Is antifreeze and coolant fluid the same thing?

Coolant and antifreeze are, in fact, the same thing. Each term focuses on one aspect of what that fluid does, but no matter what you call it, it protects your radiator from extreme conditions.
