    Are there limits to the applicability of Nitrite-free red ELC?

    2EHA is a plasticizer, but that is a good thing. It doesn't destroy plastic, but rather preserves and conditions it. Your plastic parts won't crack, craze, dry rot or deform when a 2EHA coolant is used.

    Are there limits to the applicability of Nitrite-free red ELC?

    That's great news! 2EHA is an awesome corrosion inhibitor and highly desirable. You will be well served by those coolants. 2EHA for the win!

    Does Peak OET Asian Red have 2EHA now?

    The formula change was covered in another recent thread, but I want to mention this is a step forward, not the opposite. 2EHA is an absolutely superb corrosion inhibitor and is perfectly fine in Asian vehicles. Notice the service life of the old formula was 5 year/150k? Take a look at it now...

    Overheating, what makes a Subaru a Subaru!

    That's not true at all. Take a look at used car prices nowdays, they're really high for anything decent. Not that far from buying a new car. Even if you spend $1000 on parts, it's totally worth it. Just tell yourself it's going to take about 2 weeks to do at home, watch some Youtube videos...

    Valvoline multi-vehicle

    Why are you changing the coolant on a 2 year old truck? Unless it's been somehow contaminated, leave it be. I wouldn't change from Dexcool to the universal stuff, especially if the truck is still under warranty. Leave it be.

    dexcool in rusty engine

    This is all you need to know. 2EHA is the holy grail of cooling system inhibitors. 2EHA's plasticizing attributes doesn't destroy gaskets, but rather it preserves and conditions them. It keeps the most fragile parts in a cooling system from cracking, deforming and leaking. Consider it an...

    Zerex G40 European Coolant in a GM 4.3 Vortec

    G40 is definitely a step down from Prestone AMAM or even just plain Dexcool. Those nasty silicates will coat your cooling system passages and that creates a thermal blanket that will reduce heat transfer anywhere from 7 to about 14%. The is nothing wrong with Dexcool, it's inaccurately blamed...

    Ideal Coolant - Older Toyota Engine

    Agreed, your best bet is to use a universal extended life house brand coolant like Supertech, Autozone's Shop Pro or Napa 1EXT. They're proven to protect anything and everything and I've been using them for almost 20 years now in numerous makes/models with absolutely no issues whatsoever. Yes...

    Low Coolant, Wrong Coolant, Plus a Coolant Leak - 2001 Tundra

    Timing belt is difficult and not to mention, a lot of liability for doing a friend a favor. Even if you do a perfect job, if there is something defective in one of the timing belt components that isn't visible and something fails down the road, it could destroy the engine and your friend may...

    Difficulty bleeding coolant, possibly because it's too cold outside

    On these EJ25 engines, head gasket replacement is practically routine maintenance. They all blow eventually. And once you replace them, they don't stay fixed forever, regardless of what others say. It's just a matter of time, but the same symptoms will return at some point. On a poorly done...

    Difficulty bleeding coolant, possibly because it's too cold outside

    As a long time Suby enthusiast that has done a lot of work on these EJ25 engines, I would suggest changing the thermostat to either OEM or Tama as something you could try. But honestly, this sounds like a blown head gasket. These engines are extremely easy to bleed, it takes almost no effort...

    Choosing a universal coolant (OAT ELC vs hybrids)

    Do not waste your money buying Final Charge Global, there is really no need. Simply use the cheapest house-brand universal extended life (Dexclone) coolant you can find. Walmart Supertech, Autozone's Shop Pro or Napa 1EXT when it's on sale (like right now) are all fine choices. I know it's...

    Universal coolant in 7.3L Powerstroke van

    You're trying to find a problem that doesn't exist here, nothing is wrong, continue to do as you've done with the Supertech or any other cheap universal extended life coolant. You don't need SCAs, that stuff is old, obsolete technology and it's garbage. It just coats the entire cooling system...

    Universal coolant in 7.3L Powerstroke van

    You don't need to change anything, what you're doing is just fine. Dexclones like the Supertech, O'Reilly and other cheap house brands (I'm running Napa 1EXT at the moment in everything I service) cover it all. These are based on Dexcool and GM uses it in all engines, including light/medium...

    Dexcool vs All Vehicles

    I've been using cheap house brand all makes all models since 2007 and not one single issue. Top off, drain and fill or full flush...doesn't matter, it works just fine in any scenario.

    Heater Core Flush

    Coolant is highly toxic, one of the most poisonous chemicals a person can encounter. Unfortunately, it really doesn't get the respect it deserves with respect to just how dangerous it is. If you're smelling it, you're breathing it.

    Confused on what coolant to use - 1993 Mustang Cobra

    Subaru Super Coolant Causes Super Confusion

    Peak Asian Blue has 2EHA in it. In fact, just like the All Vehicles coolant, they're doubling down on 2EHA - it has both potassium 2EHA and sodium 2EHA. You're in good hands, 2EHA has your back.
