Someone told me about replacing the standard coolant with Evans racing coolant. Euroflier Rookie 10 SoCal 1 My 550 tends to get a little warm under the hood cruising around town on hot days. Europactor EuroPart European Engine Alliance Evans Evasko Evco Plastics. So much so that we're thinking of putting on the oil line an optional thermostat Tecnam approves. Evans Coolant Discussion in ' 456/550/575 ' started by Euroflier. Coolant CoolPro Cooper Cooper Bessemer Coopers Copar Copeland Corp. So much so that even in the summer we have to put some aluminum tape over part of either the oil radiator, coolant radiator, or both to get them to run up in optimum tempurature ranges for oil for decent part of the flight. I MIGHT be able to find out by calling the A&P guy who did that 3 years ago.Īs for the reported issue of the engines running hot because Evans doesn't have as high heat transfer capacity:Īll I can say is that in OUR case both Rotax engines I have (the old 80HP on a Skyranger, newer 100 on Tecnam), both under pretty tight cowls, (one with traditional coolant, one with Evans) both run very much on the COOL side, even when climbing with outdoor temps high. Good point about finding out if they're mixable from Evans(will go to Evans and try to find that out) because in the engine log the note on installing Evans doesn't say WHICH one is in there. Thanks for your, as usual, considered advice, Roger. Open air engines usually didn't have an issue, but tight cowl engines did. This put many up to and or over the max temp for the engine. Most have gotten away from Evans because it carries a 20F-30F temp penalty depending on the application. Unless the coolant in the system has a color you may not be able to tell which one is in there. This may be a better question about mixing either of the three directly with Evans unless it states something on their website.

(I know adding more than a tiny trace of water to Evans is a general no-no,Īnd AFAIK shouldn't add other coolants to it.) I know that Rotax isn't pushing Evans as hard as it once was, and that the other coolants are fine, but since it's in there already figure I'd keep it.īut want to have a little extra around in case I ever need to top it up. Unlike our older 912UL this one had Evans coolant put in it a couple of years ago.
