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.

well, i dont know what chem. reactions happen when mixing dexcool and the reg. ****, but i can say i have personally seen a toyota with 9,000mi. on it completely ruin a longblock (head and block warped due to overheating) from being filled with dexcool. no sludege, just f*ked...take it or leave it.

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 okay 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.

Is it OK to mix coolant colors?

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.

Can you mix two coolants?

The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.
