Coolant Leak here!

I just did a stator replacement, got the bike back together, and now have a coolant leak on the left side, top rear, coming from that black pipe/hose at the top.

Whats the best fix?

See your other thread. :P

Unbolt and slide out the tube, gently. Replace the o-ring.

Thanks guys.


Now my temp gauges seems to be not working. Its stuck all the way to the left at C, even after about 20 mins of riding today on a hot sunny day. It normally stays about mid way.

Is the little wire on the bottom of the engine connected? Super thin wire.

Is it a green wire?

The fan is working, just not the needle/gauge.

Ok figured it out.
When I removed the tank to get at that hose to replace the o-ring, the wire up top on the radiator hose housing must have came off.
Plugged it back in, it works lol.

The last few weeks have been one issue after another.
Dead battery, fried stator and r/r, tear apart and remove the engine, replace stator and r/r, put back together, do coolant and lubes, then end up with a coolant leak, and then a busted travel trailer I had to hurry up and get fixed, then this thermostat gauge issue.

Now I should be ready to hit the road on my vacation ride to Algona Iowa for the big biker freedom rally!!

I've got a little leak there too. Is that O-ring special in any way? Could I just go with a same size replacement from Ace or something?

And where is the wire you are talking about? I thought the temp gauge sensor what near the radiator cap. Or are there multiple sensors? Mine also reads very low ever since I replaced the engine.

My local kawi dealer had then in stock, 60cents each.

The wire I had disconnected was up by the radiator cap. But I think there's another on underneath at the back of the engine.

OK, I'll look, but was pretty sure I had reconnected everything.
