Off and on radiator leak and overheating - any suggestions?

[David Mitchell]

I have a couple of strange issues going on with my 2014 Can-Am Spyder RT. First, a few weeks ago, it started to overheat. I had just parked after driving for about 20 minutes and steam came off of the engine. I looked underneath and saw fluid gushing out, but couldn't determine from where. So I let it cool down and then took it back home where I put it up on a rack and ran the bike to get it to overheat again. It didn't. I tried driving it around over and over again but it still did not leak. However, the temperature gauge spiked all the way up to the ninth bar and I turned it off. After further investigation, it seems that the fans, which were working when it first overheated when I was driving it, are not working anymore. I checked the relay and it seems to ohm out correctly (is there something else I'm supposed to test on the relay?) As long as I ride it and don't stop for long, it'll stay at four bars on the temperature gauge and it does not leak any more. Now the only thing I have done is I flushed it and replaced the fluid.


As for the fan I'm guessing somehow the temperature gauge went bad about the same time it started to leak. However, not sure what to do to find the leak that doesn't exist anymore.

Suggestions? Thank you in advance for your help

Check to make sure your radiator cap is on tight and right on the bottle. it's hard to make sure it goes on straight, and it also has like a two-step hook on it, make sure it is all the way on! Ask me how I found that out!

I though about that. It's tight. Any other suggestions? I'm more concerned about the fans.

I had a 2013 RT and it would puke coolant similar to what you describe. It turned out to be a radiator cap.
