Can You Mix Zerex G 05 With Green Coolant [Known A-Z]
If you mix the Zerex G 05 with green coolant without proper knowledge, it can be harmful to your car’s engine. Both Zerex G 05 and green coolant are antifreeze that has one job – to cool down the engine when it gets too hot and to keep the engine at an operating temperature.
It’s okay to mix most antifreeze or coolants with each other as they outright claim that on the label. Brands like Autozone, Peak, and Preston mention in their label that the coolant can be mixed with coolants of other colors.
But no such claim is made in the Zerex G 05 coolant. The label doesn’t mention if you can mix it with coolants of other colors. Zerex G 05 is a concentrated coolant/antifreeze that works well when mixed with water.
So, it’s safe to mix the prediluted coolants with other coolants. But the Zerex G 05 coolant isn’t prediluted. Can you mix it with green coolant?
Most green coolants are prediluted at a 50-50 ratio. So, if you dilute the Zerex G-05 coolant at a 50-50 ratio with water first, you can mix it with the green coolant. Not only can you mix it, but you’d also be certain that the ratio of coolant and water is the same in the mixture.
You can also go higher when mixing the Zerex coolant with water. But doing that will make the maths harder of how much green coolant you should mix it with. It’s safe to stick to the 50-50 ratio if you plan on mixing these coolants.
The main thing you should consider before mixing the coolants is the car. If it was made before 2000, green coolant is good for those older cars. But the Zerex G 05 is the better solution for most modern cars.
Should You Mix Zerex G05 With Green Coolant?
Many people worry about the formation of sludge or other chemicals that’ll cause corrosion if you mix them together. It’s natural to think that because the green coolants use the inorganic additive formula whereas Zerex G 05 uses the organic formula.
But that’s a misconception and there will be no corrosion in the engine unless you mix them in an unacceptable ratio. Technology has come a long way and mixing these coolants won’t harm your engine. While it’s safe to mix them, it’s not recommended that you do it as there’s no upside to it.
The long life of 150,000 miles will come down if you mix the two coolants. The special corrosion inhibitors in the Zerex G 05 won’t work as effectively when it’s mixed with a green coolant.
How Do You Mix Zerex G05 With Water?
It’s recommended that you should mix Zerex G 05 in the 50-50 ratio for normal use. But depending on the weather and driving conditions, you can go up to a 60-40 or even 70-30 ratio of Zerex G 05 and water.
Using these rations as recommended is ideal to protect the components of your engine from being frozen in the winter and boiled in the summer. This range is perfect to protect the engine from corrosion as well.
At a 50-50 ratio of G05 and water, the freezing temperature will be around -36 degrees celsius and the boiling temperature will be 126 degrees celsius.
But if you mix the G05 and water in a ratio of 70-30, the freezing temperature is nearly -67 degrees and the boiling point is 135 degrees celsius.
These numbers are there on the Zerex G05 label. So, staying in that lane of having 50-70% G 05 coolant and 30-50% water is ideal for your engine.

Does Zerex G 05 coolant come with a warranty?
Yes, the Zerex G 05 has a five-year warranty or 150,000 miles for light-duty trucks and passenger cars. But for heavy-duty applications, it has a warranty of 300000 miles or 3 years.
What are the different types of coolant available?
The three most common types of coolants available are IAT (Inorganic Additive Technology) coolants, OAT (Organic Acid Technology) coolants, and HOAT (Hybrid Organic Acid Technology) coolants.
What kind of coolant do I need?
If you own a newer car with an aluminum block in the engine, OAT or HOAT coolants are great for you. For older models, green coolant is the way to go.
Can you mix different green coolants?
It’s safe to mix green coolants of different brands. The color is only a dye and it represents that the coolants are already 50% diluted with water and they were made using the IAT formula.
What does coolant do?
The job of the coolant is to prevent the components of the engine from freezing in cold weather and from being overheated in hot weather.
Now you know the answer to the question can you mix zerex g 05 with green coolant. You’ve also learned about the right way to mix the coolant with water and whether you should mix the zerex g 05 even though it’s safe.
