Now that my radiator is about to blow the subject comes up again has anyone tried Evans coolant??????? I have a friend with a 57 Chevy who has used it for 10 years and loves it, It is one of those seems like it is too good to be true products, no water, no pressure, no corrosion, non toxic, no sh*t??? http://www.evanscooling.com/main27.htm Rob I dont want to be the first to try it!! :-0
Rob, Evans looks interesting, amazing actually, but like you I wouldn't want to be the crash test dummy. I can tell you though, that I put in Cosworth Coolant (additive to my existing glycol/distilled water system) with dumbfounding results. Took a spirited high RPM low speed malibu/stunt canyon run today (hot day) and water temps stayed @ 90 c (euro guages) or below, massive improvment on my 308 QV. www.liquidcosworth.com I'll watch this thread though for Evans testimonials -Luigi
Have the stuff herw and debated puting it in... until i had a small coolant line leack (easy fix) at Lime Rock Park. If you go with Evans, you can not top off with water. Well, you can in case of emergency... If you want some, i have 6 gallons of it here for sale... cheap.
I gave Evans Coolant a two year long test in my '84 Chevy Silverado with a 4-row heavy duty radiator and had zero problems till this summer. I was on a desolate stretch of highway in southern Colorado and the air temp was 104F. The engine temp said 210F and I was having an engine problem I thought was vapor lock that turned out to be fuel pump failure. I dumped the Evans and put in regular antifreeze and water and my engine temp dropped to 180F. Not actually a problem with Evans coolant but it did, in high heat conditions, cause my engine to run very hot. Caused by '64 Buick to run hot (idiot light stayed on) even though the ambient time was 80F. It had a two-row radiator. I called Evans from the road and they said I would have to get a bigger radiator if I wanted to use their coolant in the Buick. I think it is a good product, just works well in some vehicles and not so well in others.
It goes in with the standard 50/50 mix buts acts as corrosion inhibitor and also reduces surface tension/ aids heat transfer....similar to water wetter, my understanding.. I use the whole RP lube line (20-50W, 75-90W gear), so grabbed this stuff as well....
I'm putting distilled water and puple ice in my Boxer (after thoroughly cleaning out the system). Did the same with my Ducati and the results were a noticable reduction in running temps. Good stuff.
*thumbs up* but...it didn't fix the pin hole leak in my radiator!!! ROTFLMAO! Or the shorted cooling fan........
I have Evans coolant in my supercharged 77 308GTB with an electric coolant pump and an aluminum radiator. At the moment I'm having trouble getting the coolant warm enough but it's due to pump/thermostat issues not the coolant. I have it in the intercooler system also. We've installed it in several vintage Lamborghinis and a vintage Ferrari racing car with no problems at all. If you want all the details go to evanscooling.com but in short it has no water in it so it does not corrode, it boils at 380F. You can run it at lower pressure (7lb cap, or lower) to ease stress on the coolant pump seal and hoses. It also does not produce steam pockets around the combustion chambers which can induce knock and all the related problems. It's clycol based so in a pinch you can add water but then, to retain it's advantages, you would need to flush it out and replace it with pure coolant once yopu got the car home. The biggest disadvantage is that it costs about $32.00/ gallon. Most cars require up to 4 gallons so that is $128.00. I think it's a good investment well worth the price.
