Overflow bottle for Rotax
I am curious the length of time your plastic overflow bottles have lasted. My first one was damaged when the zip tie holding it on broke. I replaced it with a new Rotax plastic bottle which was about 58 dollars a year and a half ago. Now they are $78.00 which i feel is Robbery. Come on Rotax stop ripping us off. What hose are you all using that connects from the plastic bottle to the metal tank? The sun and high temps in arizona play havoc on this type of plastic. Next time I am thinking of making an overflow thank out of an aluminum bottle that would last for a lifetime and i could get for 20 bucks. So, have your tanks lasted and what hose do you have on there to connect the two?

Roger, mine has lasted since 2013 with no issues so far. My radiator cap not so much.

Hey jim what was your symptoms of a bad radiator cap? Lately I have been getting excess radiator fluid on top of my bottle and now you got me thinking i might have a bad radiator cap. 🙂

I started finding a small amount of antifreeze on the cowling under the motor. It happened twice before I figured it out. The seal on the cap had come loose from the metal surface and was not providing a seal. I carefully pushed the seal back in place and have had nothing since. Was weird. Nothing like that in my previous experience to make me look for the leak like that in any vehicle I have ever worked on. I have had radiator caps fail on other types of vehicles and always found the problem with a pressure test of the cap. This was obvious as soon as I pulled the cap and looked at it. The only thing I can think of is it happened when I check the fluid level before each flight.

You definitely have me looking closer at my cap and any seals. Great comments thanks Jim.
