This is my second season on my 27HP Kawi Liquid cooled Lazer. Since the machine was new I noticed the antifreeze level gradually drop in the reserve bottle. I attributed it to rough lawns where the liquid would slop around in the bottle and perhaps escape through the overflow hose or top. This year I noticed that the area around the radiator itself was showing antifreeze. While not a lot of moisture it was still there and my fluid level was still going down. My dealer pressure tested the radiator for me and found no leaks and no reason for it to leak but it does. Any ideas? Great machine, but I think I will go air cooled next time. One less thing to maintain.
