Only Prestone Asian is rated for 15 years/350k miles, not Peak. Prestone is excellent and if you don't care about color, it's the same as their universal formula and you could just get that and save even more.
And be sure to get it at Walmart, don't buy from an auto parts store and spend more...
There is nothing wrong with 2EHA, it is the holy grail of corrosion inhibitors. I have been using cheap house-brand Dexclones like Supertech since 2007 in all kinds of Asian vehicles with no issues whatsoever. I've had it in my current daily driver, a 2006 Honda Civic, since 2008 and again...
Its a Dexclone and will be fine. Next time, save more money by just buying a house-brand universal extended life coolant like Supertech or when it's on sale, Napa 1EXT.
Someone likely did a drain and fill with a Dexclone. The OEM coolant is blue. Blue Honda coolant and Yellow Dexclone make green. But it's fine, this illustrates what I've been saying for years now, Dexclone coolants are great. There is no reason to spend more, unless you're still under...
The E-core is done, this one with louvers is the latest version. I went looking for the E-core version of the 7317 Extra Guard and every Fram model has converted to louvers. I really wonder if we'll see the nylon cage again or if it's gone for good. I checked 3 different Walmarts and couldn't...
Subaru formerly used CCI for their OEM coolant. Their current supplier is Prestone and it is the same as Asian blue formula (which is Dexclone dyed blue). Just go on Amazon and search for "Subaru OEM coolant" and you'll see the newest stuff. Look at the image of the back of the bottle, you'll...
Leave it be and sleep easy. Save both your money and the environment. Honestly, you could just run that coolant for the life of the truck or until a cooling system component requires replacement and still be all good.
Late last year, I discovered the PH7317 had become an E-core with a non-silicone (black) ADBV. I liked the change and welcomed the nylon cage core. Before long, the silicone ADBV came back and I noticed that all the Fram filters (Extra Guard, Tough Guard, Ultra and Endurance) had adopted the...
The yellow green coolant that is already in there is likely a Dexclone like Prestone, Peak Long Life, Supertech or any other house brand extended life universal coolant. It's perfectly fine, there really is no need to convert to the Asian formulas. You mentioned you bought this truck 5 years...
2EHA won't cause any harm at all. 2EHA does not eat old gaskets, rather it keeps them soft, supple and conditioned. Your gaskets will last longer with 2EHA implementation.
No issues whatsoever. I have used Dexclone coolants in various Asian cars since 2007 with no problems at all. Drain/refill, full flush and top off of whatever is in there...all works fine. My current daily driver is a 2006 Civic that has been on it since 2008. It's had Prestone, Supertech...
