Okay, so things are really starting to come together here, and I really do appreciate all your patience. Maybe one last thing: Which kinds of coolant should not be mixed? Is it okay to mix a HOAT with OAT, or a P-HOAT with and OAT? (Ford's yellow seems to be a P-HOAT, and I have been strongly...

This is super informative, thanks for shedding light on the G05 designation, that makes sense. Also, good to know that all the bad stuff I am reading about 2eha isn't quite true. Thanks!

Perfect! Thanks!

I suspect that 2-eha isn't as bad as some would make it seem. It certainly has gotten a lot of bad press in this forum and elsewhere, though.

P-HOAT and P-OAT are the same thing? Good to know, that simplifies things a lot, thanks!

Sorry to confuse you. First, it seems natural to me to want to know what kind of coolant is in there so that over the lifetime of the vehicle I know what I am doing, beyond this little top-off. Second, the coolant from the dealer contains 2-eha, which some on this forum are averse to using...

I appreciate the advice about not getting hung up on color, but things would be so much easier if colors were standardized, or if the containers would let you know the composition of the coolant. I see that you suggest it is P-HOAT, which makes sense, since that seems to be the composition of...

Does anyone know if this is HOAT?

Thanks, good article, I read it while researching, but it leaves me with so many questions, like: 1) What is the connection between HOAT and the label G-05? 2) What about the different uses of silicone in the HOATs? 3) Why doesn't the "Asian Red" clearly state what it is, in terms of whether it...

I'm guessing that maybe there was some air in the system after the factory fill. It was a bit below the full line on the overflow reservoir when I bought it, and dropped a bit after 5k miles. I added a about 8 fl ounces last September. Level hasn't fallen again yet, and I'm at 33,000 miles now.

There is so much I don't understand about coolant! Seems like things got pretty weird after about 1993! So I have a 2021 Kia Rio which needed a little top off of coolant. I spent WAY too much time trying to figure out if it's an OAT, HOAT, PHOAT, or maybe even a POAT (if such a thing even...

I have a 2012 Ford E-350 12 passenger van with a 5.4 gasoline powered V-8. I have been using Mobil 1 (5w-20 extended life) recently, other brands of full synthetic since I bought the van on 2013. I use Fram ultra synthetic filters. My question is this: The oil change indicator just came on. I...
