Waterless Coolant
I was wondering if anyone here has used waterless coolant, such as [URL=""]Evan's Coolant[/URL]. I saw a video on Jay Leno's garage where Jay was really pushing the stuff, [URL=""]HERE[/URL] . Just looking for more input.

Interesting read. This is one of the responses that was on that website:

I'm kinda excited about that alternative. Ive tested cars with a multimeter, (ground to body, positive in the "coolant", any reading indicates too much water) and most have had there "coolant" turned into battery acid. Try it, see what you get out of your radiator. It's scary. It's eating your engine from the inside out!

I never really thought of that... but then again, I've always flushed my systems every yr and a half. Wonder how long others are waiting?

Nice link. Thanks

BTW... Anyone look at the pricing ? WTF

I bought my WRX brand new in early 2007.

2/24/09 @ 30,100 mi. = Drained coolant. Filled with distilled water only, turned car on and idled engine to operating temp, drained (process repeated twice since the water looked almost clear when it drained the second time). Filled with 50% OEM coolant, 50% distilled water, OEM coolant conditioner, and Redline Water Wetter.

8/26/10 @ 60,100 mi. = Same as above.

12/19/11 @ 86,300 mi. = While being protuned, the tuner noticed that my engine temp was not dropping as quickly as it should. The tech noticed that my overflow container was full of dirty gunk, so he cleaned that out really well and replaced one of my radiator caps since he suspected it was partially blocked by the same gunk. After that, the temperature dropped much quicker, so I immediately had my coolant system professionally flushed in an attempt to get as much gunk out of the other internal parts as possible. I suspect the gunk buildup was due to me simply draining and refilling my coolant and never actually having the coolant system professionally flushed.

It's probably too late for me to fully benefit from this product now, but it's probably something I'll consider if I buy another brand new car or build an engine.

Considering my most recent cost of replacing my own coolant:
(1x) 1 Gallon Subaru OEM Undiluted Coolant = $19.00
(1x) 1 Bottle Subaru OEM Cooling System Conditioner = $2.00
(1x) 1 Bottle Redline Water Wetter = $10.49
(5x) 1 Gallon Distilled Water = $0.83/ea. = $4.15
Total = $35.64

Since I've changed my coolant three times now, the one time cost of $43.95/gallon for the Evans coolant doesn't seem too terribly outrageous.

That's where you get bent

Well, I didn't include gas/wear/tear/time to drive to the Subaru dealership and Walmart to get my supplies three separate times either ;)

John, you have a whole room dedicated to receipts, dont you?

I think its worth a whirl, I may have to place that order myself.

...maybe. I just like keeping records. Call it OCD?

I was looking at waterless coolant for my new car (that I pick up... today... can't sleep). Anyhow, since I can't sleep, I decided to do some research and it looks like Subaru uses waterless coolant in the newer cars. I found [URL=""]the official 2011 maintenance schedule[/URL], and it says that coolant is good for 11 years. How cool is that :)

BTW, I have you beat man show, I have receipts for purchases and repairs of cars I no longer own. Just can't let them go...
