Hi, Ive been looking around for a coolant to use in the X and Ive come across using Water and Water Wetter more than I'd like because I have to drive to Nevada where is does get cold during winter.

I saw that Reline has its own Coolant and I like it other than the fact its pink.
So what Im asking is what coolants are you guys using?

 

I've always used a bottle of WaterWetter mixed with the cheap generic 50/50 premix green coolant.

 

I tend to flush the system every spring in my cars and last time I used the Prestone that is compatible with the green or orange coolant types. It poured out yellow and I mixxed in a bottle of Redline water wetter. As far as percentage of water to coolant, I tend to use 40% coolant and 60% water in my area to maintain good freeze protection but those in warmer climates can get away with 30/70 or 20/80 and have more cooling capacity in reserve that way. For daily driving where the thermostat is keeping the coolant flowing just enough to maintain temps around 180* F it won't make much difference but once you heat soak the cooling system at a track the combination of water wetter and an upgraded radiator can easily help keep temps down 10-20* F from peak in my experience.

 

Jensen,

Does your car see any track time? I know quite a few tracks really prefer you not use a ethelyne glycol based coolant.

If you are looking for something better than OTS stuff from Wal-Mart or a chain parts store and you want to avoid changing the fluid out a couple times a year, check out Evans coolant. I've ran that in a few of my double-duty cars, and had good results with it.

 

The 4B11T is an aluminum engine with an aluminum radaitor. You need to be using a coolant specified for such. Dexcool is a patented coolant formula developed by GM but manufactured and sold by many others.

Parts stores now stock three colors: yellow, green and orange. Huh? Isn't all antifreeze green? Isn't it all the same?

The bad news is that it doesn't come down to color matching. Isn't all antifreeze compatible? Sorry, but it isn't. There are a few cases where you can get a fast case of corrosion, some where the water pump can be both eroded and corroded to an early death, and a lot of cases where you can shorten the effective life of the antifreeze. Antifreeze itself (most commonly a chemical called ethylene glycol) doesn't wear out–ever–but the key ingredients are the rust and corrosion inhibitors, and they get used up. The most common inhibitors, silicates for aluminum protection, are used up faster than others. That's why some new cars (all General Motors, VW/Audi models) have red or orange antifreeze with a new class of inhibitors, called organic acids. Examples of U.S. brands with these organic acids: Havoline Dex-Cool and Prestone Extended Life, both recommended for five years or 150,000 miles. That's the good news.

How about just pouring orange antifreeze into every cooling system, say, yours? Sorry, but it's not that simple. The new organic acid antifreezes may be used only if the cooling system has an aluminum radiator (rather than copper-and-brass).

However, let's assume the reason you're thinking of a coolant change is because you're changing a cooling system part (pump, radiator, heater, thermostat housing) on a system with a conventional coolant, not an organic acid orange or pink. In that case, don't change to organic acid orange, even if the part you're installing is aluminum. Use a fresh fill of familiar U.S. yellow/gold or green silicated antifreeze.

The two orange extended-life antifreezes are compatible with each other, with what's factory-fill in GM cars, and with the pink in VW/Audi cars. However, they're not compatible with a special orange antifreeze in Chryslers, a special "hybrid" mix of organic acids and silicates. The green in most Japanese cars contains no silicates, so it's not the same as the green in the parts store. The yellow in some European cars contains some silicates, but it's very different from yellow Prestone, the top-selling U.S. brand. And then there is red antifreeze used by Toyota, and blue used on some European and Korean cars.

What about just topping up a system that's low? What kind should you use? If the system (except for Chrysler) has orange or pink, use Prestone or Havoline orange for top-up. All you have on hand is regular U.S. yellow/gold or green? Well, if you're desperate, use what you've got, because it's better than running low on coolant and possibly overheating. But the mixture is shortening the life of the antifreeze. By how much? It would take lab tests to tell, so the best deal is to do the equivalent of a "retrofit." Can you retrofit all systems? Sorry, the answer is no. What about draining green or yellow/gold from the radiator and refilling with orange? Is that considered a "retrofit"? No, and you'd better not try that, either.

What if the system has Japanese green, Toyota red, Korean or European blue, or European yellow? As we noted, European and Korean formulas have silicates, so U.S. green or yellow/gold is all right, but it slightly compromises the extended life formulas some have. Typically all that means is: Change at 30,000 instead of 36,000 miles. The Japanese green and red antifreezes have no silicates, but they are very different from U.S. orange. If you really drain out the old antifreeze from any of these systems (thoroughly rinse the system with fresh water), you certainly can refill with a U.S. yellow/gold or green silicated antifreeze.

Refill the system to half its capacity with coolant. Then add distilled water to fill, achieving a 50 percent concentration of coolant. Check the concentration with a hydrometer.


Still confused? I am! HAHA To make matters worse a recent study showed that Water Wetter (which I have been a loyal user of for 15+ years) makes no improvement to the cooling sysem under lab testing.

As for me...I will use the factory coolant and skip the Water Wetter.

 

I run distilled water with a bottle of Motul MoCool to help keep the water pump happy. A lot of other guys who hit the track frequently do the same, and I've heard of no issues. If you don't see cool weather, there's no more efficient coolant than water with a mild additive.

 

So confusing... My coolant level is below the low mark "15k mils no leaks is this normal??" what should i use to top it off?? Need help

 

That's fairly normal for an Evo actually, you can either go to the dealer and buy a jug of Mitsu coolant, or any auto parts store and get a jug of 50/50 premix long-life coolant.

 

Sorry for bumping this old thread, but I'm at a loss. Checked my fluids today (22k miles) noticed the coolant was low, no problem opened it and its BLUE?!!! huh, is this the dex-cool or is this regular gylcol. Anyway to tell?... Or am i just gonna have to flush and start over, if so which of the two is preferred?

NEVERMIND - figured it out... But for anyone else who runs across this, I found the answer by calling the stealership, evidently 2010+ has special coolant they put in the evo, and the parts department person said he didn't think it was possible to mix it with anything else... SO i decided to purchase said coolant, gets worse, it's 30$ for the already mixed 50/50 blue batch... such a rip off....

 

SavageGSR,

do you have the part number for that special coolant or name? Was it in mitsu-labeled packs?

 

I don't have the part number, just drove down to the stealership; I can get it for you over the weekend if need be. It was in Mitsubishi labeled container, black jug, with white label, very plain. AND OF COURSE BLUE coolant color!!!

 

Our coolant is special like others from Japan manufacturers, it uses P-OAT technology. I think its made by CCI company like Mazda's and Honda's ones.

In latest 2012 manuals Mitsubushi specifies new version, cited:

"Recommended antifreeze: DIA QUEEN SUPER LONG LIFE COOLANT PREMIUM or equivalent*
NOTE:
*similar high quality ethylene glycol based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technology"

From different sources I heard it has different color now in car right from the Japan factory.

PS:

P-OAT coolants:

Ford WSSM97B55 (Motorcraft Specialty Green Engine Coolant);
Nissan Anti-freeze Coolant (L250)
