LX570 Coolant - Pink mixed with Red (1 Viewer)

[Screwd up 6]

I apologize in advance if this has been posted. I tried to search but no luck and I am kind of paranoid at this point. I changed out my radiator today due to the start of the notorious leak at the top plastic. Install went well. I opted to buy my parts at Lexus yesterday as I noticed the start of the crack on Monday and we have a road trip this weekend. Everything went smoothly. I refilled the system with 1.25-1.5 gallons of pink 50/50 premixed coolant. When I was cleaning up, I took the drained coolant and poured into a clear bottle. That is when I noticed the previous coolant was more red color than the pink (pic attached). I know it is a big no no to change green for orange/red on other vehicles. My big concern is, is it ok to mix the pink and what looks like red in mine? Or does the pink darken overitme? The coolant in the truck was flushed about 15K miles ago at Lexus dealer. Anyone know if it is ok that I mixed that small amount? I can do a full flush if needed but I'd prefer not to if this is safe to run through the next week. Really just hoping I didn't screw up big time by overseeing this. Thanks in advance

I don't know for sure, but I definitely need to know more about that excursion.

Check this out, it's one of the craziest things ive ever seen. They weighed this beast in at 11K lbs.
These guys are not only funny and entertaining to watch but they do awesome well thought out mods and the whole series is just fantastic for this build.

It looks like they used the long life coolant on the last flush (red). Pink is super long life coolant, which should be the correct coolant for your vehicle. I'm not sure about the implications of mixing.

Found this on the World Wide Web. Never new the chemistry difference between the red and pink. Doesn’t look like it is a deal breaker to leave the red inside…I’d personally run the pink as it has a much longer life span and is the factory correct fluid.

"While Toyota Pink Coolant does last a lot longer than Red it is quite a bit more expensive. This is in part because it is only available as 50/50 pre-mixed formula whereas Toyota Red is not pre-diluted." I'd like to visit the place where these statements make sense.

Could it be, by any chance, 50% more expensive? LOL

It was my previous vehicle. Sold it about 2 months ago. Was a 2004 with fully built 6.0 motor by diesel performance shop. 4" BDS lift, 22x12 American Force wheels and 35" toyo MT. It was always something I wanted so when my buddy put it up for sale, I bought it impulse to scratch that itch.

That was my fear. Looks like I will be ok until I do a full flush though.

I ran across this and didn't realize until now they state it can be interchanged. With that said, I think I will run the 1.5 gallons of pink I have it it through the weekend and plan on a $$$ coolant flush next week. I just need to find the thread on here where it was discussed on how to clear out the whole coolant system including block.

The two added chemicals aren't special. Gonna give the buyer half a gallon of water, charge more than the red, and dodge a claim if someone uses the wrong coolant. BS. This is an OE making profit on parts with some underhanded methods. They're all guilty of it (GM with Dexos, Honda with 0w-16 oil, VW with odd ball fluid certifications...it goes on). Rant off.

I don't know man, personally i run
negative20W-0 with changes every 20k miles. Saves a couple dollars a year at least and keeps the epa off my back. I just cant trust all misinformation online you know? The valve springs are supposed to grenade to stimulate the economy.
Gov and corporations always have my best interest at heart. Now thats the dependability i come to expect.

There are drains on each side of the block, the passenger side is much easier to spot than the driver.

The tough part is getting the coolant out of the heater lines to the back.. I opted to flush with clean water when I did my 120k change, and had hell getting the clear water back out to make sure the new mix wasn’t diluted by it. Compressed air wouldn’t even flow due to some kind of valve or trickery back there.

Next drain/fill will be simply dumping the old pink and filling with new, confident 90%+ is getting drained. That doesn’t help your scenario much.

If you do elect to use air in the rear lines, or drain them well and allow air in, you may need to drive at higher RPMs with heat on full blast to push the air out of the back. That was the trick to returning heat to the rear core for me.

Thanks for the insight. I have been reading a lot the last few days on different ways people did the flush. Being the pink and red can mix, and mine had a flush not long ago, I think I will just drain the block an radiator, add pink. Then repeat in a few months. In theory, it will always have a small % of red still there, but I'd bet that over 90% would be pink again.

Yeah that should handle it without much trouble.
