Can you mix blue and green coolant Hyundai

Indeed, coolant is essential for your car; and its primary purpose is to transfer heat and prevent your car engine from getting damaged by severe freezing or heat.

So, can you mix blue and green coolant? Yes, you can mix blue and green coolant, but make sure that they are of the same type when you make them. 

Mixing them can protect the metals and non-metallic parts in your, including the cooling circuit. For example, check out below what will happen if you mix blue and green coolant.

Can You Mix Blue And Green Antifreeze?

Yes, you can mix blue and green antifreeze as long as they are in the same type. For example, you can mix blue with your old green antifreeze without getting a problem. 

Mixing blue and green antifreeze creates a liquid coolant that is perfect for cooling your engine while you’re driving your car. 

But if you try mixing a significant amount of one type with another, you are just weakening your car corrosion inhibitors. These will lead to future problems that will cause an accident if you don’t prevent it. 

An antifreeze color is made for convention when choosing your car so that it is easy for you to choose the best antifreeze for your car. 

It is because mixing the wrong antifreeze could end up your antifreeze turning to gel rather than liquid. When your antifreeze turns to gel, it will block the passage of your coolant system, and it will not cool your engine enough. 

It would be best never to mix any coolant based on your color perspective because there are instances it won’t match your car engine. If you have no idea what color of coolant your car needs, ask for expert advice. 

Is There A Difference Between Blue And Green Coolant?

Yes, there is a difference between blue and green coolants. Green coolant is the color of a healthy engine coolant, the same as an orange. 

The rusty colors indicate that the coolant in your car has broken down. It can no longer control the rust and scale buildup in your coolant system. 

While, if your coolant gets milky, it indicates the presence of unwanted oil in your car system. 

Moreover, checking your coolant is easy to forget, but you shouldn’t because engine coolant is the same as necessary as your car oil. As an owner, you should be responsible for your car; it is also for your safety and the people you are with when you’re using your car. 

What Will Happen If You Mix Blue And Green Coolant?

Mixing two colors with the same type creates good results for your car. It will protect your car’s coolant system properly and effectively. 

You must always check your car’s coolant if it’s still in good condition because coolants could rise to a boiling point during summer and lower during winter. 

To maintain your car coolant system function, first, you should check your coolant, then if you notice something that is not right, call a technician right away.

Never do the job if you don’t know about it because you might put something in your car that isn’t intended for its system.

Summary

In summary, there’s no problem in mixing colors of coolants for your car. However, make sure that the color of the coolant you will mix is with the same brand and type. 

Because mixing it with another color with different brands and types might block your cooling system and cause misfire and engine failure. 

Doing this makes sure that your car cooling system is in good health and will protect your car engine adequately during any weather.

He's correct yes you can mix the new blue with your old green. We do it all the time at Honda. On my own personal car I drain the radiator and the block than fill my whole system with the blue coolant. That's just me tho.

this is wrong. You can mix IOAT (red,gm-yellow,ford-blue,honda-etc) and OAT (green) coolant. Once you do that though you have to start following the service schedule for the oat (green) coolant. which is about every 2 years. The difference in the coolants is the additives they have in them. The extended mile stuff uses InOrganic Additives which last longer, while the green stuff has organic additives which doesnt last as long.

mixing gm dexcool(orange) with green is bad. a chemical reaction between the two turns it to sludge

thats pretty funny considering I have been using "lesser quality" coolants in my hondas since about '95. I have never had an issue with excessive corrosion, plugged radiators, or leaky water pump seals. That article just looks like marketing propeganda to me, we get **** like that all the time from the different manufacturers we deal with. If the proper maintance schedule is followed the part will fail long before any issue arise from a non-honda fluid. Im not argueing that they havent designed a superior fluid specifically for their parts, just the fact that it doesnt really matter as long as the maintance schedule is followed. AND FOR THE LAST TIME MIXING DEX-COOL AND GREEN WILL NOT TURN TO SLUDGE. Where did you people get that from??? Quit speading myths, it makes my job a headache. I will bet you the cost of 2 gals of anti freeze. Go try it yourself, video tape it, and if it turns to sludge I will pay-pal you the money. I warn you though you'll just be wasting 20$, hell buy a paint mixer and heat it with a torch and it still will not turn to sludge.

Re: Can I mix my green oem coolant with the new blue Type 2 coolant.


why did they have to add coolant to a vehicle with 9000 miles? exactly, something caused the coolant to be low, customer overheated it, then added coolant to the already damaged engine. your dealership was looking for a way to avoid paying for an engine. You are wrong. dexcool will not cause any chemical reaction that will cause a toyota to overheat, something else did

Re: Can I mix my green oem coolant with the new blue Type 2 coolant.


Hey guys, apologies for restarting an old thread. But I am trying to get a definitive answer to my question below:
My Accord 2006 (4Cyl) was due for an Oil change. Took it to the local shop (Car-X) and got the oil changed. The car previously had the Blue coolant (guessing Type 2). Since it was low, the shop topped it off with Green coolant from Valvoline.

Will this harm my engine/coolant system? If so, should I get my radiator flushed and replace with all new Honda Type 2? Approximately how much does that cost?

Thank you!

Honda Green is compatible with Honda blue,though it will render the life of the blue coolant shorter. Valvoline Green however is likely formulated to be "universal" and may or may not be compatible with your vehicles current coolant.

Ignore everything srmofo has said. It is pure ignorance.....

Thank you so much DCFIVER! I appreciate the reply.

Considering that the Valvoline Green may not be compatible with the Honda Blue, I am planning to get a Coolant flush with the Honda Type 2 Coolant. I guess that should resolve things. So I'm out a $100 then

I HAVE ALWAYS READ ON EVERY NEW RADIATOR I HAVE SEEN A LITTLE SIGN STATING "AVOID MIXING OF COOLANT" OR SOMETHING LIKE THAT MY ADVICE DRAIN AND REFILL ITS NOT THAT HARD JUST BE SURE TO LEAVE VALVE OPEN THAT IS USED TO LET AIR ESCAPE DON'T LET ANY AIR REMAIN IN LINES

Re: Can I mix my green oem coolant with the new blue Type 2 coolant.


You should only add the same coolant you have in the car. Red/orange definitely don't use because those are specifically for some European cars. Now if you wanted to change it to blue then empty it, cycle some plain water through it to wash it out and add blue. Mixing can occasionally cause the coolant to clog up.

Is it OK to mix green and blue coolant?

The answer to that is Yes. You can mix Peak with Zerek or Prestone – but only as long as the coolant is the same chemical type. The ratio doesn't matter as much, but the type & application should match. The easiest way to remember is that you should try and match type – IAG with IAG, OAG with OAG and HOAT with HOAT.

What coolant does Hyundai recommend?

Genuine Hyundai Fluid 00232-19010 Long Life Coolant - 1 Gallon.

What Colour is Hyundai coolant?

OEM Ready-to-Use Extended Life Antifreeze/Coolant Yellow is specifically formulated for Hyundai and Kia vehicles and is suitable for hybrid & electric models.

Can you mix 2 different colors of coolant?

Can You Mix Orange and Green Antifreeze? It's never a good idea to mix two different colors or types of antifreeze. Mixing two formulas won't cause any dangerous reactions or explosions, but it could turn your coolant into a sludgy chemical mixture that won't be able to flow properly through your cooling system.
